 first dorsal \\ in interspace between dorsals, Avhich is 2| in head; distance 

 from front of anal to snout equaling \ total length; ventrals with the 

 outer ray pro<luced, about reaching front of anal ; pectorals reaching l>eyond 

 anal i length of head; ventrals with 7 rays; pectorals with 15 to 17 rays.

 smooth; dorsal much lower than anal; teeth in both jaws in villiform 

 bands; snout obtuse, the mouth sul)inferior; suborbital ridge little 

 developed. This genus is distinguished from Culorhynchus by the indis-

 7-175 or more — 33. Barbel 2^ to 2 in eye. Body elongate, rapidly con- 

 tracted l)ehind the abdomen; the tail long and whip-like. Scales mode- 

 rate, strongly armed, each with 8 to 10 spinelets, irregularly placed, less 

 numerous in the young, which feel bristly to the touch, separated by wide

 upon snout, cheeks, and chin have very feeble spines. Interorbital area 

 nearly flat, its length equaling diameter of eye or al)Out 3 in head ; post- 

 orbital part of head as bmg as eye; suout short, obtuse, scarcely over- 

 hanging the inoutli ; nostrils somewhat above level of middle of eye, the 

 anterior one nearly upon the dorsal outline. U]>per jaw with 2 series of 

 teeth in villiform bauds, the outer series .slightly enlarged ; teeth of lower
