 row enlarged; on each side of lower jaw posteriorly a pair of large, 

 curved canines which project in front of upper lip; least height of 

 caudal jDeduncle about 0.5 its length and 0.5 head; branchial aper-

 pore at each end of interorbital space. 



Fins: Dorsal VI-I,9; spinous dorsal low, the spines slightly 

 produced, the longest less than depth of body; second dorsal rather 

 low, its base less than length of head, the posterior rays reaching 

 caudal when depressed; caudal broad, rounded, rather short, less 

 than head ; anal similar to second dorsal, its ray 1,9 ; ventrals broad, 

 rounded, extending nearly or quite to vent; pectorals as long as 

 head less snout and reaching slightly beyond ventrals.
