 LISTER, Bull. Wis. Nat. Hist. Soc., VI, 1908, p. 138. 



Type locality Liberty Hill, New London Co., Connecticut. 



Distribution Eastern United States from the edge of the plains to 

 the Atlantic coast, and from southern Maine, northern Michigan 

 and Minnesota southward; northern Illinois, northern Indiana, 

 Pennsylvania, and in the mountains south to North Carolina. 

 Replaced in the North and Northeast by allied races. 



Special characters General color (in summer) reddish brown ; under 

 parts whitish, or grayish white, the hairs not vermiculated. In 

 winter olive grayish on sides, with wide brownish red or rufous 

 stripe down the back; tail flattened; ears 'with tufts and soles of 

 feet furred in winter. 



Description In summer: Upper parts reddish brown ; a black stripe 

 on sides separating the red brown color of back from the white on 

 the under parts; under parts white, often tinged in places with 

 rusty; tail largely deep rufous brown; the terminal hairs black near 

 the tip; front of fore legs and upper surface of hind feet clear fer- 

 rugineous. 



In winter: A broad dorsal band of bright rufous brown ex- 

 tending from between the ears down the middle of the back and 

 along upper surface of tail; sides olive gray; no black stripe on 

 sides or but faintly indicated; under parts grayish white, the hairs 

 plumbeous at the base; under surface of tail olivaceous gray, the 

 hairs on sides and end of tail subterminally marked with black and 

 tipped with tawny. 



Measurements Total length, about 12.50 in. (318 mm.) ; tail vertebras, 

 5.15 in. (130 mm.); hind foot, nSy in. (48 mm.). 



Remarks Judging from the material examined, I am inclined to believe 

 the Minnesota Squirrel, S. h. minnesota, to be inseparable from 

 loquax. The color differences, if any, are inconstant and at most 

 would seem to represent intergradation between true hudsonicus 

 and loquax. Some Minnesota specimens are larger than any I 

 have seen from Wisconsin or Michigan, and Minnesota specimens 

 average larger, but the difference in size alone is apparently not 

 sufficiently constant nor sufficiently great to warrant subspecific 

 recognition. Be that as it may, specimens from Solon Springs, 

 Douglas County, in extreme northwestern Wisconsin are certainly 

 referable to loquax, as are all other Wisconsin and Michigan speci- 

 mens which I have so far examined.
