longer than deep, and its posterior margin about midway between 
tip of snout and axilla. Pupil vertical. Upper covering of eye- 
ball rather tough and forming a more or less horizontal upper 
boundary to iris. Greatest depth of eye about 11% in its length. 
Mouth large, gape very slightly convex in profile, with convexity 
superior. Rictus reaches nearly opposite front margin of tym- 
panum. Lips thin, horny or firm and with upper overlapping 
edge of closed mandible. Edge of upper jaw rather trenchant, 
that of lower a little rounded or convex and thicker. When 
viewed below mouth broadly and evenly convex, with more con- 
stricted convexity of upper jaw projecting in front. Front of 
upper jaw as viewed in front with a very slight median marginal 
notch. No mandibular process at symphysis. Along edge of 
upper jaw a cutting-edge made up of minute obsolete teeth and 
this concealed by upper lip. No mandibular cutting-edge. Upper 
buccal fold rather firm and moderately wide. Vomerine teeth 
minute, in 2 small patches, each about half size of internal nostril, 
separated for a space about equal to their own size, and placed a 
little posteriorly in space .between internal nostrils. Tongue 
large, fleshy, its surface minutely papillose, only attached in 
front, behind and sides entirely free, rather broadly ovate and 
its posterior margin with a slight median notch. Internal nares 
large, a trifle further apart than external nostrils, and rather 
elongated transversely. External nostrils small, a little high on 
front side of snout, directed superiorly, and falling a little nearer 
eye than emargination in middle of front of upper jaw. Inter- 
nasal space nearly level and about 1/4 in level and rather firm 
bony interorbital space. Posteriorly interorbital space rather 
convex. Loreal region deep, bevelled or slightly concave on 
surface. ‘I'ympanum distinct, close behind orbit, mostly below, 
ellipsoid, sloping forward till its lower front margin is nearly 
opposite posterior margin of eye, and its width about 1% in its 
own length. Skin of back minutely tuberculous, and on flanks 
slightly more coarsely. Upper surfaces of limbs scarcely 
minutely tuberculous, and nearly smooth like entire under sur- 
face of body. Parotids small, prominent, convex and rather
