Florida Deer Mouse; Oldfield Mouse 
Range. Mississippi Valley, northward to Tennessee. This 
animal overlaps the range of the common  white-footed 
mouse in Tennessee and both occur together, just as the 
latter, and the Canadian species do in the North. 
8. Florida Cotton Mouse. P. gossypinus palmarius Bangs. Paler, 
but dusky ring around the eye, well defined. 
Range. Southern Florida, north to Brevard and Citrus County. 
9. Louisiana Cotton Mouse. P. gossypinus nigriculus Bangs. 
Smaller than any other cotton mouse, colours darker, with 
a broad blackish stripe on the back. 
Range. Bayou region of Louisiana. 
In the West there are many other white-footed mice and 
another allied group known as scorpion mice, Onychomps. 
Florida Deer Mouse 
Peromyscus florvidanus (Chapman) 
Length. 8.60 inches. 
Description. Ears very large, nearly naked, hind feet very large, 
tail relatively short, sparsely haired. Colour bright tawny 
above, with black hairs sprinkled over the back and head, 
a black ring around the eye and black spot at the base of 
the whiskers. Underparts pure white, extreme base of fur 
gray. 
Range. Florida peninsula. 
This is the largest and probably most beautiful eastern Pero- 
myscus and is entirely restricted to Florida. Its size, together 
with its very large ears, will serve to distinguish it at once. 
Mr. Bangs says of this species: ‘‘It lives only in the higher 
sandy ridges where there is plenty of black jack oak and where 
the bare white sand is in places covered by scattered patches 
of scrub palmetto. It is the characteristic small mammal of such 
places commonly known as ‘black jack ridges’ and | have never 
found it elsewhere.” 
Oldfield Mouse 
Peromyscus subgriseus (Chapman) 
Length. 5 inches. 
Description. Smaller than any of the other white-footed mice. 
Cinnamon brown above, very sharply contrasting with the 
pure snowy whit of the lower surface.
