The height of the body is contained five times in the total length 

 (without caudal), the length of the head thrice and a half or thrice 

 and three-fifths ; the least dejith of the tail is more than one-half 

 of the height of the body ; depth of the head three-fifths of its 

 length ; eye of moderate size, two-ninths of the length of the head ; 

 the distance between the jjosterior margin of the orbit and the 

 prajopercular edge is less than the diameter of the eye ; posterior 

 margin of the prseopercidum descending obliquely backwards. Snout 

 obtusely conical, with the jaws equal in front. Cleft of the mouth 

 nearly horizontal. The maxillary reaches to the angle of the prge- 

 operculum, and is scarcely dilated behind. The origin of the dorsal 

 fin is midway between the extremity of the snout and the adipose 

 fin, and above the root of the ventral ; its last ray is above the 

 middle of the anal. Pectoral fin shorter than the ventral, and not 

 extending beyond its root. Scales perfectly smooth, those of the 

 lateral line rather larger than the others.

 D. 26. A. 18. V. 8. L. lat. 36. 



The height of the body is contained five times and a half in the 

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

 two-thirds ; the least depth of the tail is one-half of the height of 

 the body ; depth of the head tkree-fifths of its length ; eye of mode- 

 rate size, two-ninths of the length of the head ; the distance between 

 the posterior margin of the orbit and the praBopercnlar edge is less 

 than the diameter of the eye ; posterior margin of the praeoperculum 

 descending obliquely backwards. Snout obtusely conical, with the 

 jaws eqiial in front. Cleft of the mouth rather oblique. The 

 maxillary reaches to the prseoperculum, and is not dilated behind. 

 The origin of the dorsal fin is midway between the extremity of the 

 snout and the adipose fin, and above the base of the outer ventral 

 rays ; its last ray is behind the vertical from the middle of the anal. 

 A series of from six to nine small spines bent backwards, above and 

 below, before the root of the caudal. Pectoral fins shorter than the 

 ventral, and not extending beyond its root.
