Appellants were convicted of manslaughter and the judgments and commitments were filed on May 7, 1958. The District Court, on May 28, 1958, .granted them leave to appeal in forma pauperis and notices of appeal were filed by their counsel that same day.
The cause is now before us on the Government’s motion to dismiss the appeals for lack of jurisdiction. The Government argues that these notices of appeal were filed eleven days late and that the filing of a timely notice of appeal is mandatory and jurisdictional. It relies on the provision of Rule 45(b), Fed.R.Crim.P., 18 U.S.C.A., that “the court may not enlarge * * * the period for taking an appeal.”
Rule 45(b) provides, with respect to acts required or allowed to be done at or within a specified time, that the District Court, for cause shown, may at any time in its discretion do one of two things:
(1) It may “order the period enlarged” if an application for such enlargement is made before expiration of the allowed time.
(2) If the party, as a result of excusable neglect, has failed to act within the allowed time, the court, upon motion, may “permit the act to be done after the expiration of the specified period * *
The rule then states the provision the Government relies on here, namely, that “the court may not enlarge * * the period for taking an appeal.” This injunction upon the District Court applies to enlargement of time, the first of the two causes permitted by the rule. But it does not apply to the second alternative. In other words, the District Court has no authority to grant a greater period than ten days for taking an appeal. It may, however, if satisfied that the failure to note an appeal within ten days is excusable, permit late filing.
There is a sound reason why the District Court should be permitted on limited grounds to extend the time for appeal after its expiration, even though it may not do so before its expiration. There is ample justification in reason for different treatment of pre-expiration and post-expiration applications. While it is, of course, desirable and contemplated that a party who intends to and is able to file a simple notice of appeal should do so within the time prescribed, there is a rational basis for exceptions in exceptional circumstances. If he can make a timely application for an extension of time, he can readily and with less effort file the notice of appeal itself. If, however, for some cause amounting legally to “excusable neglect” the party fails to take any action during the prescribed time, the rule seems plainly to allow the District Court discretion to permit him to file a late notice of appeal.
*720In the cases before us, it appears from the affidavit of appellants’ trial counsel that he informed the court at the sentencing that the appellants intended to appeal and that the only reason the appeals were not taken within ten days, as required by Rule 37(a), Fed.R.Crim.P., was that counsel, who had never taken a criminal appeal before, mistakenly assumed he had thirty days, as provided in Rule 73(a), Fed.R.Civ.P., 28 U.S.C.A.
If, on this showing, the District Court was satisfied that the failure to act within ten days was a result of excusable neglect, we have jurisdiction of the appeals. From the record before us we cannot tell whether or not the District Court intended its grant of the May 28 application as a determination of excusable neglect. We therefore remand the cases to the District Court for supplementation of the record as to whether that court intended its grant to serve as a finding that failure to act was due to excusable neglect under Rule 45(b), Fed.R.Crim.P.
So ordered.
