beyond origin of anal, the shortest middle ray about that length ; a few 

 of the lower rays elongate and partly free from the membrane, the longest 

 equaling the length of the upper lobe; middle pectoral rays wide set, but 

 110 rayless interval between the lobes; pectorals converging to immedi- 

 diately behind symphysis of lower jaw, where their bases meet; anal 

 opening 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. Closely allied to Paraliparis (Hilgendorfia) membranacens (Giin- 

 ther), but with very heavy lower jaw, which projects beyond the upper. 

 The preuiaxillaries 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 forward. Length 3 inches. Oif the coast 

 of Oregon in deep water. (Gilbert.) (mento, having a projecting chin.)

 tross Station 3071, in 685 fathoms.

Head G; depth about 6; snout 3^; eye 3. D. 60; A. 55; pectoral 

 17-J-3; caudal 10. Snout broad, obtuse; iiiterorbital width equaling 

 length of posterior part of head; nostril about midway between eye and 

 tip of snout, in a very short tube. Five large mucous pores on each 

 side of snout, 3 smaller ones on cheek under eye, and 6 on mandible 

 and edge of opercular bones. Teeth minute, villiform, and in 2 

 series. Gill opening a very small slit, edged with black at upper angle of 

 pectoral. Origin of dorsal distant from snout 1^ times length of head; 

 tip of pectoral when extended about under second or third ray of dorsal ; 

 anal origin under ninth or tenth dorsal ray; length of middle caudal 

 ray 10| times in standard length; longest pectoral ray equaling dis- 

 tance from snout to dorsal; longest ray of the isolated portion of the fin 

 equaling that of middle caudal ray; distance of vent from tip of snout 

 nearly equal to length of head; vent a narrow slit placed horizontally, 

 directly under base of pectoral. Pyloric ca3ca 4 to 6. Color, anterior half 

 of body very pale, whitish; posterior half very light brown; snout, chin, 

 and edge of gill opening and region about the vent black. This species 

 has nearly the same number of rays in the dorsal and anal as are recorded 

 for P. bathybius, but the pectoral has 17 rays in the upper portion and 3 

 in the lower. The jaws are shorter than in P. bathybius; the form is more 

 elongate and the coloration is strikingly different, anterior half of the body 

 pale, almost whitish, while the snout, chin, and anal origin are black. 

 Length about 8 inches. The eggs of an example a little smaller than the 

 type have a diameter of about 3 mm. At the same time the ovaries con- 

 tain some eggs, which have not reached maturity, whose diameter is only 

 ^mm. The stomach is a stout subspherical receptacle, its greatest width 

 f- of its length. Gulf Stream, in deep water. (Named for Prof. Edward 

 Drinker Cope.)
