SCIURIDA—SCIURUS CAROLINENSIS—SYNONYMY. 709 
writers have, notwithstanding, applied the name cinereus to the present spe- 
cies. According to Professor Baird, Ord, in 1815, gave the name pennsyl- 
vanicus to the black variety of the Gray Squirrel, though Godman* and subse- 
quent authors have often applied to it the name niger, long previously given by 
Linnzeus to the black phase of the Fox Squirrel. Gapper, in 1830, gave the 
name /eucotis to Canadian specimens of the common gray form. This name 
I adopt for the northern variety, from its being exclusively applicable to the 
northern form. While pennsylvanicus of Ord has fifteen years’ priority over 
this name, it was given to specimens from the Middle Atlantic States, and 
hence from a locality bordering upon the habitat of the southern form, and con- 
sequently the name is not strictly applicable to the northern type as devel- 
oped in the Northern and Northeastern States and the Canadas. Audubon 
and Bachman, not liking the name dewcotis of Gapper, proposed, some twenty 
years later, to substitute for it the name mégratorius as being one far more 
appropriate for the Northern Gray Squirrel. Dr. Bachman had previously 
regarded the Northern and Southern Gray Squirrels as distinct species, 
restricting the name carolinensis to the southern form. The name fuliginosus 
of Bachman apparently refers to a dusky phase of the southern form, sup- 
posed by him to be more or less common along the lower part of the Mis- 
sissippi, especially in Louisiana. I have met thus far with uo melanistic 
specimens of the Gray Squirrel from any point south of Pennsylvania, nor 
have I found any other reference to anything that can be considered as a 
melanistic phase of the southern variety. The specimens from New Leon, 
Mexico, referred very doubtfully by Professor Baird to Scturus carolinensis, 
seem not to be varietally distinguishable from the southern form of this spe- 
cies, and are hence here identified as referable to var. carolinensis. 
The Sciurus carolinensis of De Saussure from Mexico seems not to 
differ materially from S. carolinensis of the United States. ‘Cauda corpore 
vix brevior. Supra fuscus, flavo dense tessellatus; dorso medio obscuriore, 
lateribus flavescentibus”, ete., applies unequivocally to S. carolinensis, and to 
no other species thus far known to me. Tomes gives it from Duenas, Guate- 
* Richardson (Faun.-Bor. Amer. i, 191) cites “ Sciurus niger Say, Long’s Expedition, vol. i, p. 262”, 
probably from the English edition, which is the one he elsewhere says he usually quotes. In the Amer- 
ican edition, in the “Catalogue of the Names of Animals” met with at and on the journey to Engiveer 
Cantonment (vol. i, p. 376), occurs “ Sciwrus nigra—Black Squirrel”, but with no further remarks, and 
hence nothing to indicate the locality of its occurrence, or whether the “ Black Squirrel” here referred to 
is S. carolinensis or a melanistic phase of one of the Fox Squirrels. In the same manner are mentioned 
“Sciurus capistratus” and “ Sciurus cinereus”.
