linensis, thus restricting Sciurus cinereus Linn, to the light color phase of 

 the southern fox squirrel, and it becomes a direct synonym of Stiurutmger 

 Linn., based on the black phase of the same animal from the same locality. 

 The only other name that need be considered at all is Sciurus virginianus 

 of Kerr's Linmeus, 1792. This name was based on the ' Cat Squirrel ' 

 of Pennant's Arctic Zoology, which is an indeterminable animal, said to 

 have a very short tail and to inhabit A 7 irginia, where the planters call it 

 'Cat Squirrel.' As the vernacular name 'Cat Squirrel' is invariably 

 employed in the South for the gray squirrel, it seems likely that the 

 animal in question was nothing more than that species. It may be well 

 to add that Pennant's gray squirrel was a compound animal, including 

 the gray, the southern fox, and perhaps the northern fox squirrels, but 

 referring best to the gray squirrel, as pointed out by Professor Baird in 

 his Mammals of North America in 1857. Professor Baird is the only 

 author to question the standing of Linnaeus' Sciurus cinereus. With his 

 usual acuteness he saw that the name could not apply to the northern fox 

 squirrel, but for some reason he retained it, probably because Le Conte, 

 Bachman, and others had done so.

Geographic distribution. Austral Zone, from northern Florida north to 

 about the lower Hudson Valley, west through the Alleghanies south of 

 Pennsylvania to Indiana, Missouri, Indian Territory, and the edge of the 

 plains. 



Habitat. In the South, where Sciurus carolinensis occurs in the same 

 region with the southern fox squirrel, the two liv in woods of very dif 

 ferent character. The fox squirrel is exclusively an inhabitant of the 

 flat, open ' piney woods.' The gray squirrel lives in the dense hammocks 

 of live oak and water oak, and in the deep swamps of cypress, black 

 gum, and great magnolia that border the streams. Farther north it is 

 found in the forests and groves of oak, chestnut, and hickory. 



Though they feed much on the ground, all the gray squirrels are highly 

 arboreal and very active tree-climbers, springing, when occasion requires 

 it, long distances from branch to branch. 



The southern gray squirrel is in many places exceedingly abundant, 

 but is much shot by the negroes for food, and where persecuted is very 

 shy and seldom seen, passing the greater part of the day in hollows or
