ICHTHYOLOGICAL COLLECTIONS OF THE ALBATROSS. 445 



even; the snout very slightly protruding beyond preraaxillaries. Teeth slender, 

 acicular, without cusps, the inner teeth longest. Bands of teeth very narrow, with 

 but five or six oblique series in each half of each jaw. The teeth are directed back- 

 ward, but are scarcely depressible. Nostrils without tube. Eye large, 1^ in total 

 interorliital width, equaling length of snout. Gill-openiug a small pore, scarcely 

 larger than nostril, well separated from upper uiargin of pectoral. Disk of moderate 

 size, round, its diameter equaling lialf length of head. A'ent close behind disk, sepa- 

 rated from it by one-sixth its distance from front of anal fin. 



Pectoral small, its upper edge on a level with lower margin of eye, the two fins 

 converging under the throat, the anterior rays progressively shortened, all included 

 within the membrane. Dorsal without any detached anterior portion, beginning 

 well behind the head, at a distance from gill-opening equaling one-half length of 

 head. Like the anal, it is continuous with the very narrow caudal fin, there being no 

 notch or evident separation between them. Distance from tip of snout to front of anal 

 If in distance of latter from base of caudal. Dorsal with about 45 rays. Caudal with 

 a very narrow base, containing apparently 14 rays, its length equaling that of snout 

 and eye. Color light brownish, everywhere dusted with minute black specks, which 

 are largest on back and tail. Lining of mouth and gill-cavity and peritoneum white. 



A single specimen, 67 mm. long, from station 3331, north of Unalaska Island; 

 depth 350 fathoms. 



Eggs large, visible through the abdominal wall, about 3^ mm. in diameter. 



RHINOLIPARIS gen. nov. (LIPARIDID^.) 



Allied to Paraliparis, from which it differs in the greatly produced snout, which 

 much overlaps the mouth and bears at its tip a pair of barbels. No sucking disk. 

 Vent anterior, between the pectoral fins. Pectorals deeply notched, continuous. 

 Gill-openings narrow, mostly above the pectorals. Teeth acute, in a broad band in 

 each jaw, arranged in oblique series within the band. (Type li. harbulifer sp. nov.) 



100. Rhinoliparis barbulifer sp. nov. 



Slender, compressed, the greatest depth just in front of dorsal, the nuchal region 

 not greatly swollen. Body tapering into an extremely slender, almost filamentous 

 tail. Mouth small, horizontal, inferior, overpassed by the broadly rounded, very 

 soft snout for a distance equaling diameter of pupil. At the tip of the snout, sepa- 

 rated by a space half as wide as pupil, are two barbels directed forward, each as 

 long as the interspace. Maxillary reaching vertical from posterior border of orbit, 

 2i in head. Eye large, slightly less than one third head. Bony portion of inter- 

 orbital width narrow, three-fourths diameter of pupil. Gill-slit narrow, beginning 

 opposite upper pectoral rays, two-thirds diameter of orbit. No pseudobranchise. 

 Opercle prolonged posteriorly into a narrow pointed flap. Round mucous pores 

 along under side of snout and suborbital and on under side of mandible. 



Pectorals of two lobes, the lower narrow, containing but 4 or 5 rays, the upper 

 with about 15, one or two widely spaced rays connecting the two, none of the rays 

 free. The fin is inserted high, the upper end of base on a level with upper edge of 

 pupil. Below, the fins are uot approximated as closely as usual, the lowermost rays 

 of the two fins separated by an interspace as wide as pupil, inserted vertically below 

 middle of cheeks. The dorsal originates slightly in front of gill-slit. 



Vent anterior in position, its distance from front of pectorals two-fifths its distance 

 from front of anal fin. Head 5| in length ; depth 7. Length of specimen described 

 85 mm. In spirits, light gray, dusky along bases of dorsal and anal fins, and on the 

 nape. The black lining of abdominal cavity, gill-cavity, and mouth can be seen 

 through the transparent integuments. Eye also black. Barbels transparent, hence 

 very inconspicuous. 



Several specimens taken north of Unalaska Island, stations 3227, 3325, 3326, 3329, 

 3330, 3331, and 3332; depths 225 to 576 fathoms.
