BANGS : LAND MAMMALS OF FLORIDA AND GEORGIA. 193 
brownish white, usually suffused with dull cinnamon; tail indis¬ 
tinctly bicolored, black above, dusky gray below; feet and hands 
dusky, sometimes slightly brownish ; ears sparsely haired, dusky. 
Cranial characters. Skull similar to that of 8. hispidus hispi- 
dus or S. hispidus littoralis but decidedly smaller, molar teeth 
smaller. 
Measurements. The type, 9 old adult: total length, 263.5 ; tail 
vertebrae, 98.7; hind foot, 30.4; average of the six largest adults, 
males and females, from Flamingo, Florida: total length, 267.31; 
tail vertebrae, 100.4; hind foot, 31.33. Largest specimen, $ old 
adult, No. 4,486 from Flamingo: total length, 279.4; tail vertebrae, 
108.1; hind foot, 31.9. (8. hispidus hispidus and 8. hispidus 
littoralis are of about the same size, the latter perhaps averaging a 
trifle the larger, and old adults often exceed 300 m. in total length. 
The largest specimen measured is No. 3,351, 9 old adult, topotype 
of 8. hispidus littoralis, total length, 330; tail vertebrae, 113 ; hind 
foot, 34.) 
General remarks. 8. hispidus spadicipygus is the form Mr. 
Chapman mentioned in his list of the land mammals of Florida, 
where he pointed out some of its characters, but considered it not 
worthy of separation. His specimens were from Flamingo. It 
seems to me a too strongly marked race to remain without name. 
Mr. C. L. Brownell collected for me, in the spring of 1895, seven 
specimens at Cape Sable and thirteen at Flamingo. 
8. hispidus spadicipygus is confined to the extreme tropical point 
of south Florida, ranging on the east north nearly to Miami, where 
it passes rather abruptly into 8. hispidus littoralis, and on the west 
probably to about Tampa Bay, where it shades more gradually into 
8. hispidus hispidus. It differs from 8. littoralis in being much 
browner and less gray and in the cinnamon-rufous color of the rump, 
but agrees with that form in the fine markings of the upper parts. 
From 8. hispidus hispidus it differs in much finer markings of upper 
parts with greater predominance of black, in the color of the rump, 
and in having a less distinctly bicolored tail and darker feet and 
hands. From both it differs in being much smaller.
