olive along sides, these irregular on their edges, about ^ width of eye, 

 with uneven edges ; a trace of a third similar stripe below anteriorly, the 

 stripes very irregular; back mottled. Dorsal plain dark olive; pectoral 

 quite dark; lower fins ashy; caudal ashy olive. Bering Sea and neigh- 

 boring waters, probably south to Sitka and the Kurils. Our specimens 

 from Unalaska, Robben Reef, Komandorski and Pribilof islands and 

 Bristol Bay. Excessively common throughout Bering Sea, swimming 

 near the surface, and furnishing the greater part of the food of the fur 

 seal. This animal rarely catches the true .codfish, which swims nearer 

 the bottom. Length 3 feet. (xaXnoc,, brass; ypaf.i/.if}, line.)

(WALL-EYED POLLACK; PUGET SOUND POLLACK.) 



Head 3* in body; depth 5|. D. 10-13-16 to 11-15-16; A. 16-19 to 19-19; 

 eye 4 in head; maxillary 23 ; pectoral 1?; longest caudal ray 2. Body 

 elongate, not greatly compressed; mouth large, the maxillary reach- 

 ing to below middle of eye; jaws with minute, sharp, curved teeth, the 

 outer series enlarged ; teeth on vomer, palatines toothless; lower jaw pro- 

 jecting, a very small barbel under its tip; interorbitjtl space wide, very 

 slightly and evenly convex, wider than the diameter of eye; nostrils 

 much nearer eye than tip of snout, the posterior much the larger; head 

 almost entirely covered with small scales ; gill rakers numerous, the long- 

 est as long as pupil, about 5 -{-27 in number. Distance of origin of first 

 dorsal from snout 3^ in body; first rays of first dorsal reaching far past 

 the ends of last rays where fin is depressed ; first rays of other dorsals and 

 auals scarcely reaching the base of last rays ; caudal slightly forked or 

 subtruncate when spread, the lobes subequal; end of pectoral reaching to 

 front of anal ; ventrals inserted in front of base of pectoral in distance 

 a little more than diameter of eye, ending in a filamentous point. 

 Color nearly plain sooty, with no distinct lateral bands, and with gen- 

 erally only a trace of a pale lateral streak along the side ; on the head 

 some diffuse dark spots ; fins all dusky. The band of teeth in the pre- 

 maxillary is wider than in Theragra dial co gramma, and the band is widened 

 at the anterior end; the body is shorter; eye smaller; color darker; fins 

 not so high ; caudal not so deeply forked. Pacific coast, from Vancouver 

 Island to Monterey, abundant in Puget Sound; probably northward to 

 Kadiak, replacing T. chalcogramma to the southward. This form may 

 intergrade with Theragra chalcogramma, though the original types seem 

 well separated. Little is known of its range to the northward. Scofield 

 and Scale took a specimen in Chignik Bay in northern Alaska, which
