A second specimen, the locality of which was not given, differed 

 from the above in having a much richer colouring. The belly was 

 of a very bright rust colour. The hairs on the tail were black at the 

 roots, then broadly annulated with rusty yellow, then a considerable 

 space occupied by black, the apical portion white, but when 

 viewed from beneath, a bright rust colour like that of the belly was 

 very conspicuous, occupying the basal half of the hair. The upper 

 parts of the body were grizzled with black and white, and many of 

 the hairs were annulated with rust colour. Over the haunches and 

 rump, the hairs are annulated with rusty yellow and black. The 

 hairs of the feet were chiefly black. 



The original specimen on which this species was founded, is in 

 the Museum at Paris, and Dr. Bachman quotes the following de- 

 scription from Mr. Waterhouse's manuscript notes. 



" General colour, grizzled black and white. Throat, chest, belly, 

 innerside of legs, nearly the whole of the fore-legs, and the forepart 

 of the hind-legs, rusty red. Tail very broad ; the hairs black ; red 

 at the base, and white at the apex ; lips white ; feet black, with a 

 few white hairs intermixed ; forepart of head also black, with scat- 

 tered white hairs. Chin blackish in front, shading towards tlie 

 throat into gray."

Of this species Dr. Bachman remarks, " It has sometimes been 

 confounded with the Fox Squirrel, and at other times with the 

 Northern Gray Squirrel. It is, however, in size intermediate be- 

 tween the two, and has some distinctive marks by which it may 

 always be known from either. The Northern Gray Squirrel has, as 

 far as I have been able to ascertain from an examination of many 

 specimens, permanently five grinders in each upper jaw, and the 

 present species has but four. Whether at a very early age the Cat 

 Squirrel may not, like the young Fox Squirrel, have a small deci- 

 duous tooth, I have had no means of ascertaining; all the specimens 

 before me, having been obtained in autumn or winter and being 

 adults, present the dental formula as given above. The Fox Squirrel 

 is permanently marked with white ears and nose, which is not the
