Benthodesmus, Goode & Bean, Proc. U. S. Nat. Mus., iv, 1881, 380, (elougatus). 



Body naked, much compressed, attenuate, tapering gradually from vent 

 to base of caudal; caudal peduncle very slender, supporting a small but 

 well-developed caudal fin ; vent considerably nearer bead than to tail. 

 Lateral line simple, in a deep, -wide furrow, nearly straight, in front of 

 the vent gradually ascending to the scapular region. Head compressed, 

 its upper profile nearly horizontal ; snout gibbous near its end, as in Lepi- 

 dopus. Top of head very flat, concave between the eyes, with no occipital 

 crest ; interorbital ridges not elevated. Eyes large, slightly postmedian. 

 Operculum oblong, reaching a little beyond the* base of the pectoral fin. 

 Nostrils horizontal, in front of the eyes. Supramaxillary not extending 

 to vertical from front of eyes ; lower jaw with stout cutaneous appendage. 

 Three very long, simple, compressed teeth on each intermaxillary in front ; 

 outside of these a few minute teeth, and behind them a row of large acic- 

 ular teeth ; lower jaw with a single row of moderately large aciculav 

 teeth, more numerous than in the upper jaw, largest in the middle of the 

 jaw ; palatine teeth minute. Dorsal fin beginning above the operculum, 

 nearly uniform in height throughout its entire length, and continuous 

 almost to the caudal ; rays very numerous, 150 or more. Anal beginning 

 near the vent, preceded by a single scale-like appendage ; spines very 

 numerous (numbering with the rays about 100) all except about 30 being 

 spines, minute and almost hidden ; a short fin posteriorly ; caudal small, 

 normal, forked; pectoral inserted almost horizontally, with lower rays 

 longest, and its upper outline rounded ; ventral fins represented each by 

 a minute scale-like spine, inserted below the origin of the pectorals. 

 Pseudobranchite present; gills 4, a slit behind the fourth; gill rakers 

 short and spiny, in a single series on the first and second arches, almost 

 obsolete on the third and fourth. Deep-sea fishes ; two species known.
