twice as long as the outer and reaching to the base of the pectoral 

 fin; a tuft of small curved spines on the under side of the head at 

 each outer posterior angle of the mandibula; teeth in villifonn bands 

 on jaws, vomer, and palatines; tip of tongue convex. 



Spinous dorsal (in male ?) relatively high, the fin when depressed 

 reaching to the second ray of the soft dorsal; longest dorsal spine 

 1.6 in head; soft dorsal highest posteriorly, without filamentous 

 rays, its longest ray 1.3 in head; soft dorsal and anal nearly opposite, 

 both very long, the anal base being nearly twice head; pectoral, 

 1.4 in head; 3 detached pectoral rays, the longest extending fully to 

 tip of pectorals, 1.3 in head; ventrals, 1.8; caudal rounded. 



Color in spirits yellowish brown, the back crossed with 4 obscure 

 cross-bars of dusky, and with many fine punctulations in small, 

 vaguely outlined clusters; belly pale; spinous dorsal with obscure 

 spots of dusky, forming rows across both rays and membranes; soft

dorsal mottled, the light color in roundish spots between the rays; 

 caudal and pectorals with the rays specked and \vith the membranes 

 clouded with dusky; anal pale except for a narrow outer edging of 

 blackish. 



This species differs from Hopliclithys gilherti and from Hoplichthys 

 citrinus Gilbert in having fewer (only 16) rays in the anal fin, in its 

 much longer pectoral appendages, and in the presence of a tuft of 

 spines on the under side of the head at the outer posterior edge of 

 each mandible. The representation of two well-developed spines at 

 the angle of each lateral scute in the figure of Cuvier and Valenciennes 

 is doubtless fallacious, the figure correctly shoA\dng, however, practi- 

 cally all of the remaining essential features of Cuvier' s description 

 and of our own specimen, including the tuft of spines under each jaw. 

 The fins of Cuvier' s specimen were damaged and no certain value can 

 be attached to the rendering of their form. The number of anal rays.
