442 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 
and lower rays of the fin are fine and crowded, the middle third of the base being 
occupied by 4 or 5 more widely spaced rays. The fin has 25 rays, of which 9 belong 
to the lower lobe. The upper lobe extends beyond origin of anal fin. None of the 
rays are free. The lower anterior ends of the pectorals are closely approximated, 
without perceptible interspace. Vent anterior in position; a distinct though short 
anal papilla. Distance from vent to anterior end of pectoral base one-third its 
distance from front of anal. Head about 5 in length, equaling the depth. Dorsal 
about 65. Anal about 60. Longest specimen 85 mm. Uniformly black, including 
mouth and branchial cavity. 
The types of this species were taken by the Albatross in 1890 in the Gulf of Cali- 
fornia, station 3010; depth, 1,005 fathoms. A single young specimen taken in Alaska 
north of Unalaska Island, station 3332; depth 406 fathoms. 
93. Paraliparis cephalus Gilbert. 
Several more or less mutilated specimens were taken north of Unalaska Island and 
near Port Reyes, Cal.; stations 3225, 3330, and 3348; depths 284 to 455 fathoms. 
In this species the pectoral is inserted very low, its upper edge entirely below the 
eye. The lower jaw shuts within the upper, but the symphysis protrudes. The dis- 
proportion in size of head and body is more exaggerated in the young than in adults. 
In very small examples the head is almost spherical, diminishing abruptly to the 
very slender tail. No pseudobranchiz. 
94. Careproctus ectenes sp. nov. 
An extremely elongate form; depressed, but narrow anteriorly; the head as seen 
from above appearing shovel-shaped, with truncate snout. The nape is not elevated 
and the cheeks are not gibbous. The width anteriorly everywhere exceeds the 
depth. The mouth is inferior and transverse, overlapped by the short, depressed 
snout for a distance equaling diameter of pupil; the width of mouth nearly twice 
distance from symphysis of lower jaw to angle of mouth, the latter reaching vertical 
from about front of pupil. Teeth smail, weakly tricuspid, in narrow bands, the 
lower jaw containing 10 series in each half, the upper 11. Eye large, contained 1} 
times in total interorbital width, equaling length of snout, contained 34 times in 
head. Nostril with a very short tubular rim. Mucous pores large; texture of head 
and body firmer than in most deep-sea liparids. Gill-opening reduced to a narrow 
slit entirely above the pectorals, its width equaling one-half diameter of orbit. 
Opercle produced into a narrow spinous process, forming with its membranous flap 
a quadrate projection over middle of slit. 
Disk small, under the opercles and posterior part of cheeks, round in shape, slightly 
smaller than eye, its diameter one-fourth length of head. The vent is separated 
from disk by about two-thirds diameter of disk. Distance from vent to front of 
anal, one-half its distance from tip of snout. Head 54 in total length; depth of 
head, two-thirds its length; width of head, three-fourths itslength. Body extremely 
slender, its depth at middle of total length equaling diameter of eye; at base of 
caudal equaling two-thirds diameter of pupil. Dorsal beginning slightly behind axil 
of pectorals. Distance from origin of anal to tip of snout one-half its distance from 
base of caudal. Upper lobe of pectorals extending slightly past front of anal, the 
lower lobe to opposite the vent. Rays of lower lobe partly free. Dorsal with about 
51 rays, pectorals with 29. Color nearly uniform dusky-brownish; lighter on snout, 
belly, and under side of head. Mouth, gill-cavity, and peritoneum white. 
Three specimens, the largest 78 mm. long, from north of Unalaska Island, station 
3331; depth 350 fathoms. 
95. Careproctus colletti sp. nov. 
Closely related to C. reinhardti, from which it differs principally in the elongation 
and exsertion of the lower pectoral rays. These extend in all specimens to or nearly 
to the origin of the anal fin, and are always free for the greater part of their length. 
The head is blunt and heavy, with subvertical cheeks and bluntly rounded snout,
