Roque Deermouse (Peromyscus maniculatus ssp. cineritius)

This subspecies of the North American Deermouse (Peromyscus maniculatus (Wagner)) was endemic to the Isla San Roque in the Baja California, Mexico.

The island population disappeared due to the introduction of cats, which not only preyed upon the mice but also largely destroyed the seabird colonies.

***

This subspecies is not accepted by all zoologists.
