                            Appeal from the United States District Court
                                 for the Western District of Texas
                                USDC No. A-94-CR-190-ALL-SS
                                         --------------------
                                          March 1, 2002

Before JONES, SMITH, and EMILIO M. GARZA, Circuit Judges.

PER CURIAM:*

         Billy Ray Fitzgerald appeals the district court’s denial of his 18 U.S.C. § 3582(c)(2) motion

to reduce his 210-month prison sentence for possessing more than five grams of cocaine base. The

district court may modify a defendant’s term of imprisonment “in the case of a defendant who has

been sentenced to a term of imprisonment based on a sentencing range that has subsequently been

lowered by the Sentencing Commission pursuant to 28 U.S.C. [§] 994(o).” 18 U.S.C. § 3582(c)(2).



         *
          Pursuant to 5TH CIR. R. 47.5, the court has determined that this opinion should not be
published and is not precedent except under the limited circumstances set forth in 5TH CIR.
R. 47.5.4.
                                             No. 01-50727
                                                  -2-

This court reviews the district court’s determination whether to reduce a sentence pursuant to 18

U.S.C. § 3582(c)(2) for abuse of discretion. See United States v. Pardue, 

, 430 (5th Cir.

1994).

         On appeal, Fitzgerald renews his claims that his sentence is unconstitutional under Apprendi

v. New Jersey, 

(2000), and that the sentencing court erred in converting a sum of cash

into drugs for its drug quantity determination. Fitzgerald, however, has not identified any amendment

to the Sentencing Guidelines with regard to either of these claims. The district court thus lacked

authority to reduce Fitzgerald’s sentence pursuant to 18 U.S.C. § 3582(c)(2). See United States v.

Lopez, 

, 515 & n.3 (5th Cir. 1994).

         Fitzgerald also argues for the first time on appeal that the sentencing court did not follow the

requirements of FED. R. CRIM. P. 32 in addressing his objections to the presentence report and in

making erroneous factual findings at sentencing; the Government failed to give notice of its intention

to enhance his sentence based on prior convictions; the Government failed to demonstrate that he

possessed “crack” as defined in U.S.S.G. § 2D1.1(c), as amended by Amendment 487; and the trial

court failed to instruct the jury on the lesser included offense of simple possession. Because

Fitzgerald did not assert these claims in the district court, this court will not consider them. See

.

         Because the district court did not abuse its discretion in denying Fitzgerald’s 18 U.S.C. §

3582(c)(2) motion, the judgment of the district court is AFFIRMED. See
