grooves obsolete. Grooves on tail rather obsolete, mostly notice- 
able below anteriorly, and others fading out behind. ‘Tail thick, 
somewhat oval in cross-section with bulge above, surface smooth, 
convex and without any indication of keel. Base of tail nearly 
cylindrical, though lower surface becoming compressed towards 
tip, which is pointed. Lateral groove on tail obsolete. Head 
broad, flattened or depressed below, and convex above. Profile 
rather obtuse in front. Snout twice as broad as long, projecting 
a little beyond mandible, and broadly convex when viewed above. 
Eye a little elongate, or ellipsoid, of moderate size, elevated, and 
placed near first 24 in length of head. Eyelids fleshy and well 
developed. Pupil circular. Mouth broad, its profile when viewed 
from below similar to that of snout as seen from above. Lips 
rather firm, little developed. A slight vertical constriction behind 
angle of mouth made up of 2 vertical grooves, first close to rictus 
and second or posterior just in front of shoulder, and these united 
by a connecting horizontal groove on side. ‘Teeth minute, uni- 
serial and numerous along edges of jaws. ‘Teeth on roof of 
mouth forming 3 patches transversely of a single series each, 
median much larger than each small lateral patch, which is 
separated from either end by a decided interval, and somewhat 
double-lunate in shape, with convexities facing down throat. 
Lateral patch about %4 length of median. Tongue large, broadly 
ellipsoid, fleshy, largely filling mouth, and surface finely plicated. 
Interior nares just before each lateral patch of teeth on roof of 
mouth. Exterior nostrils near front edge of snout, inconspicu- 
ous, rather small, and space between about equal to bony inter- 
orbital space. Both interorbital and internasal regions rather 
evenly though slightly convex. Skin perfectly smooth, under a 
lens showing minute simple pores everywhere, except to some 
extent on lower surface. These pits or pores apparently connected 
with glands. No regular patches of more conspicuous ones on 
head and parotids. Fore limb inserted at first fifth of body, and 
reaches */, of space to hind limb. Digits linear, rather elongately 
conical, depressed basally, and without web or margin. ‘Third 
finger longest, 3 in rest of arm, first and fourth shortest and 
subequal. Hind limb inserted a little nearer tip of snout than 
tip of tail, and reaching % to latter. Fourth toe longest, about
