Map showing approximate distribution of Gray Squirrels in eastern United States. 

 In the areas indicated by the dotted spaces between the ranges given for the different races either 

 or both may occur, together with intermediate forms. 



Sciurus caroUnensis Gmel. Type locality — Carolina. Description as previously 

 given. 



Sciurus c. leucotis (Gapper). Type locality — Region between York and Lake 

 Simcoe, Ontario, Canada. Description as previously given. 



Sciurus c. hypophaeus Merriam. (Science, VII, 1886, p. 351.) Type locality — 

 Elk River, Minnesota. Supposed to differ from leucotis in being somewhat 

 darker, and white on under parts restricted to a narrow central streak on the 

 belly. Minnesota Gray Squirrels average somewhat larger, but the color differ- 

 ences are apparently of little value. 



Sciurus c. fuliginosus (Bachman). (Proc. Zool. Soc. Lond., 1838, p. 97.) Type 

 locality — New Orleans, Louisiana. Larger and darker than caroUnensis; under 

 parts never pure white, usually washed with ferrugineous. 



Sciurus c. extimus Bangs. (Proc. Biol. Soc. Wash., X, 1896, p. 158.) Type lo- 

 cality — Miami, Dade Co., Florida. Smallest of our Gray Squirrels; total length 

 (including tail vertebrae) about 17.50 inches; color lighter and more gray than 

 caroUnensis.
