upper lip thin ; no groove before the vomer. There arc twenty-one or 

 twenty-two scales between the snout and the first dorsal fin ; a short 

 pointed scale in the axil. The least depth of the tail is one-half, or 

 rather more than one-half, of the length of the head. The dorsal fins 

 are ncarlj' efjiial in height ; the spines are strong : the th-st is the 

 strongest, and longer than the part of the head behind the orbit ; it 

 is much nearer to the base of the caudal fin than to the extremity 

 of the snout. The soft dorsal fin is nearly entirely scaly, much 

 higher than long: the anal fin is scaly, and nearly wholly situ- 

 ated before the soft dorsal ; it is scarcely higher, but much longer, 

 than the soft dorsal : caudal fin emarginate, one-fifth of the total 

 length. Pectoral much longer than the part of the head behind the 

 orbit. Coloration unifonn, fins blackish towards the margin ; anal 

 generally with a whitish margin. (Bl.)

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

 times and a half in the total length, the length of the head four times 

 and two-thirds. The greatest depth of the head is two-thii'ds of its 

 length. Eyes without adipose membrane. Snout much shorter than 

 the eye ; preeoi-bital slightly notched anteriorly ; maxillary entirely 

 hidden ; upper lij) thin. Pectorals shorter than the head ; the second
