The body wedge-form, a little compressed, very small near the caudal fin; no scales. 
The head nearly as broad as the body, scabrous, and armed with many spines; the front declivous, grooved ; 
a long curved spine on each side of the rostrum, two or three small prickles in front. Mouth large. Jaws 
extractile, nearly equal, the superior emarginate, and two small cirri pendent from the lower. Teeth small, 
acerose. Tongue short, smooth, obtuse, loose. Palate wide, tuberculate. The eyes close to the crown in a deep 
prickly orbit. Nostrils double, unequal in size, close on the point of the rostrum. 
Branchial opercula rugged, and armed with small spines pointing backward; the membrane half exposed, 
the aperture large. 
The trunk. The back and throat rather flat, the tail a little compressed. The branchiae pectinate on the 
inside. Lateral line supreme, gently arched, and terminates at the upper edge of the tail. The anus remote. 
The fins. The dorsal single, the eleven spinal rays nearly equal in height, the posterior part of the fin 
higher and rounded; the pectoral broad, half as long as the trunk, acuminate at top; the ventral broad, half the 
length of the pectoral; the anal equal, narrower than the opposite dorsal; the caudal truncate, and, as in all the 
others, the point of the rays extend beyond the membrane. The digiti liberi exactly under the pectoral fins. 
The colour a dusky purple; the belly pink. The points of the dorsal spines and the margin of the membrane 
black, the posterior portion darkish purple. Pectoral and ventral fins reddish with a purple tint. The tail dark- 
purple, with two light coloured bands.
