BY SAMUEL N. RHOADS. 



Urooyon ciaereo-argenteus floridanus subsp. nov. Type, yg. ad. $ , No. 1.837, 

 Col. of S. N. Rhoads. Tarpon Springs, Florida. Col. by W. S. Dickinson, 

 Dec. 1894. 



Description. — Smaller than cinereo-argenteus of the Middle States, 

 with relatively shorter hind foot, tail, and ears, and harsher pelage. 

 Skull characters not appreciably different from the typical form. 

 Crown from between eyes (including space between ears and eyes to 

 black malar stripe), upper neck, back, rump, sides, upper surfaces 

 of legs and feet mixed silver-gray, much as in the northern animal. 

 Chin, margin of lips, whisker patch, upper line and tip of tail and 

 an indistinct double stripe reaching from the nose through and under 

 eyes and joining on cheeks, black. Hind ears, sides of neck to fore- 

 legs, broad band across throat and under surface of foreleg rusty 

 brown. Throat and cheek- stripe, from anterior canthus of eye, white. 

 Anterior upper lip adjoining muzzle, brownish-white. Breast, belly, 

 vent, inner surfaces of hams and inner base of fore-legs pale rusty 

 fulvous, a few grayish-white hairs near vent. Soles of feet cinnamon, 

 with dusky borders. 



Measurements (of type, taken from dry skin). — Total length, 900 

 mm. ; hind foot, 125 ; tail vertebra?, 260; ear, from crown, 60 : (Of old, 

 adult topotype; length, 910; foot, 125; tail, 310; ear, 63). Skull- 

 Total length, 114; basilar length, 103; zygomatic expansion, 65; 

 interorbital expansion, 35 ; length of nasals, 41 ; length of mandible, 

 86 ; width of mandible, 33. 



Two specimens, male and female, from the vicinity of Tarpon 

 Springs, one in winter and the other in summer pelage, show such 

 well-marked differences from the Gray Fox of Virginia and the 

 Middle States, I feel no hesitation in considering them sufficient 

 indication that the fox of southern Florida should be separated from 

 the northern animal. 



Besides the difference in dimensions already stated in the descrip- 

 tion, the Florida fox may be recognized by the paleness of the fulvous 

 color of breast and belly and by the almost entire absence of white 

 on these parts so conspicuous in specimens from Virginia and New
