 (lateral line) along middle of sides, and another along ventral outline;

2884. NEOBYTHITES GILLII, Goode &. Bean. 



Body compressed, its height contained 4| times in total length, and less 

 than length of head ; interorbital area convex, its width equal to diameter 

 of circular eye, 3f in length of head, and li in length of snout in young. 

 Head compressed, deeper than broad, with wide sinuses, its length con- 

 tained 4| times in that of the body; snout obtusely rounded, slightly 

 produced; mouth large, the maxillary extending considerably behind the 

 vertical througli posterior margin of eye, expanded posteriorly; mandible 

 still longer, its length about 2^ times in height of body ; interorbital 

 space convex. Teeth in villiform bands in jaws and on palatines; vomer-

 moderately long and slender, somewhat numerous, the longest about | 

 diameter of eye, 11 developed and 3 rudiments below the angle. Pseudo- 

 branchiie absent; gill opening wide, the membrane deeply cleft, free 

 from the isthmus behind. A single long, flat spine attached to posterior 

 portion of operculum, high up, extending back to its edge; a small hidden 

 spine at lower angle of preoperculum. Nostrils small, the anterior one 

 in a very short tul)e, almost upon tip of snout; posterior nostril slightly 

 larger, not tubular, immediately in front of middle of eye. Scales mod-
