6. Bathylagus pacificus sp. nov. 



This species differs from B. antarticus and B. atlanticus in the narrow 

 channeled iuterorbital space and the slenderer body. 



Anterior profile not decurved, the premaxillaries anteriorly on level 

 of middle of eye. 



Depth 1| in head and abont Gf in the length ; head 4. Eye 2J- in 

 head; snout short, less than half eye; iuterorbital space narrow, deeply 

 grooved, one-third diameter of orbit. 



Lower jaw with a series of small teeth, the very weak premaxillaries 

 toothless ; a strong series of teeth on vomer and palatines. 



Front of dorsal midway between adipose dorsal and front of snout. 

 Ventrals inserted under posterior end of dorsal. Anal inserted far 

 back, the vent immediately in front, the length of tail equaling that of 

 head. 



D. 8 or 9; A. 16 ; P. 9. Lat. 1. 40. 



Scales lost ; about forty in lateral line, judging from impressions on 

 the skin. 



Color: Head, lining of mouth and gill cavity, and peritoneum, jet 

 black. Fins blackish. In its present condition the general color of the 

 sides is black; margins of scale-pouches black. The fish was probably 

 wholly black in life. 



Two specimens, taken off the coast of Washington, at stations 3071 

 and 3074, in G85 and 877 fathoms. 



7. Synodus lacertinus sp. nov. 



With short snout, small scales, short pectorals and anal, and low 

 dorsal. 



Head, 3| in length ; depth, Sg. D. 11 ; A. 8. Lat. 1. 08. 



Snout, 4J in head, 2f in maxillary, its length slightly less than its 

 width at base. Eye over middle of preraaxillary, which is If in head ; 

 eye, 6. Iuterorbital width half snout. Occiput with well-developed 

 rugosities. 



Scales on cheeks crowded, in six rows. Four series between adipose 

 fin and lateral line. 



Front of dorsal nearer tip of snout than adipose fin by a distance 

 equaling diameter of pupil. The fin is low, the tips of anterior rays 

 barely reaching base of posterior ray in reflexed fin. Base of dorsal 

 1^ in head. Upper outline of dorsal convex. Anal very small, its 

 base one-third length of head. Pectorals very short, bluntly rounded, 

 the longest ray 2^ in head, not reaching beyond vertical trom base of 

 ventrals. Ventrals reaching half way to front anal, l^- in head. 



Color: Black, with five broad dark bars reaching to lateral line or 

 below. The middle of each interspace with a fainter bar confined to 

 back. Mandible below with alternating brown and silvery cross-bars. 

 A black spot at lower angle of cheeks, with a small silvery blotch be-
