VOL. XXV. 



mouth small, its cleft nearly vertical; premaxillarj- with a very long- 

 process, so that it is extremely protractile, perhaps less so than in 

 Cajmj^; lower jaw projecting; upper jaw somewhat protractile; max- 

 illary broad, scaly; small, very slender teeth on jaws in one row, none 

 on palate; chin rough; preopercle with rough striae, becoming antrorse 

 spines below; cheeks deep, covered with rough scales; opercle short, 

 scaly. Branchiostegals 6; gill-membranes separate, free from isthmus. 

 Lateral line concurrent with the back. Fin spines stiff and strong. 

 Dorsals united, the third spine stout and elevated, the sixth or last 

 spine shortest, lower than the soft rays; the tin is thus distinctly 

 notched. Soft dorsal and anal similar, long and low, none of the rays 

 produced; anal spines 3, joined to the tin, the first longest. Base of 

 dorsal and anal with a sheath of small, rough scales extending on the 

 fin spines and slightly on the rays, not on the membranes; caudal 

 peduncle short and deep, deeper than long; caudal short, sijuarely 

 truncate; ventrals strong, of moderate length, at lowest point of ven- 

 tral outline, well behind pectorals and directly below spinous dorsal, 

 which is at its highest point of dorsal outline; ventral spine large, 

 roughened anteriorly; pectorals moderate, not falcate. Species few, 

 in waters of moderate depth.

Head 8; depth (greater with age and always more than the length of 

 the body) exceeds the length of the body by half an eye diameter. 

 D. VIli-36; A. 111-33; P. I, 13; V. I, 5; scales 15-59-41. Body 

 covered with rough ctenoid scales, very deep and elevated, the ))ack 

 forming a sharp angle at an equal distance from the tip of the snout 

 and the caudal peduncle in fi-ont, the apex forming the origin of the 

 spinous dorsal; below the profile of the body is hemispherical. Head 

 deep, the upper profile convex from the tip of the snout and tiien 

 becoming concave over the eye in front; snout two-thirds the eye and 

 equal to the interorbital space; eye large in the upper part of the head 

 and 2i in its length; maxillary short, broad, the width equal to one- 

 third the eye, the length 4 in the head, not extending to the lower 

 margin and not reaching the anteilor margin of the eye; preorbital
