562 NEW FISHES FROM PACIFIC COAST GILBERT. 



Several specimens from stations 2839, 2892, 3070, and 3071, in 284 to 

 685 fathoms ofl" the coast of California and Oregon. 



29. Paraliparis mento sp. uov. 



Closely allied to Faraliparis menihranaceus Giinther, but with very 

 heavy lower jaw, which projects beyond the upper. The premaxillaries 

 are high, on the level of the lower rim of the orbit, and the form is 

 much more elongate. The pectorals are inserted much lower, and the 

 vent is farther forwards. 



Head 5f in length without caudal, equaling the greatest depth. Eye 

 a trifle less than interorbital width, greater than snout, 3 in head. 

 Mouth oblique, with lateral cleft, the maxillary reaching slightly 

 beyond the middle of the orbit, half as long as the head. Chin very 

 prominent, the mandible with a wide membranous border, which forms 

 anteriorly a broad free fold over anterior portion of base of pectorals. 



Teeth in both jaws comparatively long and slender, not tricuspid, 

 arranged in bands, those in upper jaw at least in oblique rows, as usual 

 in Liimrids. Nostril with a single opening and without tube. Gill 

 opening but little wider than diameter of eye, confined to region 

 above base of pectorals. 



D. 57 5 A. 43; P. 16. 



Pectorals inserted very low, their upper rays below level of angle of 

 mouth. The base is almost horizontal, and tlie anterior ends of shoul- 

 der girdle form i>rominent projections below tips of mandibles. The 

 fins are very deeply notched, the upper lobe extending slightly beyond 

 origin of anal, the shortest middle ray about one-fourth that length ; 

 a few of the lower rays elongate and partly free from the membrane, 

 the longest equaling tbe length of the upper lobe. The middle pec- 

 toral rays are wide-set, but there is no rayless interval between the 

 lobes. The two pectorals converge to immediately behind symphysis of 

 lower jaw, where their bases meet. 



The anal opening is vertically below middle of orbit. 



Dorsal beginning a trifle behind the upper angle of gill opening, the 

 anal origin under its eighth ray. 



Skin loosely investing the head and body. 



Light reddish, made dusky by minute dark dots. Abdomen blue- 

 black. Mouth and gill cavity light or dusky. 



A single specimen, 3^ inches long, from station 3071, in 685 iathoms 

 off' the (joast of Oregon.

30. Tiachyihynchus helolepis sp. uov. 



Snout depressed, flat, narrowly triangular, tapering to a sharp point, 

 its lateral ridges continuous backwards over suborbital chain and across 

 cheeks. Interorbital space wide and flat. Ethmoidal ridge not ju-omi- 

 nent. Snout 2h in head, its greatest width If in its length. Eye large, 

 equaling interorbital width, 4 in head.
