ICHTHYOLOGICAL COLLECTIONS OF THE ALBATROSS. 445 
even; the snout very slightly protruding beyond premaxillaries. 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, 14 in total 
interorbital width, equaling length of snout. Gill-opening a small pore, scarcely 
larger than nostril, well separated from upper margin of pectoral. Disk of moderate 
size, round, its diameter equaling half length of head. Vent 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 
12 in distance of latter from base of caudal. Dorsal withabout45rays. 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 34 mm. in diameter. 
RHINOLIPARIS gen. nov. (LIPARIDIDZ.) 
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 &. barbulifer 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, 
24 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 pseudobranchiz. 
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 not 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 
85mm. 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.
