 in head, as seen from above rather widely triangular; eye 5, 2% in 

 snout, 2% in interorbital, depth 1% its length; dentary width 

 3% in head, with deep labial grooves around mouth angle, 

 upper short and lower greatly longer or equals separation of folds 

 across symphyseal space; teeth in 24 rows in jaws, compressed, tri- 

 cuspid, cusps as larger median and small basal one each side, edges 

 entire; nostrils about last fourth in preoral space, nasoral groove

 with small external fleshy point or papilla; interorbital 2%, de- 

 pressed, scarcely convex. 



Gill openings small, fourth and fifth so close as almost to appear 

 as one aperture and with third above level of pectoral base. Spiracle

 eye opposite hind eye edge each side of pharynx, covered with 

 shagreen. 



Scales moderately fine, triangular, each ends in point behind and

First dorsal origin well behind ventral base, about midway be- 

 tween ventral and anal origins, front edge li/^ in head ; second dorsal 

 origin midway in anal length, front edge 1% in head length; anal 

 origin little nearer that of subcaudal than hind basal edge of ventral ; 

 subcaudal length greater than head to last gill opening or II/5 in 

 caudal length, low or its height 11% in its length; pectoral width 

 1% its length which 1% in head; ventral length li/io-
