Opinion for the Court filed by
Circuit Judge WILLIAMS.
Concurring Opinion filed by Senior Judge MacKINNON.
WILLIAMS, Circuit Judge:
Appellant William Mondy brought suit in forma pauperis alleging that his dismissal from his post at Walter Reed Army Medical Center was racially discriminatory in violation of Title VII of the Civil Rights Act of 1964, 42 U.S.C. § 2000e et seq. (1982) (the “Act”). As the parties present the case, there were two procedural defects in the bringing of the suit: (1) Mondy’s complaint named the wrong defendant — his activity commander, Colonel Thomas Sweeney, rather than the Secretary of the Army; (2) the United States marshals, who pursuant to 28 U.S.C. § 1915 (1982) issue and serve process for in forma pauperis plaintiffs, delayed service for nearly four months, long past § 2000e-16(c)’s 30-day deadline. (The time runs from the date of plaintiff’s receipt of notice of final action on his claim. Here the letter was delivered to Mondy’s address on September 23, 1985, which is deemed the date of receipt; this made October 24, 1985 the deadline. Mondy filed his papers with the court about 9:30 A.M. on October 18, 1985, and the marshals did not serve the United States Attorney until February 14, 1986.)
Because of the provisions of the Federal Rules of Civil Procedure on amendment of complaints and on service of the government and its agents and officers, an error in naming the proper defendant would not be enough, standing alone, to defeat Mondy’s claim. Rule 15(c) allows a pleading amendment, correcting the identity of the party charged, to “relate back” to the date of the initial pleading if the correct party received adequate notice as defined by the rule. (Schiavone v. Fortune, 477 U.S. 21, 106 S.Ct. 2379, 91 L.Ed.2d 18 (1986), makes clear that this notice must have been received within the original time limit.) The rule specifies that when suit is brought against an agent or officer of the United States, service on the United States Attorney, his or her designee, or the Attorney General, satisfies these notice requirements. Rule 4(d)(5), in turn, explains that one serves an agent or officer of the United States by “serving the United States”; Rule 4(d)(4) makes clear that one does so by serving the United States Attorney (or his or her designee) and the Attorney General.
While Mondy may have mistakenly believed that Colonel Sweeney was the proper Title VII defendant, he used his military title in the complaint and thus clearly recognized him as an officer or agent of the United States. Had he been effecting service himself, that recognition would have led him to Rule 4(d)(5) and thence to Rule 4(d)(4). Service thereunder would have more than satisfied Rule 15(c)’s prerequisites for relation back. His mistaken choice of defendant would thus have been curable.
Mondy was, however, proceeding in for-ma pauperis. As such, he lawfully relied upon the marshal’s office to effect service. His original complaint made clear his intent to sue a federal officer. It named Colonel Sweeney as defendant and specified his address as “United States Army, Institute of Dental Research, Walter Reed Army Medical Cénter.” The marshal’s office so understood the complaint; it delivered a copy to the U.S. Attorney on February 14. If it had completed this service by the October 24 deadline, Mondy would have been able to amend his complaint pursuant to Rule 15(c). Had it not been coupled with the marshal’s delay, Mondy’s error would have been readily and fully correctable.
On May 14, 1987, plaintiff, by then represented by counsel, took the appropriate step to mend the original error — he filed an amended complaint naming the Secretary of the Army as defendant. (The marshal delivered a copy to the United States Attorney’s office the next day.) The Army moved to dismiss for want of subject matter jurisdiction, on the ground that plaintiff’s failure to meet the 30-day limit of 42 U.S.C. § 2000e-16(c) defeated the court's jurisdiction.
