¶1Lawrence Crawford seeks to appeal the magistrate judge’s order denying his motion to add new defendants to his 42 U.S.C. § 1983 (2000) civil rights action. This court may exercise jurisdiction only over final orders, 28 U.S.C. § 1291 (2000), and certain interlocutory and collateral orders. 28 U.S.C. § 1292 (2000); Fed. R.Civ.P. 54(b); Cohen v. Beneficial Indus. Loan Corp., 337 U.S. 541, 545-47, 69 S.Ct. 1221, 93 L.Ed. 1528 (1949). The order *171Crawford seeks to appeal is neither a final order nor an appealable interlocutory or collateral order. Accordingly, we dismiss the appeal for lack of jurisdiction. Further, we deny Crawford’s motion for clarification regarding what issues are before this court. 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.
¶2DISMISSED.
