The body is somewhat compressed; its greatest height (40""") is cou- 

 tained G^ times in the total leugth. 



Scales small, deciduous,* as nearly as can be counted 25 rows in an 

 oblique line from the vent to the dorsal fin, 24 from the u})per angle of 

 operculum to the vertical through the origin of the anal. 



Leugth of head (55™'") contained 5| times in total length. Inter- 

 orbital area nearly flat, its width contained 4 times in length of head. 

 Postorbital part of head (26'""') somewhat longer than diameter of eye, 

 which is nearly round, its leugth (20""") contained 2f times in length 

 of head. Snout broad, obtuse, its length (li™">) contained 5 times in 

 that of the head. Il^ostrils close to the eye, the posterior nearly twice 

 as large as the anterior one. The maxilla extends to the vertical 

 through posterior margin of orbit, its length (30'""^) equal to that of 

 head without its postorbital portion. Length of mandible (34"^™) equals 

 3 times that of the snout. Intermaxillaries and mandible provided with 

 narrow bands of villiform teeth, those in the mandible much shorter. 



A minute barbel, about one-third as long as snout. Vomer and 

 j)alate toothless. 



Gill-rakers lanceolate, elongate, 26 on first arch, 7 above the angle, 

 the longest one-seventh as long as the head. Pseudobranchioe absent. 

 The first dorsal consists of 2 short si^ines and 8 branched rays, its dis- 

 tance from snout (62"^™) contained nearly 5 times in the total length. 

 The second or longest ray in the typical specimen twice the length of 

 snout. The second dorsal, which contains about 125 rays, is almost con- 

 tinuous with the first, its anterior rays the longest, about 4 times in 

 length of head. 



The anal is inserted under the fourteenth ray of second dorsal. Its 

 rays are all very short. In a distance equal to length of head, counting 

 back from insertion, there are 33 rays. 



The pectoral is inserted under the first branched ray of the first dorsal; 

 its length in the most nearly perfect specimens equals the length of the 

 head without the snout. 



The ventral origin very slightly behind origin of pectoral under the 

 third branched ray of the dorsal, reaching nearly to the vent when laid 

 back. Its length (35™"^) equaling three times that of snout. Eays 8. 

 Branchiostegals 7. 



Color yellowish gray, lighter below. 



Bathygadus longifilis, n. s. 



The types, No. 37338, are 2 specimens taken by the Albatross at 

 station 2392, north latitude 28° 47' 30", west longitude 87° 27' 00", depth 

 724 fathoms, 225 and 233 millimeters in length, the measurements taken 

 from the largest. 



The body is more compressed than in B. macrops. Its greatest height 

 (31""') contained 7^ times in total leugth. 



* Not one of our specimens has scales, so their character cannot be made out, nor 

 can the lateral line he described.
