 rays, inserted opposite to the root of the ventrals. Anal fin with ten 

 or mor(^ rays. Uarhels none. The maxillary reaches to or behind 

 the front margin of the orbit. Suborbitals not dilated. Gill-rakers

 Mouth very wide, the uuixillary extending to below the middle of 

 the eye. Each intermaxillary with a strong prominence on each 

 side near its upper end, fitting into a notch of the lower jaw. The 

 height of the body is contained four times and two-thirds in the 

 total length (without caudal), the length of the head thrice and two- 

 fifths. The origin of the dorsal fin is midway between the end of 

 the snout and the root of the caudal. None of the anal rays pro- 

 longed. Coloration miiform. (ScJiJeij.)

Mouth ratlier Avide, the maxillary scarcely extending beyond the 

 vertical from the ft'ont margin of the eye. The front part of the 

 anal fin is elongate, but scarcely reaches the root of the caudal if 

 laid backwards. Pectoral fin not extending to *fhe ventral. The 

 height of the body is a little more than the length of the head, which 

 is one-fourth of the total (without caudal.) Suborbital ring very 

 narrow. Coloration uniform. (/SeJiJq/.')

 Mouth rather wide, the maxillary extending somewhat bcj'ond the 

 vertical from the front margin of the eye. The four or five ante- 

 rior branched anal rays arc elongate (in adulf specimens), extending 

 to, or nearly to, the root of the caudal, if laid backwards. Pectoral 

 fin not extending to the ventral. The height of the body is nearly 

 equal to tb.e length of the head, v>'hicb is scarcely more than one- 

 fourth of tlic total (williout cand;il). Suboi'bital ring very narrow, 

 the middle bones being only one-third O'^ broad as llic niMit. (Snout
