little backwards, and then pursues a nearly straight course to 
the extremity of the second dorsal, where it suddenly curves 
downwards, and then passes to the middle of the tail; a few 
small tubercles are upon each side of it. 
The first dorsal fin is sub-triangular. 
Second dorsal longer than high. 
Pectorals large and rounded; extremities of all the rays 
free, except the few first. 
First ray of ventrals strongly spinous. ` 
Anal commences just back of origin of second dorsal, and 
terminates on a line with that fin. 
The caudal fin is even at extremity.
