Before BEAM, HEANEY, and MORRIS SHEPPARD ARNOLD, Circuit Judges.
                           ___________

PER CURIAM.

       Jose Tapia pleaded guilty to conspiring to distribute and possess with intent to
distribute cocaine base, in violation of 21 U.S.C. §§ 841(a)(1) and 846, and the district
court1 sentenced him to 151 months imprisonment and 5 years supervised release.
Tapia’s counsel filed a notice of appeal, and Tapia requested that his counsel be
dismissed and that he be permitted to proceed pro se on appeal. The district court
denied his request, Tapia appealed that denial, and we consolidated the appeals.


      1
      The Honorable Richard G. Kopf, United States District Judge for the District
of Nebraska.
       Tapia’s counsel has filed a brief (which we understand to argue that the district
court erred by failing to sua sponte grant Tapia a downward departure based on his
diminished mental capacity), and has moved to withdraw pursuant to Anders v.
California, 

(1967). In his pro se supplemental brief, Tapia contends that
the government failed to prove that the drug attributed to him was actually crack
cocaine, that the penalty disparity between crack and powder cocaine violates the
Equal Protection Clause, and that his counsel was ineffective.

       None of these arguments were raised below. We conclude that the district court
did not plainly err by not granting Tapia an unrequested downward departure, and did
not plainly err in determining that the drug attributed to Tapia was crack cocaine. See
United States v. Montanye, 

, 192 (8th Cir. 1993) (en banc) (standard of
review). We have consistently rejected the disparity argument Tapia raises, see United
States v. Clary, 

, 712 (8th Cir. 1994) (collecting cases), cert. denied, 

(1995), and his ineffective-assistance-of-counsel claim would be more
appropriately raised in 28 U.S.C. § 2255 proceedings, see United States v. Martin, 

, 771 (8th Cir. 1995). Finally, because Tapia has now had the opportunity to
present his pro se arguments on appeal, we conclude that his appeal of the denial of his
request to proceed pro se on appeal is moot.

       After review of counsel’s Anders brief, along with our independent review of the
record in accordance with Penson v. Ohio, 

(1988), we find no nonfrivolous
issues. Accordingly, we affirm the judgment of the district court, and we grant
counsel’s motion to withdraw.