The district court found that as the amended complaint had not been served on any proper party defendant within 42 U.S.C. § 2000e-16(c)’s 30-day period, the plaintiff had failed to meet the requirements of Rule 15(c), as clarified in Schiavone v. Fortune. And because the court believed that the time limit was jurisdictional (i.e., not subject to equitable tolling for any reason) under this court’s opinion in Hofer v. Campbell, 581 F.2d 975 (D.C.Cir.1978), cert. denied, 440 U.S. 909, 99 S.Ct. 1218, 59 L.Ed.2d 457 (1979), it granted the motion to dismiss. Because we believe that § 2000e-16(c) is subject to equitable tolling, and that this case calls for application of the doctrine, we reverse and remand.
I. Availability of Equitable Estoppel
The Supreme Court has not yet considered whether § 2000e-16(c)’s 30-day limit is a jurisdictional requirement or is, instead, a statute of limitations subject to equitable estoppel. The question is one of first impression in this court. However, in Zipes v. Trans World Airlines, Inc., 455 U.S. 385, 102 S.Ct. 1127, 71 L.Ed.2d 234 (1982), the Supreme Court held that the analogous 90-day (now 180-day) time limit for filing a Title VII claim against a private employer with the Equal Employment Opportunity Commission (“EEOC”) was not jurisdictional and was, “like a statute of limitations, ... subject to waiver, estoppel, and equitable tolling.” Id. at 393,102 S.Ct. at 1132. The Court based its decision upon (1) Congress’s having expressed the time limit in a provision (42 U.S.C. § 2000e-5(e)) entirely separate from the one that defines the jurisdiction of the courts (§ 2000e-5(f)), 455 U.S. at 394-95, 102 S.Ct. at 1133; (2) legislative history, id. at 394-95, 102 S.Ct. at 1133; (3) prior cases reflecting an assumption that the filing requirement was not jurisdictional, id. at 397-98, 102 S.Ct. at 1134-35; and (4) Title VII’s remedial purpose, id. at 398, 102 S.Ct. at 1135.
The circuit courts have extended Zipes to § 2000e-5(f)(l)’s 90-day limit for filing Title VII claims in district court against private employers. See e.g., Gonzalez-Aller Balseyro v. GTE Lenkurt, Inc., 702 F.2d 857, 859 (10th Cir.1983); Rice v. New England College, 676 F.2d 9, 10 (1st Cir.1982); Gordon v. National Youth Work Alliance, 675 F.2d 356, (D.C. Cir.1982). Indeed, the Supreme Court in Zipes had rested its treatment of § 2000e-5(e) in part on its having previously treated § 2000e-5(f)(l)’s time limit as non-jurisdictional in Mohasco Corp. v. Silver, 447 U.S. 807, 811 n. 9, 100 S.Ct. 2486, 2490 n. 9, 65 L.Ed.2d 532 (1980). Zipes, 455 U.S. at 398, 102 S.Ct. at 1135.
Although closely analogous, the question before us today differs from those resolved in Zipes and Gordon. The time limit in question governs the filing of Title VII claims against the government. Extension of equitable tolling to such claims is not automatic by any means, for the government enjoys sovereign immunity, and waivers of such immunity are narrowly read. United States v. Mottaz, 476 U.S. 834, 106 S.Ct. 2224, 2229, 90 L.Ed.2d 841 (1986); Soriano v. United States, 352 U.S. 270, 276, 77 S.Ct. 269, 273, 1 L.Ed.2d 306 (1957).
In a slightly different context, however, we extended Zipes to claims against the government. In Saltz v. Lehman, 672 F.2d 207 (D.C. Cir.1982), we found that the EEOC’s 30-day time limit (29 C.F.R. § 1613.214(a)(1) (1987)) for bringing Title VII complaints to the attention of the agency Equal Employment Opportunity Counselor (“EEO Counselor”) was subject to equitable tolling. After recognizing and resolving the concern that the time limit was jurisdictional, the court rejected equitable tolling on the specific facts of the case. Since dismissal without any reference to those facts would have been appropriate if the untimeliness were jurisdietional, and a court is responsible to determine its own jurisdiction regardless of the parties’ views, Saltz represents a holding on the jurisdictional point even though the defendant conceded that the rule was subject to equitable tolling. Id. at 208-09. See also Jarrell v. United States Postal Service, 753 F.2d 1088, 1091 (D.C. Cir.1985) (reading Saltz to hold that the EEOC’s 30-day rule was subject to equitable tolling, and remanding for application of the doctrine); cf. Kizas v. Webster, 707 F.2d 524, 545 (D.C. Cir.1983) (similar reading of Saltz in dictum).
