OPINION
PER CURIAM:


1
Samuel Ojo Adetiba seeks to appeal his criminal conviction and sentence.   Adetiba noted his appeal of his convictions outside the tenday appeal period established by Fed.R.App.P. 4(b) and failed to move for an extension of the appeal period within the additional thirty-day period provided by Fed.R.App.P. 4(b).   The time periods established by Fed.R.App.P. 4 are "mandatory and jurisdictional."   Browder v. Director, Dep't of Corrections, 434 U.S. 257, 264 (1978) (quoting  United States v. Robinson, 361 U.S. 220, 229 (1960)).   Appellant's failure to note a timely appeal deprives this Court of jurisdiction to consider this case.   We therefore deny his motion to appoint counsel and dismiss the appeal.*  We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the Court and argument would not aid the decisional process.


2
DISMISSED.



*
 Adetiba's allegation that his trial counsel failed to perfect a timely appeal could, if true, provide the basis for a collateral attack on his conviction.   See United States v. Reyes, 759 F.2d 351, 353 (4th Cir.), cert. denied, 474 U.S. 857 (1985)
