attached to the isthmus. Gills 4. Gill-laminae well developed. Gill- 

 rakers slender, rather short, moderately numerous. Pseudobranchise 

 absent, Branchioste^als 8. 



The caudal hu is few rayed, pointed, not well differentiated from the 

 vertical fins. 



The dorsal and anal fins are well developed, the anterior rays the 

 longest; the outliue is continuous to the tip of the caudal. Pectorals 

 broad, of moderate length, normal in form, sessile. 



Each ventral a single ray, placed close to the humeral symi)hysis. 



The scales are small. Lateral line incomplete, being obsolete pos- 

 teriorly. 



Neobythites Gilli, n. 8. 



Tlie type, jSTo. 37340, is from Albatross station 2402, north latitude 

 28° 3G', west longitude 85° 33', depth 111 fathoms. 



Description : Body compressed, its height (17'"") contained 4f times 

 in total length and less than length of head. Interorbital area convex, 

 its width (5""^') equal to diameter of circular eye, 3| in length of head, 

 and li in length of snout. 



The length of the head (18°'"') is contained 4^ times in that of body. 

 Mouth large, the maxilla extending considerably behind the vertical 

 through posterior margin of eye, expanded posteriorly; the mandible 

 still longer, its length (11""") about 2^^ times in the height of the body. 

 Teeth in villiform bands in the jaws and on the palatines. Vomerine 

 patch broadly V-shaped, with a circular bunch at the angle. 



Gill-rakers moderately long and slender, somewhat numerous, the 

 longest about two- thirds diameter of eye; eleven developed and 3 rudi- 

 ments below the angle. Pseudobranchige absent. ' Gill -opening wide, 

 the membrane deeply cleft, free from the isthmus behind. A single long 

 flat spine attached to the posterior portion of the operculum, high up, 

 extending back along to its edge. 



Nostrils small, the anterior one in a very short tube, almost upon the 

 tip of the snout ; posterior nostril slightly larger, not tubular, immedi- 

 ately in front of middle of eye. 



No apparent cirri. 



Scales moderate, in 88 vertical rows, 7 rows between dorsal origin and 

 lateral line, which becomes obsolete in its posterior half; 10 to 17 from 

 vent forward to lateral line. 



Dorsal origin l)ehin<l ventral and pectoral. Its distance from snout 

 (21""") contained 4 times in total length. Its rays moderately long. 



Anal origin under the eighteenth dorsal ray. Its distance from snout 

 (34'""^) contained 2;^ times in body length. Eays rather slenderer than 

 those in the dorsal. 



The caudal consists of 6 or 7 rays ; its length (9™°*) contained 9 times 

 in total length. 



Pectoral origin well forward ; its base somewhat concealed by the
