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

 (without caudal the length of the head thrice and one-fourth ; the 

 least depth of the tail is two-fifths of the height of the body ; the 

 depth of the head is contained once and two-fifths in its length. Eye 

 very large, its diameter being two-fifths of the length of the head ; 

 the distance between the posterior margin of the orbit and the prae- 

 opercular edge is one-fourth of the diameter of the eye. Snout short, 

 obtusely conical, its upper and lower profiles being nearly equally 

 curved. Cleft of the mouth oblique, with the lower jaw prominent ; 

 the maxillary reaches to the angle of the praeoperculum, and termi- 

 nates in a triangular dilatation. The origin of the dorsal fin is nearly 

 midway between the extremity of the snout and the root of the caudal, 

 immediately behind the base of the ventral ; its last ray is in the ver- 

 tical from the third or fourth anal ray. The pectoral fin extends 

 nearly as far backwards as the ventral. Scales smooth, those of the 

 lateral line not larger than the others ; there are nine scales between 

 the adipose and caudal fins. Most of the specimens have an ellip- 

 tical, bright, pearl-coloured patch on the back of the tail.

The height of the body is contained four 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 two-fifths of the height of 

 the body ; the depth of the head is contained once and two-fifths in 

 its length. Eye large, its diameter being contained twice and two- 

 thirds in the length of the head ; the distance between the posterior 

 margin of the orbit and the praeopercular edge is one -third of the 

 diameter of the eye. Snout short, obtusely conical, its upper and 

 lower profiles being nearly equally curved. Cleft of the mouth 

 oblique, with the lower jaw prominent; the maxillary reaches to the 

 angle of the praeoperculum, and terminates in a triangular dilatation. 

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

 snout and the root of the caudal, above the middle of the distance 

 between the bases of the ventral and anal fins ; its last ray is in the 

 vertical from the sixth of the anal fin. Pectoral fin very small, 

 scarcely extending to the root of the ventral. Scales smooth, those 

 of the lateral line elevated and larger than the others. There are five
