spines are stout, and theii- length is more than one-half of that of 

 the head. The soft dorsal commences above the twent^'-fourth scale, 

 or above the hi-st soft ray of the anal; it is not scaly, higher than 

 long, as high as the spinous dorsal. Caudal cmarginate, short, its 

 length being a little more than one-sixth of the total. Anal fin as 

 high as, but rather longer than, the fin opposite. The least depth of 

 the tail is one-half of the length of the head. 

 Colour greenish, shining sUveiy.

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

 total length, the length of the head five times. The diameter of the 

 eye is contained thrice and two-thii'ds in the length of the head, and 

 once and a half or once and a third in the width of the interorbital 

 space ; eye with a broad adipose membrane. The praeorbital is scaly, 

 with a slight notch, and denticulated iufcriorly and posteriorly; 

 snout rather sharp, shorter than the eye ; the maxillary reaches be- 

 yond the prteorbital, and its extremity is visible ; upper lip thin ; a 

 large groove before the vomer. There are nineteen scales between 

 the snout and the first dorsal ; a long pointed scale in the axil. The 

 least depth of the tail is a little less than one-half of the length of 

 the head. Dorsal fins nearly equal in height : spines rather slender, 

 the fii'st being scarcely longer than the part of the head behind the 

 eye ; it is nearer to the extremity of the snout than to the base of 

 the caudal fin : the soft dorsal is higher than long, scaly below ; its 

 origin is above the middle of the anal fin. The anal is scaly, scarcely 

 higher than long, much longer, but only a little higher, than the soft 

 dorsal. Caudal emarginate, two-ninths of the total length. Pec- 

 toral nearly as long as the head. Coloration uniform ; a smaU black 

 spot superiorly at the base of the pectoral. {Bl.)

The height of the body is nearly equal to the length of the head, 

 and one-fifth of the total. The snout is short and obtuse ; the inter- 

 orbital space very shghtly convex, its width being two-fifths of the 

 length of the head. Lips thin ; the praeorbital has the anterior 

 margin nearly straight, neither toothed nor notched ; it does not 

 entirely cover the maxillaiy, the extremity of which is visible behind 

 the angle of the mouth. Eye with an adipose membrane. There are 

 twenty-two scales between the spinous dorsal fin and the snout. The
