 with the heel. There are two plantar tubercles. The internal is nar- 

 row, rather prominent, and with obtuse extremity ; the other is at the 

 base of the tburth n)etatarsal bone, and is rounch'd. 



The muzzle is obtuse and the head rather wide. Its <rreatest width 

 nt the position of the membranuni tympani equals the len^tii from tlie 

 end of the muzzle to the line conneetinjj the axilhe in sonu' specimens; 

 in others to that connectiiifj the middle of the humeri. The skin is on 

 Jill the superior surfaces thick and j;laiulular. This condition is espe. 

 cially nujrked in the dorsolateral fold of each side, which is so thickened 

 in front as to resemble a paratoid {^land. This becomes less visible in 

 alcohol. The tympanic inenduane is either entirely concealed or is rep- 

 resented by a dei)ression only. The skin (toveriufj- it is rou^heiu'd. A 

 •jroove extends downwards and backwards from it. JJetweeu this and 

 the canthusovis is a <flandular thickeninji-, and behind it are two others, 

 one above the other. I'osterior to these, on the sitles, is a succession of 

 rounded, r» ut;;hened warts, similar to those on the toads. Similar waits, 

 but less promiiu'iit, are .scattered over the dorsal region, ami are numer- 

 ous near the extremity of »he co:cyx. The skin of the sujierior surfaces 

 of the liead, body, and lindis is minutely but very distinctly roughened 

 by small warts, each of which gives exit to a pore. Inferior surfaces 

 smooth. Length of fingers, beginning with the shortest, 1, L', 4, .'{. 



Tile color is dark brown or nearly black, with indistinct <larker spots 

 on the itack ; sides lirowii. Axilla and gr(»iii yellow, marbled with black. 

 Thighs above light or dark brown, with lliree darker cross-ltars. Tiiiiic

 near the coast of ('a 11 torn ia. That species has but one palmar liilieiele. 

 tin- internal, which is of similar proportions to that of the A*. /«>(///'/. 

 i'lie skill is not thickened, and is iinieji less glandular everywhere. Tiie 

 iih'mi)iaiiiiiM tympani is entirely distinct, i'he posterior faceol'the femur 

 is not vermiciilated with yellow, but is covered with large black masses. 

 The whole of tlu' under surfaces are brown spotted. There are tour 

 brown cross bars on the tibia; traces of the fourth sometimes appear in 

 the /»'. hni/lii. From Ik'tant prvtinsa it dilVers in all tliesi' characters, 

 besides those that belong to the latter; /. c, the fasciculated vomerine 

 teeth and the short hind legs.
