A.H. Howell, 1939The Chadwick Beach Cotton Mouse (Peromyscus gossypinus restrictus) is a presumed extinct subspecies of the Cotton Mouse (Peromyscus gossypinus) from the genus Peromyscus. It was confined to a small area on the Manasota Key peninsula in Florida.

Description
The Chadwick Beach Cotton Mouse was smaller and paler than the nominate race. The total length was 172 mm, the tail length 72.5 mm, the hind foot length 22.3 mm, the ear length 22.3 mm and largest skull length was 27.6 mm. The zygomatic breadth was 13.9 mm, the preorbital breadth was 4.4 mm, the nasal length was 10.9 mm and the length of the teeth in the maxilla was 3.9 mm. The upperparts were pink cinnamon with a rufous hue in the middle of the back. The underparts were white with a pale pink buff wash on the chest. The tail was brown above and buff below. The dorsal stripe in the middle of the back was smaller than in the nominate race.
Distribution
The mouse was primarily found in the Chadwick Beach area at Englewood in Sarasota County and Englewood Beach located in the southern part of Englewood, Florida in Charlotte County.
Habitat and ecology
The Chadwick Beach Cotton Mouse preferred maritime forests with a closed canopy. Characteristic trees of these forests are Sabal palmetto, Quercus virginiana, and Juniperus virginiana var. silicicola. It was also found on sand dunes where sea oats (Uniola paniculata) a high growing grass species is the dominating vegetation. Like the nominate race the Chadwick Beach Cotton Mouse was nocturnal. The ecology of this subspecies is not studied.
Extinction
The Chadwick Beach Cotton Mouse is only known by 15 specimens collected by Luther C. Goldman in March 1938. It is now presumed extinct after extensive surveys in 1984, 1985, 1988 and 1989 failed to find this mouse again. Causes for its disappearance might have been the deforestion of the maritime forests in the southernmost of the Sarasota County as well as the predation by feral cats.
