Description. Late Pleistocene terrace on the north side of West Anacapa Island, 25 feet above sea level (White 1966).
Discussion. Anacapa Island is the type locality (White 1966). White's diagnosis follows:
Larger than in any living species except species of the subgenus Megadontomys, Peromyscus zarhynchus, and P. nesodytes. Lower cheek teeth similar to those of P. eremicus and P. californicus but of marked larger size. Significantly smaller than P. nesodytes and distinct from P. zarhynchus, and species of P. (Megadontomys) in lacking accessory cusps and lophs in the molars.
