color. In a few specimens there is an obscure line of lighter 

 brown along the sides, where the ochreous color prevails, and a 

 tinge of the same color on the upper surface of the fore legs above 

 the knees. The feet are light grey ; the tailj for three fourths of 



its length from the root is yellowish brown, then black edged 



with white j the throat, inner surface of the legs and the belly, 

 white. 



This species is common in South Carolina, Alabama, Florida, 

 &c. and is probably not rare as far north as Philadelphia. 



In habits this species differs much from the S. leucoiis. Its 

 bark is less full, and much shriller and more' querulous. Its usual 

 haunts are in low swampy places, and among the trees overhang- 

 ing rivers. It is very active even after dusk, and in moonlit 

 evenings. The young are commonly five or six in number and 

 brought forth in March.
