Mouth narrow, muzzle protruding, giving head a pointed appear- 

 ance; outline of snout abruptly descending before eyes, profile of snout 

 slightly convex to almost vertical; anterior nostril with a short tube 

 which bears a lobate tentacle, posterior nostril with a raised rim; no 

 orbital tentacle; mouth small, maxillary ending at or before midpoint 

 of eye, chin with a median pit just behind m.andibular symphysis ; head 

 bones smooth, except for a feeble development of spination along the 

 path of the mucous canals of the frontals and the superficial bones 

 enclosing the supratemporal canal of the lateral line system; teeth in 

 both jaws conical, slightly recurved, arranged in bands, outermost 

 teeth of upper jaw somewhat enlarged; vomer with a V-shaped patch 

 of teeth; a small patch of teeth at head of palatine; soft rays of dorsal 

 and anal sim.ple, except for the ultimate ray, which is branched to the 

 base; principal caudal rays branched; pectoral formula typically ii,7,vii 

 or i,8,vii, first unbranched ray longest, lower 7 pectoral rays thickened; 

 pelvic rays two, inner ray the longer; pelvic rays bound together by a 

 membrane for about % the lengtli of the outer ray and somewhat more 

 than Ys the length of the inner ray; first dorsal spines not graduated, 

 third spine the shortest; outline of second dorsal even, first spine almost 

 as high as longest (third or fourth) , spines subsequent to the fourth or 

 fifth gradually decreasing in height; third dorsal soft ray longest; anal 

 spine about % as long as first anal ray; scales ctenoid, scalation much 

 reduced; no scales on head, nape, belly or pectoral base; upper sides 

 with at mxost one row of scales above lateral line back to level of miiddle 

 of second dorsal base, scalation becoming more complete back of this 

 point; upper sides seldom completely scaled at any point before end 

 of third dorsal; lower sides never completely scaled, lov/er surface of 

 caudal peduncle naked.
