158 Bangs The Squirrels of Eastern North America. 



begins gradually to approach carolinensis typicus, a large series from Acadia 

 Parish, La., showing this tendency. Mr. Rhoads speaks of the living 

 gray squirrels he saw in the park at Memphis, Tenn.,*and refers them to 

 fuliginosus, on account of their large size and dark coloring. They are 

 probably about like the examples from central Louisiana, which retain 

 the large size and dark color above, but have pure white under parts, and 

 can safely be called intermediates between carolinensis and fuliyinosus, 

 though perhaps nearer fuliginosus. 



Specimens examined. Total number, 37, from the following localities: 

 Louisiana: Gibson, Terre Bonne Parish, 13; Cartville, Acadia Parish, 

 3; Point Aux Loups Springs, Acadia Parish, 21. (Those from Acadia 

 Parish not extreme.) 



Sciurus carolinensis extimus subap. nov. Everglade Gray Squirrel. 



Type from Miami, Dade Co., Florida. No. 4519, 9 young adult, collec 

 tion of E. A. and O. Bangs. Collected March 12, 1895, by L. Brownell. 

 Total length, 432; tail vertebrae, 194; hind foot, 54. 



Geographic distribution. Subtropical fauna of south Florida, northward 

 about half way up the peninsula. 



Habitat. Everglades and oak and cabbage palmetto hammocks. Not 

 found in the ' piney woods.' 



General characters. Size smallest of the carolinensis series ; tail and hind 

 foot short; color much lighter, more gray than in carolinensis typicus; 

 soles naked ; ears with sometimes a slight woolly tuft at base. 



Color. Upper parts yellowish gray, the hairs banded black and dull 

 yellow, a few tipped with white (much the same color as the upper parts 

 of leucotis in summer pelage) ; tail light colored, the hairs yellowish at 

 base, then black and tipped with white ; under parts white ; ear tufts 

 white. 



Cranial characters. Skull smaller than that of true carolinensis, other 

 wise similar. Size of an average adult skull, the type : basilar length, 47 ; 

 occipitonasal length, 55; zygomatic breadth, 31.2; greatest height of 

 cranium above palate, 18 ; greatest length of single half of mandible, :>'!. 2. 



Size. Average measurements of seven adult specimens from Miami, 

 Fla. : total length, 438.4 ; tail vertebrae, 190.9 ; hind foot, 47. 



General remarks. Sciurus carolinensis extimus represents in its small size, 

 short tail, and small hind foot the extreme of differentiation of the caro 

 linensis series, but differs widely from true carolinensis, its nearest geo~ 

 graphical cousin, in its much grayer color. This yellowish gray color is 

 probably highly protective, the animal spending most of its life among 

 trees covered with the gray Spanish moss, Tillandsia usneoides, which its 

 color almost exactly matches in tone. 



S. carolinensis extimus is only typical in the peculiar subtropical fauna of 

 the everglades and southern part of the Florida peninsula. Specimens 

 from Citrus Co., Fla., are larger and darker in color and are rather nearer 

 to true carolinensis than to extimas. The gray squirrel of northern Florida 

 is true carolinensis.