Although the language in Saltz is broad enough to encompass all time limits for all Title VII suits where the government is the employer, e.g., Saltz, 672 F.2d at 209 (“Title VII’s time requirements are subject to equitable modification”), the case does not explicitly address the time limit here in question — the one established by 42 U.S.C. § 2000e-16(c). The present case might be distinguished from Saltz on the basis of differences in either (1) the language and structure of the controlling provisions (42 U.S.C. § 2000e-16(c) and 29 C.F.R. § 1613.214(a)(1)), or (2) the status of the provisions (here a statute, in Saltz a mere agency regulation). We conclude that neither distinction is compelling.
Courts have taken exceptionally emphatic language as a sign of legislative intent that a time limit should be jurisdictional. For example, in King v. Dole, 782 F.2d 274, 276 (D.C. Cir.1986), this court relied on the “clear and emphatic” character of 5 U.S.C. § 7703(b)(2) — “[n]otwithstanding any other provision of law, any such case filed ... must be filed within 30 days____” Compared with the phraseology considered in Saltz (“[t]he agency may accept the complaint for processing in accordance with this subpart only if [the aggrieved employee] brought [it] to the attention [of the EEO Counselor] within 30 calendar days ... ”) or Zipes (“[a] charge under this provision shall be filed within [one hundred and eighty] days after the alleged unlawful employment practice occurred”), the words of 42 U.S.C. § 2000e-16(c) certainly have no special ring: “Within thirty days of receipt of notice of final action ... an employee or applicant for employment, if aggrieved by the final disposition of his complaint ... may file a civil action as provided in section 2000e-5 of this title____”
Moreover, 42 U.S.C. § 2000e-16(d) states that the provisions of §§ 2000e-5(f)-(k) (which define the jurisdiction of the district court, provide for appeals, attorneys’ fees, etc., in actions against private employers) govern Title VII actions against federal government employers. This structural point is relevant for two reasons. First, the Court in Zipes found significance in the time limit’s being placed in a provision separate from the sections governing jurisdiction, see p. 1054 supra, and the structure is similar here. Second, the cross-reference from § 2000e-16(d) to § 2000e-5(f)-(k) suggests a parallelism between § 2000e-16(c) and § 2000e-5(e); the latter is what the Court held non-jurisdictional in Zipes. Thus, the statutory language and structure do not suggest that § 2000e-16(c) is any more jurisdictional than § 2000e-5(e) or 29 C.F.R. § 1613.214(a)(1).
Nor does the difference between statute and regulation seem controlling. Most of the courts that have discussed whether the time limits in Title VII actions against the government are jurisdictional have not distinguished between 42 U.S.C. § 2000e-16(c) and 5 C.F.R. § 1613.214(a)(4). Cooper v. Bell, 628 F.2d 1208 (9th Cir.1980), is the only case in which a court has differentiated between the two for the purpose of deciding an equitable tolling issue. Although binding Ninth Circuit precedent held § 2000e-16(c)’s time limit to be jurisdictional, Mahroom v. Hook, 563 F.2d 1369, 1374 (9th Cir.1977), cert. denied, 436 U.S. 904, 98 S.Ct. 2234, 56 L.Ed.2d 402 (1978), the panel in Cooper v. Bell found 5 C.F.R. § 1613.214(a)(4) to be subject to equitable extension. The court noted that although § 2000e-16(c) required exhaustion of administrative remedies, and 42 U.S.C. § 2000e-16(b) authorized the Civil Service Commission to promulgate regulations to effectuate the statute’s policies, “Congress did not premise district court jurisdiction” on timely filing of an administrative complaint. The time limit was solely the creature of the Civil Service Commission— “merely an administrative procedural requirement.” 628 F.2d at 1213.
