ering the teeth. Teeth large, very powerful, the cutting edges of the 

 mandibulars more concave than those above, and the suture with a 

 pronounced groove but no ridge on either side. Bifid tentacles large, 

 very conspicuous, and placed about the last third of the space between 

 the upper lip and the front margin of the eye. Interorbital space 

 broad and slightly convex. 



Gill-opening equal to the internasal space or not quite as wide as 

 the base of the pectoral. 



Peritoneum silvery. 



Lips, eyehds, margin of gill-opening, bases of the fins and the caudal 

 peduncle naked, the other portions covered with rather large sharp 

 spines, those on the belly longest and more or less slightly clavate. 



Origin of the dorsal fin is much nearer the posterior margin of the eye 

 than the tip of the caudal fin, and the fifth ray is the highest. The 

 anal is similar to the dorsal, entirely posterior, and with the sixth ray 

 the longest. Caudal long, rather broad, and with the margin slightly 

 rounded. Pectoral broad, the upper rays the longest, and the fin 

 rather short. All the fins have rounded edges. 



Color in alcohol dark brown, the belly paler, and everywhere more 

 or less uniform. Dorsal, anal and pectoral uniform pale brown. 

 Caudal dark brown, with the margin all around broadly bordered with 

 blackish brown. Each prick or spine is pale or whitish. The lips and 

 bases of the fins are very dark brown.
