86 SCAPHIOPUSSOLITARIUS. 



The back is yellowish-green, clouded with dark brown blotches, and covered 

 with small warts of different sizes; many of these are of a dark brown colour; 

 others, reddish or orange. Two decurved lines of pale yellow extend from the 

 orbits to the vent; on each flank is another line of the same colour, but less distinct 

 and shorter, reaching only from the shoulder to the thigh. The inferior surface 

 of the throat is yellowish white; the abdomen dirty white, and granulated pos- 

 teriorly. 



The anterior extremities are long; their colour yellowish-green, clouded with 

 a few blotches of brown on the upper surface, — a reddish tinge on the lower, 

 approaching to flesh colour. The fingers are four in number, short and distinct. 

 The male is distinguished by having the two inner ones black above. The pos- 

 terior extremities are short, but very muscular, and have the leg conspicuously 

 shorter than the tliigh; they are yellowish-green on the upper surface, marked 

 with a few blotches and transverse bands of dark brown, and sometimes with a few 

 small reddish spots. The lower surface of the thighs is flesh colour, and granulated. 

 The toes are five in number, and distinctly palmated. On the internal margin of 

 the metatarsus is a horny spade-like process, containing a bone, which moves by 

 an imperfect joint: the breadth of this process is about a line and a half, its length 

 one line; the cutting edge is jet black. 



The skin is very delicate; and though warty after long exposure, when first 

 taken from its hole the Scaphiopus presents the etiolated appearance of a genuine 

 subterraneous animal. 



Dimensions. Length of body, 2i inches; of the thigh, rather less than an inch; 

 of the leg, f of an inch; of the tarsus and toes, l^ inches; of the forearm, with 

 carpus and fingers, nearly an inch. 



Geographical Distribution. Its range is more extended than I at first appre- 

 hended. It is found in Carolina and Georgia, and Dr. Troost has sent me a speci- 

 men from Tennessee.
