fering in the following respects : Depth 3 in trunk (in gracilis 3|) ; eye 6 

 in head (in gracilis 5|) ; vomerine patch of teeth with the two arms 

 incurved (U-shaped in gracilis)', dorsal fin beginning behind the pectoral 

 (over root of pectoral in gracilis)] an additional series of large scales 

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

 trunk 2 in tail (2 in gracilis) ; ventrals shorter, not reaching past tips of 

 pectorals. Five specimens, the largest 9 inches long, from Albatross Sta- 

 tion 3010, at a depth of 1,005 fathoms, in the Gulf of California. (Gil- 

 bert.) (Ttpo, before; juska 5, black.)

Brotulids having the body elongate, compressed, covered with small 

 scales, and the head also scaled; lateral line incomplete, obsolete poste- 

 riorly. Eye moderate; snout moderate, rounded, slightly produced, the 

 lower jaw slightly included; no barbel. Teeth villiform, in narrow bands 

 in jaws and palatines ; vomerine teeth in a V-shaped patch ; 2 weak spines 

 at angle of preoperculum, and a stronger one at angle of operculum. 

 Gill openings wide, the membranes deeply cleft and not attached to 

 the isthmus; vertical fins united; ventrals reduced each to a bifid ray. 

 Branohiostegals 8. Pseudobrauchia3 present, but small. Air bladder 

 present. (rso<s, new; Byfhites.)

MARGINATUS, 2885. 



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 1 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 through 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- 

 ine patch subcircular, with angles extended posteriorly. Gill rakers 

 moderately long and slender, somewhat numerous, the longest about 

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

 branchiae 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 tube, almost upon tip of snout ; posterior nostril slightly 

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