The head short, compressed, the front thick, prominent; the mouth small; the maxillae projecting, are 
divided in the middle and, as in this genus, form the teeth, two above and two below. The eyes are close to 
the vertex, in a deep rough socket, large, oval. The nostrils double, roundish, in the middle between the eye 
and the rostrum. The solitary branchial aperture close to the pectoral fin, small, and a little curve. 
The trunk: the back from the vertex, almost straight to near the dorsal fin, when it declines gently; it, as 
well as the sides, feels rough to the touch, but the belly is set with visible spiculi. There is no lateral line. The 
anus remote, or very distant from the head. 
The fins: the dorsal and anal are opposite to each other, near the tail; the pectoral fins are on a line with 
the mouth, fan-form when extended; the caudal undivided,oblong-square. The ventral fin (as in this genus) 
wanting. 
The colour: the back and sides are of a dark colour, spotted with pale bluish dots on the shoulder, but with 
oval spots behind the pectoral fin; the belly a bright yellow. 
The length, from the rostrum to the end of the tail, four inches, three lines.
