upper axilla of pectoral; head moderate, entirely naked; nape naked. 

 Upper teeth in a cardiforin band in front, thinning out behind. Lips 

 rather thin. Color nearly uniform, only relieved by the apparently lighter 

 hue of the scales and the somewhat darker margins of the fins; the scales 

 paler than the groundcolor, which is thus covered with whitish or silvery 

 specks. Bering Sea. Only the type known, its length 22 inches, from 

 which we have taken the above description, (concolor, uniformly col- 

 ored. ) 



Lycodes concolor, GILL & TOWNSEND, Proc. Biol. Soc. Wash., xi, 1897 (Sept. 17, 1897), 233, 

 Bering Sea, lat. 55 19' N., long. 168 n' W., Albatross Station 3608, (Aug. 12, 1895), 

 in 276 fathoms. (Type, No. 48764, U. S. Nat. Mus. Coll. Albatross.) 



2820. LYCODES ZOARCHUS, Goode & Bean. 



Head nearly 5f in total length ; depth 9; eye 4 in head = snout. D. 116; 

 A. 102; P. 19. Body covered with conspicuous embedded scales which 

 extend behind the dorsal and anal, leaving only a narrow naked margin 

 around these fins ; head and pectorals naked. A lateral line begins slightly 

 above the upper angle of the gill opening, rapidly curving downward and 

 extending along the lower part of the body not far from base of anal fin; 

 it can be traced above the anterior f of the anal. luterorbital distance, 

 measured on the bone, 4 in eye; nostrils placed close to upper lip and as 

 far from each other as from the eye ; maxillary reaching to vertical through 

 middle of eye; upper jaw 2^ in head; mandible nearly % head; mandible 

 with a conspicuous flap on each side, about as long as eye, beginning at a 

 distance from the symphysis equal to ^ length of eye; inner edge of man- 

 dible also with a slightly elevated ridge of skin. Length of intermaxillary 

 series of teeth equal to length of head ; length of palatine series nearly 

 equal to that of intermaxillary ; vomerines in a round patch; mandibular 

 teeth in 3 series; width of gill opening | length of head; ventrals in front 

 of base of pectorals, their length 8 in head. Distance between lower angles 

 of gill opening nearly length of head; origin of dorsal distant from the 

 head a space equal to ^ length of head, slightly behind middle of pectoral; 

 pectoral, when extended, reaching to about vertical from sixth dorsal ray; 

 longest ray of dorsal about length of head ; anal origin under seven- 

 teenth ray of dorsal ; vent under fifteenth ray of dorsal ; longest pectoral 

 ray contained about 9 times in total length. Lateral line distinct, ven- 

 tral in position, the median pores absent. Color grayish brown, lighter 

 on the belly and under surface of the head; sides irregularly mottled with 

 darker, a narrow dark edge at tip of first 4 dorsal rays. In a young exam- 

 ple (No. 39299, U. S. Nat. Mus.) the mottlings on. the sides are band-like, the 

 bands not extending below the middle of the body entirely. This example 

 is from lat. 44 26' N., long. 57 11' 15" W., 190 fathoms. The type of the 

 description is a specimen 366 mm. long, obtained by the Albatross in lat. 

 44 46' 30" N., 130 fathoms, off Nova Scotia. (Zoarclms, a synonym of 

 Zoarces; from Z,K>apKr)$, viviparous.)

 130 fathoms. (Type, No. 39298. Coll. Albatross.)
