their scientific value is much lessened ; and that, in the descriptions, 

 very little notice has been taken of those characters by which alone 

 the different species can be distinguished.

The height of the body equals the length of the head, and is one- 

 fifth of the total ; the head is three-fourths as high as long ; the 

 diameter of the eye is contained thrice and a third in the length of 

 the head, and is two-thirds of the width of the interorbital space. 

 Eyelids not developed. The upper profile of the head and nape is 

 convex. Prjeorbital scaly, slightly emarginate and indistinctly den- 

 ticulated ; snout shorter than the eye ; the maxillary extends beyond 

 the praeorbital, and its extremity is uncovered ; upper lip thin ; no 

 groove before the vomer. There are eighteen or nineteen scales 

 between the snout and the dorsal fin ; the scale in the axil is short. 

 The least depth of the tail is one-half of the length of the head. 

 The spinous dorsal fin is higher than the soft ; the spines are strong, 

 the fii-st being the longest and strongest, longer than the part of the 

 head behind the orbit ; it is nearer to the base of the caudal than to 

 the end of the snout. The soft dorsal fin is entirely scaly, twice as 

 high as long : the anal fin is entirely scaly, a little nigher and much 

 longer than the soft dorsal ; its anterior third is before the origin of 

 the soft dorsal : caudal fin emarginate, its length being contained 

 four times and three-fifths in the total. Pectoral shorter than the 

 head. Coloration uniform.

The height of the body is contained four times and a third to four 

 times and three-fourths in the total length, the length of the head 

 five times to five times and two-fifths ; the diameter of the eye is 

 contained four times in the length of the head, and once and three- 

 quarters in the interorbital space. Adipose eyelid not developed ; 

 prteorbital slightly emarginate anteriorly, truncated and denticulated 

 posteriorly. The snout is nearly as long as the eye, somewhat shorter 

 in immature specimens ; the extremity only of the maxillary is visible ;
