"This has been to me a rare species. It is said to be common 

 in the oak and hickory woods of Pennsylvania, and I have occa- 

 sionally met with it near Easton and York. I also observed one 

 in the hands of a gunner near Fredericksburg, Virginia. In the 

 northern part of New York it is exceedingly rare, as I only saw two 

 pair during fifteen years of close observation. In the lower part of 

 that statė, however, it appears to be more common, as I recently re- 

 ceived several specimens procured in the county of Orange. 



" This sąuirrel has many habits in common with other species, 

 residing in the hollows of trees, building in summer its nešt of 

 leaves in some convenient crutch, and subsisting on the šame va- 

 riety of food. It is, however, the most inactive of all our known 

 species. It mounts a tree, not ■vvith the lightness and agility of the 

 Northern Gray Sąuirrel, but with the slowness and apparent reluc- 

 tance of the little Striped Sąuirrel {Tamias Lysteri). After ascend- 

 ing, it does not mount to the top, as is the case "vvith other species, 

 but clings to the body of the tree on the side opposite to you, or 

 tries to conceal itself behind the first convenient limb. I have never 

 observed it escaping from branch to branch. When it is induced in 

 search of food to proceed to the extremity of a limb, it movės cau- 

 tiously and heavily, and returns the šame Mvay. On the ground it 

 runs clumsily and makes slovi^er progress than the Gray Sąuirrel. 

 lt is usually fat, espeoially in autumn, and the flesh is said to be 

 preferable to that of any other of our species. 



" The Cat Sąuirrel does not appear to be migratory in its habits. 

 The šame pair, if undisturbed, may be found taking up their resi- 

 sidence in a particular vicinity for a number of years in succession, 

 and the sexes seem mated for life."

Dr. Bachman statės, that this species, which is very common in 

 the northern and middle statės, has hitherto been improperly con- 

 founded with the Carolina Gray Sąuirrel. It appears to have the 

 additional anterior molares permanent, in this particular agreein^
