Mary J. Wills petitions for review of a final order of the Benefits Review Board (Board) denying her application for black lung benefits as the surviving spouse of John A. Wills pursuant to Title IV of the Federal Coal Mine Health and Safety Act of 1969, as amended, 30 U.S.C. § 901 et seq.

The Director, Office of Workers' Compensation Programs, has filed a motion to dismiss for lack of jurisdiction because the appeal was not filed within sixty days of the decision and order of the Board. Westmoreland Coal Company has joined in the motion for dismissal of the appeal.

The timely filing of a petition for review of an order of the Board with a Court of Appeals within sixty days is a jurisdictional prerequisite. See Butcher v. Big Mountain Coal, Inc., 802 F.2d 1506, 1508 (4th Cir. 1986); 33 U.S.C. § 921(c); 30 U.S.C. § 932(a). Because Wills filed a petition for review on January 25, 1989, more than sixty days after the Board's order on reconsideration of November 21, 1988, it was untimely, and this Court is without jurisdiction to consider the appeal.

Accordingly, although we grant leave to proceed in forma pauperis, we dismiss the appeal. We dispense with oral argument because the dispositive issues recently have been decided authoritatively.

DISMISSED.
