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, Onychamys. (Illustration 

 facing p. 121.) 



Florida Deer Mouse 



Peromyscus floridanus (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 I 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.
