[Eeceived March 25, 1879.] 



Lycodes pacificus, n. sp. 



Vomerine and palatine teeth none. Coloration uniform yellowish 

 grey. The body is scaly, the head and the pectorals naked. The head 

 is contained four times and six tenths, the height of the body nine 

 times, in the total length. Lateral line very indistinct.

Had. Japan (Mus. Berol.). 



Body moderately elongated ; the height of the body is one half of 

 the length of the head, which is contained four times and six tenths 

 in the total length. The snout is only a trifle longer than the eye, 

 which is one fourth of the length of the head ; the upper maxillary

extending to below the anterior part of the eye. Teeth only in the 

 jaws, forming a single row behind ; in the upper jaw there is a 

 double series in front, in the lower jaw three or four series. The origin 

 of the dorsal is only a little behind the vertical from the root of the 

 pectorals ; it has about 92 rays, which are divided to their bases. 

 The anal has 71 rays, and commences below the vertical from the 

 seventeenth ray of the dorsal. The rays of the caudal are exceedingly 

 close together and slender ; their number seems to be 6 on the dorsal, 

 and 5 on the ventral side, as in other species of Lycodes. The 

 pectorals are broad and rounded, and have 18 rays; their tips do 

 not reach forwards to the eye. Along the jaw is slightly visible the 

 usual row of shallow impressions, which correspond with the holes 

 in the maxillary bones, as in the Lycodce generally. The body and 

 the bases of the dorsal and the anal are scaly ; the head, the pec- 

 torals, and the ventrals are naked. The distance of the vent from 

 the snout is contained twice and a half in the total length. One
