June 14, 1999







                                

                                









            Per Curiam.  Upon careful review of the briefs and

  record, we conclude that the district court did not clearly err

  in sentencing defendant based on the drug quantity to which he

  specifically pled guilty.  Given defendant's plain admissions

  at the plea hearing and the lack of a developed challenge to

  the validity of the plea, defendant will not now be heard to

  argue about the drug quantity.  See United States v. Martinez-

  Martinez, 69 F.3d 1215, 1224 (1st Cir. 1995).  The district

  court was not required, on the record before it, to adopt

  defendant's revised, post-plea version of his involvement with

  the drug shipment.

            Affirmed.  See 1st Cir. Loc. R. 27.1.
