elongate, slender and cylindrical. Surface all rounded, smooth, 
and especially convex. ‘Trunk not especially swollen, though 
largely cylindrical. Costal grooves 19, counting axillary and 
inguinal. About 4 pelvic grooves. No scapular groove between 
gular fold and axillary groove. About 36 grooves on side of 
tail, most distinct towards base and obsolete towards tip. 
Grooves also more or less obsolete or fading out altogether on 
middle areas of back and abdomen. No keel along upper side of 
body. None of grooves on tail joined to their fellows on its 
lower surface. No distinct groove longitudinally on entire upper 
surface or lower surface, tail being perfectly convex. Tail cylin- 
drical in cross-section, only very slightly compressed towards its 
tip, which is slenderly acuminate. Head rather small, broad, 
depressed both above and below, its width about equal to great- 
est of body, obtuse in profile and its angle forming a little low in 
depth. Snout about twice as broad as long, projecting much 
beyond closed mandible, and broadly convex when viewed from 
above. Eye a little elongate, ellipsoid, well elevated, small, and 
placed near first third in length of head. Eyelids fleshy and well 
developed. Pupil circular. Mouth broad, and when viewed from 
below seen to be more evenly convex than broader upper pro- 
jecting edge of snout or upper jaw. Lips thin, little developed, 
and firm. Postrictal transverse or vertical groove obsolete. A 
similar second postrictal transverse groove between it and gular 
fold, which follows. Gular groove or fold well developed, not 
passing over nape, though overlapping on neck below. From 
eye to shoulder a slight ridge extends back and joins all grooves 
in course mentioned. Neck a little constricted, though parotid 
region not quite swollen to width of skull. Teeth in jaws in a 
single even series, small and not especially numerous. Palatine 
teeth minute, arranged in 2 small patches convergent backwards, 
though separated. ‘Tongue large, rounded, though a little longer 
than deep, and with spongy plicated surface. Internal nares 
would fall within bony interorbital space, and each not far from 
middle of length of each band of palatine teeth. Exterior nos- 
trils close along front edge of snout, and also falling within limits 
of bony interorbital width. Internasal space convex, and inter-
