This species agreeing in general with the former, in its generical characters, differs somewhat in the form of 
the body; the back is more convex and the tail near the end becomes almost quite round. The tongue, of the 
usual shape, resembles a piece of firm, clear jelly. 
The colour of the whole, except the belly, dark brown, the sides marked with three or four dusky longitudinal 
lines, and a few spots of a colour still darker. The rays of the dorsal and anal fins are also spotted; and on 
the first dorsal is a remarkable round, black mark; the caudal is streaked transversely, as in No. LI. but the 
fin differs in shape.
