IJody (l('presso<l,el()n};at('(l ; limbs I'loiijjiitifd and well dcvoloped ; head 

 broad, acuto, rounded anteriorly; no.strils elonj^ated, situated below 

 the crest of the eauthus rostralis, half-way below the eye and tip of 

 snout; eye moderate, contained three times in theehord of tiieconiaiis- 

 sure, situated two-thirds of it8 diameter from the rictus ; tympanum 

 small, but Mttle more than half the diameter of the eye. Inner nares 

 rather elonjjated transversely. The vomerine teeth very few in each 

 patch; the patches quite small, somewhat elliptical, and inclined hiw.k- 

 wards, where they are separated by an interval a little less than that 

 between the anterior e.xtremities and nares; tlie.se extremities are in 

 a line with the centers of the nares, but the teeth are on the posterior 

 niar;;ins ; the ])rotuberances are decidedly posterior to the nares. 

 Tonj^ue small, narrow. ICustaeliian openin;;s larj;e. 



The skin is everywhere free from asperities, but not smooth, and on 

 an att<'ntive examination is .seen to lie minutely pitted all over, and 

 with coarser indentation on tlie upper surfaces of the limbs, the sides 

 of the face, and alon^- tliedors;il fold, which aiipearsciuite porous. The 

 buttocks are much j;raiiiilatt(l. ;. ilmiacter wliicii appears to extend a 

 little on the abdomen and sides. .V liroad depres.seci fold of skin extends 

 from tlu' eye to the bind lej;s. This is distinctly perforated or porous 

 tlirou;;iiout its extent. There are no intermediate ridges; a j^hunbilar 

 lu'olonjiatmn of upper jaw to the arm, interrupted at the posterior ex-

 broad. I'ourth toe much the lonj;est, ami with the last two. joint.s en- 

 tirely free, as are the terminal joints of all the toi's. The third joint 

 of the lonj^est toe has a very s!ij,dit margin, diminisliiuf? to the .second 

 articulation, and the inner sides of tiu' third and .second toes are 

 scarcely, if at all, nuirfiined. Cuneiform process small, soft; no other 

 tulterdes on the sole, and .scarcely any indications of any under the 

 joints.
