MEMORANDUM **

Paul Edward Shook, Jr., a federal prisoner, appeals pro se from the district court’s judgment dismissing his 28 U.S.C. § 2241 habeas petition. We have jurisdiction under 28 U.S.C. § 1291, and we affirm.

Shook contends the district court erred by treating his claims of inadequate medical care as arising under Bivens v. Six Unknown Fed. Narcotics Agents, 403 U.S. 388, 91 S.Ct. 1999, 29 L.Ed.2d 619 (1971), rather than section 2241. We disagree. Despite the relief he seeks, Shook’s claims *703 concern the conditions of his confinement and are properly brought under Bivens.

The district court acted within its discretion when it dismissed Shook’s petition without prejudice for failure to comply with the court’s order to file an amended complaint. See Ferdik v. Bonzelet, 963 F.2d 1258, 1260-61 (9th Cir. 1992).

AFFIRMED.
