distance from tip of siiout to front of eye 4 in length of head. Eye large, 



3 to 3 in head, nearly twice the bony interorbital width. 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 2 separate lobes. In general appearance greatly resembling P. Iwlo- 

 melas, 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 vertical just behind 

 pupil and is contained 2-p - times in head. Teeth acute, in rather broad 

 bands in both jaws. Gill opening a narrow slit, restricted to area above 

 base of pectoral, not longer than diameter of pupil. Opercle forming a 

 short, pointed lobe posteriorly, which touches bae 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 ; pectoral 

 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 above level of pupil, and its lower anterior 

 end vertically below posterior margin of orbit; upper and lower rays of 

 the fin fine and crowded, the middle third of the base being occupied by 



4 or 5 more widely spaced rays ; the fin with 25 rays, of which 9 belong to 

 the lower lobe; upper lobe extending beyond origin of anal fin; none of 

 the rays free; lower anterior ends of pectorals closely approximated, 

 without perceptible interspace. Vent anterior in position, a distinct, 

 though short, anal papilla. Distance from vent to anterior end of pecto- 

 ral base ^ its distance from front of anal. Longest specimen 85 mm. 

 Uniformly black, including mouth and branchial cavity. Gulf of Cali- 

 fornia and Bering Sea north of Unalaska Island, in deep water. (ot)/to,

Rhinoliparis, GILBERT, Kept. U. S.Fish Comm. 1893 (1896), 445 (barbulifer). 



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

 Avhich 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 pec- 

 torals. Teeth acute, in a broad band in each jaw, arranged in oblique 

 series within the band. Deep sea. (/6zV, snout; Liparis.} 



2479. BHINOL1PARIS BARBULIFER, Gilbert. 



Head 5|; depth 7 ; eye nearly 3. 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,
