Color light rose rt'tl on hody jiiid liiis, tlio abdoinen usiiallv dusky. 

 Inner face of ijectoinls, the caudid, the. jiostcrior jiortions <»l«[tirsal and 

 anal, and the inside of month an<l ^ill openings, black. The peritoneum 

 is silvery, witli more or less hlacksi>ecking, sometimes nearly black. 



Several specimens, the longest about inches long, IVom Stations 

 2S40, 2S1H, 2892, L'lLM, and oOKI, in depths from 178 to 3:i\) fathoms oU" 

 the coast of California and Oregon. 



28. Paraliparis cephalus sp. im>\ . 



Mend very large, high, and comi>ressed, the upper profile descending 

 in a strongconvexcnrve behind the o(;ciput; bo<ly tapering jtosteriorly 

 to a very narrow thread-like tail. Sides of head vertical or iui'lining 

 inwaids below. Height of head twice height of body opposite origin 

 of anal. luterorbital space transversely rounded, its width slightly 

 less than length of snout and eye. Eye of moderate size, 4 in head, 

 without vertical range. Month oblicpie, the })remaxil!aries but little 

 below lower margin of eye. Lower Jaw longest, with the tip protrud- 

 ing. Maxillary reaching vertical from the posterior margin of the eye, 

 slightly more than the length of the head. 



dill slits narrow, confined to a region above the base of the pectorals. 

 The membrane connecting the branchiostegal rays with the shoidder 

 girdle very delicate anil easily ru[)tured, broken in all but one of the 

 spe(!imens. The vent is distant less than a diameter of the orbit from 

 this point, being below the front margin of the preopercle. 



Teeth in narrow bands iu both Jaws, the teeth of the bands arranged 

 in obli(pie series running outward and forwards. Palate toothless. 



Head 4^ in length, greatest depth (at oin-ipnt) 4=,'. 



Pectoral small, without about fourteen rays, the upper ones closest 

 and forming a projecting lobe, whiuh extends backwards to beyond 

 origin of anal. The succeeding rays are shortene<l and wide-set, and 

 have the tips free from the membrane. The tin is somewhat mutilated, 

 but is apparently notched, not however to the base, the median por- 

 tion having wide-set rays. Upper margin of pectorals on a level with 

 tip of lower Ja\r. 



The dorsal begins slightly behind the head, and the first i:iv nfiuial 

 is under tie eighth of the dorsal. 



Color light reddish, the abdomen blue-black. Inside of mouth and 

 gill opening white. In the smallest specimens, 2 inches long, the color 

 is dusky on head and bo<ly, and on inside of month. Longest specimen 

 ,'>A inches. 



This species dilVers from I'((n(lij)ari.'< mcmhrandrrus in the structure 

 of the pectoral (ins and their much fewer rays, in the position of the 

 vent (below the posterior margin of the orbit in wcnihninaceus), the dif- 

 ferent outline of head, and iu the larger more oblique mouth. In 

 none of the specimens of cephnlns are there fin-folds extending forwards 

 from front of dorsal and anal, as described iu mcmhranmruii.