The only other court to expressly consider whether the regulatory status of 29 C.F.R. § 1613.214(a)(1) might justify special treatment has rejected that notion. In Sims v. Heckler, 725 F.2d 1143 (7th Cir. 1984), the court, viewing § 2000e-16(c)’s time limit as jurisdictional in light of the federal government’s sovereign immunity, extended that view to the EEOC’s regulatory time limit. It reasoned that “[v]alid administrative rules legislative in nature have ‘the force and effect of law,’ ” id. at 1146 (quoting Chrysler Corp. v. Brown, 441 U.S. 281, 295, 99 S.Ct. 1705, 1714, 60 L.Ed.2d 208 (1979)), and concluded that 5 C.F.R. § 1613.214(a)(4) was “ ‘as binding on the courts as any statute enacted by Congress,’ ” 725 F.2d at 1146 (quoting Production Tool v. Employment & Training Administration, 688 F.2d 1161 (7th Cir.1982)). Although we disagree with Sim's apparent view that § 2000e-16(c) is jurisdictional, we agree that 29 C.F.R. § 1613.214(a)(l)’s regulatory status is not a critical support for its being subject to equitable tolling. It is clear that in holding 29 C.F.R. § 1613.214(a)(4) subject to equitable estoppel in Saltz v. Lehman, this court did not distinguish it from other statutory Title VII time restrictions. It in no way relied upon the fact that the time limit was promulgated by an agency rather than by Congress. We are not persuaded that we should introduce such a distinction at this point.
In finding the Title VII filing limit non-jurisdictional, we do not suggest, of course, that it may be disregarded with impunity. The court’s equitable power to toll the statute of limitations will be exercised only in extraordinary and carefully circumscribed instances. The Supreme Court has suggested in Baldwin County Welcome Center v. Brown, 466 U.S. 147, 104 S.Ct. 1723, 80 L.Ed.2d 196 (1984) (per curiam), that courts may properly allow tolling where “a claimant has received inadequate notice, ... where a motion for appointment of counsel is pending and equity would justify tolling the statutory period until the motion is acted upon, ... where the court has led the plaintiff to believe that she had done everything required of her, ... [or] where affirmative misconduct on the part of a defendant lulled the plaintiff into inaction.” Id. at 151, 104 S.Ct. at 1725-26 (citations omitted). We think the present case justifies application of equity without in any way bending those principles.
II. Application of Equity
As noted above, a mistake in naming Colonel Sweeney as defendant would not have subjected Mondy’s claim to the bar of § 2000e-16(c) if he had straightforwardly pursued his error through the procedures of service. (Cf. “The road of excess leads to the palace of wisdom.” W. Blake.) Instead he allowed service to be made by the district court, as 28 U.S.C. § 1915 entitled him to do. The caption of the complaint made it clear that he was suing a federal officer. If the marshal’s office had simply followed the path laid out by Rule 4(d) within six days of Mondy’s filing, Mondy would have been entitled to relation back under Rule 15(c). While the equities may not weigh in favor of a plaintiff who counts on “same day service,” Conforte v. Commissioner of Internal Revenue, 459 U.S. 1309, 1311, 103 S.Ct. 663, 664, 74 L.Ed.2d 588 (1983), Mondy’s behavior did not set up any such photo-finish. The Army does not assert that it has been disadvantaged by its belated notice of appellant’s claim. In these circumstances, fairness demands that the statutory time limit be tolled.
We note that the Seventh Circuit, which treats the 30-day deadline as a jurisdictional prerequisite, recently held that the time limit was tolled during the pendency of a petition to proceed in forma pauperis. Paulk v. United States, 830 F.2d 79, 83 (7th Cir.1987).
