on hoth shores, in 15 to 130 fathoms, forming an important article of 

 commerce. Its range southward extends to the offshore bunks of Oregon. 

 In external respects we recognize no distinction between this species and 

 the common eastern codfish, except that the head seems larger. Here 

 described from a specimen 20 inches long, taken in the Straits of Fuca by 

 the Albatross. Concerning this species Dr. Gilbert observes: 



It has been frequently pointed out, and is Avell known to fishermen that 

 the Pacific codfish has a smaller air bladder or sound than the Atlantic 

 cod. Pending an examination of this question, which we are not now in 

 a position to make, we propose to recognize the Pacific fish as a distinct 

 species. {juaKpoi, long; K£0aA7^, head.)

Head 3^. D. 14 or 15-18 to 20-17 to 20; A. 20 to 22-18 to 19; V-6. This 

 species resembles the common cod {Gadus callarias), but differs from it as

 orbital width, longer barbel, more advanced position of ventral fins, and 

 a longer pectoral fin. Color dark, lilackish brown above, lighter below, 

 with yellowish marbliugs; the tip of the dorsal, anal, and caudal fins 

 black ; ventral Jiud pectorals dark brown or black, a dusky spot on the

This genus is distinguished from Gadus by its smaller mouth, the pro- 

 duced first dorsal fin, black lateral line, and especially by the great 

 enlargement of the bypocoracoid, which is dense and ivory-like. The 

 lateral line is always black, and the supraoccipital and other crests on 

 the head are largely developed. Food fishes of large size. (//*'Aas, black :
