Head 2f ; depth 2i. D. XI, 19 ; A. Ill, 9 ; scales 20-115 to 125-45 to 50, 

 70 pores. Body comparatively short and deep, strongly cocSpressed, the 

 back elevated, the anterior profile concave, forming a reentrant angle 

 before the eye, thence nearly straight to the nape. Head compressed, 

 the snout short, moderately pointed, 3| in head. Eye small, 51 in head. 

 Interorbital space narrow, anteriorly with a broad groove, which receives 

 the spines of the premaxillary bones, its width 8 in head. Posterior part 

 of head narrow, strongly convex transversely. Month small, obli(iue, 

 the jaws subequal, the broad maxillary extending to below the middle of 

 the eye, its length 2^ in head. Supplemental maxillary well developed. 

 Teeth in narrow bands, formed as in EpinepheJus, but small. Canines 

 scarcely differentiated, none in lower jaw, 1 on each side in upper jaw 

 slightly larger than the other teeth. Preopercle with very weak and 

 irregular serrations, the angle not salient, its teeth little, if any, 

 enlarged. A very slight emargination above the angle. Opercle with a 

 single spine, above which is a flat lobe. Opercular flap unusually large, 

 extending beyond the spine for a distance nearly equal to the diameter 

 of the eye. Gill rakers rather slender, nearly as long as gill fringes, 

 about 14 on lower part of anterior arch. Nostrils round, very close 

 together, the posterior the larger. Scales small, all cycloid, somewhat

 spots most numerous and distinct on the tail and on the lower part of 

 the head; several spots behind the eye, confluent into a pale stripe from 

 eye toward spinous dorsal ; fins all blackish, the pale spots smaller and
