56 CAROLINA GRAY SQUIRREL. 



Body, shorter and less elegant in shape, and not indicating the quickness 

 and vivacity by which S. migratorius is eminently distinguished. 



The ears, which are nearly triangular, are so slightly clothed with hair 

 on their interior surfaces, that they may be said to be nearly naked ; ex- 

 ternally they are sparsely clothed with short "woolly hair, which, how- 

 ever does not extend as far beyond the margins as in other species. 

 Nails shorter and less crooked ; tail, shorter, and without the broad 

 distichous appearance of that of the Northern Gray Squirrel. 



Teeth, light orange ; nails, brown, lightest at the extremities ; whis- 

 kers, black ; on the nose and cheeks, and around the eyes, a slight tinge 

 of rufous gray. 



Fur on the back, for three-fourths of its length, dark plumbeous, suc- 

 ceeded by a slight indication of black, edged with yellowish-brown in 

 some of the hairs, giving it on the surface a dark grayish-yellow tint. 

 In a few specimens there is an obscure shade of light brown along the 

 sides, where the yellowish tint predominates, and a tinge of this colour is 

 observable on the upper surface of the fore-legs, above the knees. Feet, 

 light gray ; tail, for three-fourths of its length from the root yellowish- 

 brown ; the remainder, black, edged with white ; throat, inner surface of 

 the legs, and belly, white. 



This species does not run into varieties, as do the Northern Gray 

 Squirrel, and the Black Squirrel ; the specimens received from Alabama, 

 Florida, and Louisiana, scarcely present a shade of difference from those 

 existing in South Carolina, which we have just described.
