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 vertebra, 
5.15 in. (130 mm.); hind foot, 1.87 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 loguax, as are all other Wisconsin and Michigan speci- 
mens which I have so far examined.
