white ; in front and at the tips of the ears they are ochry ; in the winter 

 the fur is about half an inch longer than the tips of the ears, forming a 

 kind of pencil ; in summer these hairs are short and adpressed both on 

 the ears and round the eyes, giving these parts rather a light ash-colour 

 than pure whlte.f 



This Squirrel is not common in the district. I have seen them in 

 New York, and a grey Squirrel is said to be more common in the 

 more southern settlements of Canada, and to be very like that which I 

 have described. The size of the Sciurus magnicaudatus, as given by 

 authors, is very different, as well as the proportion of the body and tail, 

 and the fur of the only specimen of the Carolina Squirrels which I have 

 seen, is very unlike this, and the ears are of the .same colour as the back.

 For the representation of the five new species of Mammalia, described 

 in the preceding paper, the proprietors have to acknowledge their 

 obhgations to Dr. Capper who has kindly given to them the use of

The attention of naturalists having been recently drawn to the general 

 subject of systematic classification, the editors of the Zoological Journal 



f " This animal seems to belong to some of the varieties, as they have been 

 " termed, of the Sciurus cinereus, but I think the shape of its ears is a sufficient 

 " mark to distinguish it from the live ones in the Zoological Museum. — J. R."
