Depth 5% to siibcaudal origin ; head 4%, broadly depressed, width 

 ll^ its length. Snout 21/2 in head, length 1% width, convexly 

 rounded; eye 5^2 in head, 2 in snout; mouth width 2 in head, length 

 half its width, short labial fold at hind edge of each lip; teeth 22 

 above, 36 below, rather large, tricuspid, median cusp slenderly tri- 

 angular and greatly longest; nostrils large, flap extends well over 

 lip or 1/} of interorbital ; cirrus from front nasal valve reaches mouth, 

 hind nasal valve without cirrus; nasoral groove rudimentary and 

 front nasal valves not confluent across internarial space. Gill open- 

 ings small, equidistant, last above pectoral base. Spiracle small, 

 close behind eye. 



Scales rather large, rough, tricuspid, median cusp greatly longest 

 and usually with keel. 



First dorsal inserted behind midlength, behind ventral base, front 

 edge 1% in head ; second dorsal inserted at middle in anal length, front 

 edge 2I/3 in head, fin slightly smaller than first dorsal; anal larger 

 than dorsals, length 1% in head; caudal 3I/2 in rest of body, front

 of large black rounded spots on the upper half of the body and over 

 all the fins.
