ICHTHYOLOGICAL COLLECTIONS OF THE ALBATROSS. 441 
‘Family LIPARIDIDZ. 
91. Paraliparis holomelas sp. nov. 
Closely allied to P. cephalus and P. mento, differing in its uniform coloration, its 
more inferiorly placed horizontal mouth, and the distinctly included lower jaw. 
Head about 5 in length; depth about 6. Dorsal 58 to 61; anal 54. 
Head very large and heavy, with very broadly rounded snout and much swollen 
occipital and nuchal regions. The highest point is over upper opercular angle, 
from which the profile descends rapidly backward, though much less so than in P. 
cephalus. Snout very blunt, evenly rounded, very slightly projecting beyond the 
mouth, its width equaling the length of snout and eye, half the length of the head. 
Eye two-thirds interorbital width, 3; in head. Mouth large, horizontal, quite at 
lower side of snout, entirely below the eye; maxillary reaching a vertical slightly 
behind posterior margin of orbit, 1{ in head. Teeth acute, arranged in oblique 
series in each jaw, forming a very narrow band in mandible, a broader band in upper 
jaw. Very large mucous slits on head, 5 forming a series from tip of snout below 
eye and across cheeks, 6 along mandible and preopercle. Gill-slit wide, extending 
from above opercular flap nearly to middle of base of pectorals, its length 2} in that 
of head. Opercle forming posteriorly a narrow angular flap, projecting above base 
of pectorals. No pseudobranchiz. 
Vent below opercular flap, or somewhat in advance of that point, nearer to base 
of pectorals anteriorly than to first analray. Pectorals inserted very low, the base 
of upper lobe vertical, the base of notch and lower lobe horizontal, the upper end of 
base below the level of the eye. Pectorals with two wholly distinct lobes, the inter- 
space without free membranous margin, the skin of abdomen directly continuous at 
this point with that of shoulder girdle. On dissecting off the integument, however, 
the interspace between the lobes is seen to be provided with two or three short, 
widely spaced rays, as in all other species examined by us. The upper lobe is long, 
reaching beyond front of anal, with the rays close set, 18 in number, included in 
the membranes to their tips. Lower lobe consisting of five or six slender, almost 
filamentous rays, the longest reaching front of anal, all of them free to the base, 
without connecting membrane. Anterior (lower) ends of shoulder girdles approxi- 
mate, the rays separated by a distance equaling half diameter of pupil. Dorsal 
beginning above base of pectorals. 
Color uniformly black, including fins and lining of mouth and gill-cavity. 
Two specimens, 95 and 100 mm. long, from north of Unalaska Island; depths 406 
and 1,625 fathoms; stations 3308 and 3332. 
92. Paraliparis ulochir sp. nov. 
Differing from other Pacific species in the high insertion of the pectorals and their 
short horizontal limb, and from P. holomelas in having the fins not divided into two 
separate lobes. In general appearance greatly resembling P. holomelas, being also 
uniformly black in color, having the same broadly rounded snout, horizontal mouth 
with included lower jaw, and prominent occipital and nuchalregion. The maxillary 
reaches vertical just behind pupil and is contained 2; times in head. Teeth acute, 
in rather broad bands in both jaws. Snout broad and short, very slightly projecting 
beyond the mouth, the distance from tip of snout to front of eye 44 in length of head. 
Eye large, 3 to 3} in head, nearly twice the bony interorbital width. Gill-opening a 
narrow slit, restricted to area above base of pectorals, not longer than diameter of 
pupil. Opercle forming a short pointed lobe posteriorly, which touches base of 
upper pectoral ray. The head is denuded of skin, so the nature of the mucous pores 
can not be made out. 
Dorsal beginning above upper base of pectorals. Pectorals placed higher than in 
any other species known, its base describing a gentle even curve, convex backward, 
horizontal for a very short distance anteriorly. Its upper end is above level of pupil, 
and its lower anterior end is vertically below posterior margin of orbit. The upper