******
Mondy should thus be deemed to have made timely service on the United States and to have satisfied the requirements of Rule 15(c). The decision of the lower court is reversed and the case remanded for further consideration.
. Under 42 U.S.C. § 2000e-16(c), the only proper defendant is "the head of the department, agency, or unit, as appropriate.” As noted by the Seventh Circuit, "[t]his cryptic phrase provides little guidance to litigants.” Paulk v. Department of the Air Force, 830 F.2d 79, 80 (7th Cir.1987). Because the statutory language is so unenlightening, we strongly endorse the suggestion made by the Third Circuit in Williams v. Army & Air Force Exchange Service, 830 F.2d 27, 31 (3d Cir.1987), that federal agencies amend their right-to-sue letters to indicate who should be named defendant. In this case, Mondy does not dispute appellee’s contention that he ought to have named the Secretary of the Army. Thus for purposes of this opinion we will proceed on the assumption that Mondy erred in naming Colonel Sweeney. However, as the question is not now before us, we do not reach or purport to decide the question of who may be a proper Title VII defendant under § 2000e-16(c).
. The district court practice is to defer service of in forma pauperis complaints until the plaintiffs motion to proceed in forma pauperis is granted. Here the extreme delay arose out of the fact that when the screening district judge granted the in forma pauperis motion, he simultaneously dismissed the case sua sponte. Plaintiff moved to alter that judgment, and on February 10, 1986 the district court agreed and reinstated the case; service by the marshals followed promptly.
. Rule 15(c) provides as follows:
(c) Relation Back of Amendments. Whenever the claim or defense asserted in the amended pleading arose out of the conduct, transaction, or occurrence set forth or attempted to be set forth in the original pleading, the amendment relates back to the date of the original pleading. An amendment changing the party against whom a claim is asserted relates back if the foregoing provision is satisfied and, within the period provided by law for commencing the action against the party to be brought in by amendment that party (1) has received such notice of the institution of the action that the party will not be prejudiced in maintaining his defense on the merits, and (2) knew or should have known that, but for a mistake concerning the identity of the proper party, the action would have been brought against the party.
The delivery or mailing of process to the United States Attorney, or the United States Attorney’s designee, or the Attorney General of the United States, or an agency or officer who would have been a proper defendant if named, satisfies the requirement of clauses (1) and (2) hereof with respect to the United States or any agency or officer thereof to be brought into the action as a defendant.
.Rule 4(d)(4) & (5) provide as follows;
(d) Summons and Complaint: Person to be Served. The summons and complaint shall be served together. The plaintiff shall furnish the person making service with such copies as are necessary. Service shall be made as follows:
(4) Upon the United States, by delivering a copy of the summons and of the complaint to the United States attorney for the district in which the action is brought or to an assistant United States attorney or clerical employee designated by the United States attorney in a writing filed with the clerk of the court and by sending a copy of the summons and of the complaint by registered or certified mail to the Attorney General of the United States at Washington, District of Columbia, and in any action attacking the validity of an order of an officer or agency of the United States not made a party, by also sending a copy of the summons and of the complaint by registered or certified mail to such officer or agency.
(5) Upon an officer or agency of the United States, by serving the United States and by sending a copy of the summons and of the complaint by registered or certified mail to such officer or agency. If the agency is a corporation the copy shall be delivered as provided in paragraph (3) of this subdivision of this rule.
