the anal, its base 0.40 length of head. Caudal forked. Pectoral 

 inserted below the middle of the depth, its upper ray below level 

 of pupil: length of pectoral, 0.45 of head, scarcely reaching verti- 

 cal from base of ventrals. Base of ventrals slightly nearer base of 

 caudal than tip of snout. 



Body completely invested with cycloid scales, which do not extend 

 on the bases of the fins. 



Dark brown throughout on body and fins, the head nearly black.

A single scale in one specimen still attached to the middle of the 

 dorsal region is nearly twice as deep as long, cycloid in structure, 

 and with entire margin. There were apparently 38 scales in a series 

 along middle of sides. The ventrals are inserted somewhat in ad- 

 vance of the middle of the dorsal, but little behind a vertical from 

 origin of dorsal. 



BATHYLAGUS PACIFICTJS Gilbert. 

 Bathylagus horealis Gilbert, Rept. U. S. Fish Comm. for 1893, 1896, p. 402. 



Four specimens of this rare form were obtained in better condition 

 than any previously secured. From these it appears that the char- 

 acters alleged to distinguish it from B. horealis from Bering Sea are 

 unreliable. The depth of body in these specimens is contained from 

 5 J to 5 J times in total length without caudal. The distance from 

 front of anal to base of caudal exceeds the length of the head and is 

 contained 3J to 3-f times in total length without caudal. The front 

 of dorsal is midway between the insertion of adipose fin and the tip 

 of the snout, or slightly nearer the latter. Dorsal, 10 or 11; lateral 

 line, 40. The last two rays of the dorsal and anal are closely apposed 

 and might be considered a single ray split to base.
