442 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



and lower rays of the liu are line and crowded, the middle third of tlie base being 

 occupied by 4 or 5 more widely 8i)aced rays. The tin 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 

 <listauce from front of anal. Head about 5 in length, equaling the depth. Dorsal 

 about G5. Anal about (50. Longest specimen 85 mm. Uniformly black, including 

 mouth and branchial cavity. 



The types of this species were taken l)y 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 pseudobranchije. 



94. Careproctus ectenes sp. nov. 



An extremely elongate form ; depressed, but narrow anteriorly ; the head as seen 

 from above ai)pearing 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 small, weakly tricuspid, in narrow bands, the 

 lower jaw containing 10 series in each half, the upper 11. Eye large, contained IJ 

 times in total interorbital width, equaling length of snout, contained 3^ times in 

 head. Nostril with a very short tubular rim. Mucous pores large; texture of head 

 and body firmer than in most deep-sea lijiarids. 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-h.alf its distance from tii> of snout. Head 51 in total length; depth of 

 head, two-thirds its length; width of head, three-fourths its length. 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. 



Tliree specimens, the largest 78 mm. long, from north of Unalaska Island, station 

 3331 ; depth 3.50 fathoms. 



95. Careproctus colletti sp. nov. 



Closely related to C. reinhardii, from which it differs principally in the elongation 

 and exscrtion of the lower pectoral rays. These extend in all specimens to or nearlj' 

 to the origin of the anal (in, and are always free for the greater part of their length. 

 The head is blunt and heavy, with subvertical cheeks and bluntly rounded snout,
