Rostro-dorsal profile convex. Height somewhat more than 

 length of head and 3.6—4 times in length and more or less 

 than 5 times in length with caudal. Eye 3.6 — 3.8 in length 

 of head and about twice the length of postorbital part ; gela- 

 tinous membrane well developed, posteriorly covering the iris 

 totally or nearly so. Interorbital space convex, nearly twice 

 the length of the head. Snout convex, blunt, about equal to the 

 diameter of eye. Praeorbital not or only slightly emarginate, 

 conspicuously denticulate and squamate. Maxillary hidden when 

 mouth is closed. Upper lip rather thick. Symphysial knob 

 double. Origin of first dorsal slightly nearer to snout than to 

 base of caudal or midway between them; opposite to I2tli — 14th 

 lateral scale, separated by 18 — 19 praedorsal scales from snout. 

 Dorsal spines moderate, with a long axillary scale below their 

 base, lower than second dorsal and anal, which are emarginate 

 and thickly covered by scales. Origin of second dorsal oppo- 

 site to 2ist — 24th kiteral scale, behind origin of anal, which is
