Rostro-dorsal profile slightly convex or rather steep. Height 

 more than head, which goes less than 4 — 4'/., times in length 

 and less than 5'/2 times in length with caudal. Eye without 

 gelatinous eyelid, 3 to 372 in head and twice in its postorbital 

 part. Interorbital space nearly flat and nearly half length of 

 head. Praeorbital bone bent and emarginate, its end broadened, 

 truncate and finely serrated, getting more straight and obliquely 

 descending and less notched in old specimens. Extremity of 

 maxillary visible behind praeorbital, getting hidden when 

 mouth is closed in very aged individuals. Also the lips change 

 with age in fullgrown and medium sized individuals, the upper 

 lip is very thick and high, forming the frontborder of the 

 blunt snout. Near its lower margin a shallow rim or groove is 

 more or less conspicuous, provided with generally one row of 

 more or less pointed papillae, decreasing with age. Lower lip 

 without papillae, its symphysial knob rather high and about 

 double. Least height of caudal peduncle about twice in head. 

 Origin of spinous dorsal, separated by about 20 scales from 

 snout, about midway between end of snout and base of caudal or 

 nearer to caudal, opposite to ii^h — 12th lateral scale. Its spines 

 of moderate strength, longer than postorbital part of head j 

 somewhat lower than second dorsal and anal, which both are 

 emarginate and scaly. Origin of second dorsal opposite to 231^ 

 or 241^ lateral scale and to posterior half of anal. Pectorals as 

 long as or slightly longer than head, reaching vertical through
