Mejia Island Deermouse (Peromyscus guardia ssp. mejiae)

The Mejia Island Deermouse, described in 1932, was a subspecies of the Guarda Deermouse (Peromyscus guardia Townsend) and was endemic to the tiny Isla Mejía in the Gulf of California, Baja California, Mexico.

This mouse was last recorded in 1973 but disappeared sometimes after that date due to predation by introduced cats and competition by likewise introduced mice and rats. [1]
