ICHTHYOLOGICAL COLLECTIONS OF THE ALBATROSS. 441 



Family LIPARIDID^. 



91. Paraliparis holomelas sji. nov. 



Closelj^ allied to P. cephalus aud P. mento, differing in its uniform coloration, its 

 more iuferiorly 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, evenlj^ 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, 3j 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 baud 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 2f in that 

 of head. Opercle forming posteriorly a narrow angular flap, projecting above base 

 of pectorals. No pseudobranchiic. 



Vent below opercular flap, or somewhat in advance of that point, nearer to base 

 of jiectorals anteriorly than to first anal ray. 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 s^iaced 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 lougest 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 aud 100 mm. long, from north of Unalaska Island; depths 406 

 and 1,625 fathoms; stations 3308 and 3332. 



92. Paraliparis ulochir sp. nov. 



Diftering from other Pacific sj)eciea 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 nuchal region. The maxillary 

 reaches A'ertical 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 4| in length of head. 

 Eye large, 3 to 3i in head, nearly twice the bony interorbital width. Gill-opening a 

 narrow slit, restricted to area ab(^ve base of pectorals, not longer than diameter of 

 pupil. Opercle forming a short pointed lobe jiosteriorly, 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
