The height of the body is two-elevenths of the length (without 

 caudal) ; the length of the head one-fourth. The depth of the 

 head is less than the distance between the extremity of the snout 

 and the hind margin of the praeoperculuin, and is contained once 

 and three-fourths in its length. Snout obtuse and short, three- 

 fourths the length of the diameter of the eye, which is nearly 

 one-fourth of the length of the head, and somewhat less than the 

 width of the interorbital space, which is quite flat. The pectoral 

 fin extends to the root of the caudal. Ventral fin midway between 

 the end of the snout and of the dorsal fin, terminating at a great 

 distance from the vent. The dorsal fin commences a little in 

 advance of the anal, its anterior rays not being half as long as 

 the head. There are twenty scales between the occiput and the 

 origin of the dorsal, and six longitudinal series of scales between 

 the origin of the dorsal and the lateral line. Pectoral uniform 

 blackish, with the lower border whitish. Ventrals white.
