Peromyscus sitkensis Merriam, 1897 . Proc. Biol. Soc. Washington, 11:223.

TYPE LOCALITY: USA, Alaska, Baranof Island, Sitka .

DISTRIBUTION: Outer islands of Alexander Archipelago, off Alaskan panhandle, USA.

SYNONYMS: oceanicus.

COMMENTS: Banded karyotypes reported by Pengilly et al. (1983). Insular forms off southern British Columbia referred to sitkensis by Thomas (1973) but identified as P. oreas by Gunn and Greenbaum (1986). These studies underscore the need to refine relationships among P. sitkensis, P. oreas, and certain forms of P. maniculatus . P. maniculatus species group.
