The species has been previously recorded (Bean 1882) as Pollachius chatcogrammus from Chuga- 

 chik Bay and Refuge Cove, Cook Inlet; Pirate Cove and Humboldt Harbor, Shumagins: Iliuliuk; 

 Chernofski; Unalaska; and Wrangell. Under the same name by Gilbert (1895), from Captains Harbor, 

 Unalaska, and at many stations in the shallow water of Bristol Bay and around the Aleutian Islands. 

 Unalaska and St. Paul and St. George islands (Jordan i,t Gilbert 1899). Chignik Bay (Seofield 1899). 



258. Theragra fucensis (.lordaii i.t Gilbert). 



This species has not heretofore been recorded from Alaskan waters, though Seofield and Seale took 

 in Chignik Bay a specimen which seems as near T, fucensis as T. chalcogrammus. It is very probable 

 that the 2 species intergrade, the northern specimens representing what is now known as T. chalco- 

 gramnuis, and the southern T, fucensis. If this is so, the name T. chalcogrammus should be retained for 

 both. Our collection contains but a single example, no. 08122, a specimen 10 inches long taken at 

 Loring by the Albatross in 1905.

 259. Eleg^us navaga (Kolreuter). 



This codfish is common and at places abundant along the entire Alaskan coast. It is represented 

 in our collections by specimens from various localities extending from Ptiget Sound to the Alaskan 

 peninsula and across to Kamchatka. Forty-eight specimens, from 1.5 to 13 inches long, are in the collec- 

 tion from the following places; Admiralty Island: Port Alexander; Litnik Bay; Karluk; Uyak Bay; 

 Unalaska; Petropaulovsk, and Tareinski Harbor in Kamchatka, and stations 4202. 4213. 4218 to 4220, 

 4268, 4271, 4272, 4275, 4277. 4278. 



The usual descriptions of Elcginus navaga and Microgadus proximus refer to the same characters so 

 seldom, except in features in which they happen to be alike, that from these characters it is impossible 

 to compare the species, and the only way given to separate them is by dissection and a comparison of 

 the transverse processes of the vertebrse. We find that the following comparisons are helpful, and that 

 the species may be separated by their use; 



In proximus the first dorsal has 14 rays.
