U. 8. P. R. R. EXP. AND SURVEYS——ZOOLOGY—-GENERAL REPORT. 
The first binomial name applied to this species was, unquestionably, that of S. niger, of 
Linnaeus, based on the u black squirrel of Catesby, from Carolina, with white nose and ears. 
As, however, the term applies only to a sing-le stage of coloration, and not even to a particular 
or permanent variety, it cannot be retained. The name next in order is S. vulpinus of Gmelin, 
a translation of its generally received vernacular appellation. 
The gray squirrel of Catesby and Pennant may be inserted here, although usually ranged 
under S. cinereus; the descriptions are, however, so vague as to apply almost equally well to 
either. 
The Sciurus texianus, of Bachman, is stated by its author, North American Quadrupeds, III, 
344, to be a variety of S. vulpinus. The locality of Mexico, as originally given, is probably 
erroneous, unless the specimen in the Paris museum may have come from northeastern Texas, 
then part of Mexico. I am not aware that the S. vulpnius is found west of Louisiana, nor 
does it appear to reach far from the Gulf of Mexico to the north. I have seen no specimens from 
north of North Carolina. The Sciurus variegatus of some authors belongs here. 
This fox squirrel is found as far north as North Carolina, possibly as far as the Great Dismal 
Swamp. It occurs throughout Georgia, Florida, and the Gulf States, but is said not to extend 
beyond the Brazos river of Texas.
