bia; known from 3 specimens, 520 to 550 mm. long. (CTilbert.) (filum, 

 thread; fero, I bear.) 



Chalinura filifera, Gilbert, Kept. U.S. Fisli Comm. 1893 (1896), 4.58, off Queen Charlotte

2953. CHALINURA SIMULA, Goode & Bean. 



Head 5; depth 6; orbit 6 in head; snout 3; interorbital width greater 

 than eye; postorbital part of head 3 times as long as eye; opercle 2 in 

 upper jaw. D. II, 9-113; A. 118; P.20; V.9; Br.6; scales 8-150-17 to 19. 

 Body shaped much as in Coryphamoides, but rather stout; back more gib- 

 bous in profile, the dorsal outline rising quite rapidly from the interor- 

 bital region to origin of first dorsal, thence descending almost in a straight 

 line to end of tail. Preopercle emarginate on its posterior limb. Snout 

 broad, obtuse, scarcely projecting beyond the mouth, its width nearly 

 as great at tip as its own length; median ridge very prominent, gibbous 

 in outline when viewed laterally ; lateral ridges starting almost at right 

 angles with the median, and continued upon sides of head; no supraor- 

 bital ridges. Nostrils in front of middle of eye, and nearer its anterior 

 margin than to tip of snout; barbel longer than eye; teeth in upper jaw 

 in a broad villiform band, the outer series very much enlarged ; lower jaw 

 with teeth in a single series. Scales rather small, but with indications, 

 particularly on the head, of radiating strise. Origin of first dorsal from 

 snout 4^ in its base, or from anterior margin of orbit 1 in head ; first dor- 

 sal spine very aliort, second rather stout, 1| in head, and with a simple 

 serration anteriorly, the serrse closely appressed to the spine; second dor- 

 sal separated from the first by a distance equal to length of upper jaw; 

 anal high, its average rays about 3 times as long as those of dorsal, in- 

 serted slightly behind perpendicular from last ray of first dorsal; pecto- 

 ral inserted over base of ventral; origin of ventral from snout less than 

 its longest ray, which is i)roduced in a filament extending to base of eight- 

 eenth anal ray. (Goode & Beau.) West Indies and Gulf Stream, in deep 

 water, (shnulus, pug-nosed.)

 jaws somewhat enlarged. Scales spinous, second or elongate dorsal ray 

 finely serrated in front. Lower jaw with a barbel at tip. Deep Sea.