. Since 1978, various panels have fought a footnote war over whether this court held the § 2000e-16(c) 30-day limit to be jurisdictional in Hofer v. Campbell, 581 F.2d 975 (D.C.Cir. 1978), cert. denied, 440 U.S. 909, 99 S.Ct. 1218, 59 L.Ed.2d 457 (1979). See, e.g., King v. Dole, 782 F.2d 274, 277 n. 3, (D.C.Cir.), cert. denied, 479 U.S. 856, 107 S.Ct. 194, 93 L.Ed.2d 126 (1986) (Hofer held the 30-day limit for filing claims in district court jurisdictional); Bethel v. Jefferson, 589 F.2d 631, 641 n. 64 (D.C.Cir.1978) (describing Hofer’s "jurisdictional” language as dictum); Loe v. Heckler, 768 F.2d 409, 419 n. 20 (D.C.Cir.1985) (commenting that the 30-day time limit issue is an open question). In Hofer there was no issue of waiver, estoppel or equitable tolling, and there was therefore no need for the court to decide whether the 30-day time limit was jurisdictional and its observation on the subject was dictum. Because the dictum was itself based upon earlier dictum in Richardson v. Wiley, 569 F.2d 140 (D.C.Cir.1977), and the court provided no independent reasoning on the topic, the case has no effect on the matter at hand.
The majority of the other circuits that have ruled on the issue have found the time limit to be non-jurisdictional. See, e.g., Milam v. United States Postal Service, 674 F.2d 860, 862 (11th Cir. 1982); Martinez v. Orr, 738 F.2d 1107, 1110 (10th Cir.1984); Hornsby v. United States Postal Service, 787 F.2d 87, 89 (3d Cir. 1986). But see Sims v. Heckler, 725 F.2d 1143 (7th Cir.1984).
. 42 U.S.C. § 2000e-16 contemplates the invocation of administrative remedies as a condition precedent to suits in the federal courts. Brown v. General Services Administration, 425 U.S. 820, 832, 96 S.Ct. 1961, 1967, 48 L.Ed.2d 402 (1976). The statute itself is silent as to the time period within which an aggrieved employee is to file her initial administrative charge. However, the Civil Service Commission promulgated 29 C.F. R. § 1613.214(a)(1) (1987), formerly 5 C.F.R. § 713.214(a)(1) (1978), which requires employees to bring charges to the attention of an EEO Counselor within 30 days of alleged discriminatory conduct. Federal government equal employment opportunity enforcement was later transferred to the EEOC by the President, pursuant to 5 U.S.C. §§ 901 etseq. (1982), in Section 3 of Reorganization Plan No. 1 of 1978, 43 Fed. Reg. 19,807, 92 Stat. 3781, reprinted as an attachment to 42 U.S.C. § 2000e-4 (1982).
. See, e.g., Stuckett v. United States Postal Service, 469 U.S. 898, 105 S.Ct. 274, 83 L.Ed.2d 210 (1984) (White, J., and Rehnquist, J., dissenting from denial of petition for writ of certiorari); Martinez v. Orr, 738 F.2d 1107, 1110 (10th Cir. 1984); see also Hewlett v. Russo, 649 F.Supp. 457, 459 (E.D.Va.1986) (recognizing that past cases have decided both the administrative and district court time limit questions, but according no significance to the difference in contexts).
. The Cooper v. Bell, court also offered two justifications, apart from its mere regulatory character, for treating 29 C.F.R. § 1613.412(a)(1) as subject to equitable tolling. First, it pointed to the existence of express provisions for tolling in specific circumstances. 628 F.2d at 1213. While courts undoubtedly often infer a general policy from specific provisions, they as often apply the maxim expressio unius est exclusio alterius. (The two approaches suggest a paraphrase of Newton’s third law of motion; "For every maxim there is an equal and opposite maxim.” Cf. Llewellyn, Remarks on the Theory of Appellate Decision and the Rules or Canons About How Statutes Are to Be Construed, 3 Vand.L.Rev. 395, 401-06 (1950); see especially id. at 405 & nn. 41-42.) Standing alone, the point seems only a weak distinction between the statute and the regulation.
The court also argued that the need for equitable tolling was strongest at the earliest stage of proceedings, when the claimant will be less schooled in the administrative byways and less articulate about the claim. Id. at 1213 & n. 10. We think the distinction significant, but militating more in favor of adjusting the burden for establishment of equitable tolling than of barring it altogether at the stage of court filing.
