Thi' species lias been previously recorded (Bean 1882) as Pollachai* i-hiiimiirammns from Chuga- 

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

 Chemofski; (Jnalaska; and Wrangell. Under the same name byGilbert I 1895), from Captains Harbor, 

 Unalaska, and ai many stations in the shallow water of Bristol Bay and around the Aleutian islands. 

 Ohalaskaand St. Paul and St. George islands Jordan & Gilbert L899). Chignik Bay(Scofield L899). 



258. Theragra fucensis (Jordan & Gilbert . 



This species has not heretofore been recorded from Alaskan waters, though Scofield and Seale n»>k 

 in Chignik Bay a specimen which seems as near T. fucensis as /' chaleogrammus. li is verj probable 

 that the 2 species intergrade, i li< > northern specimens representing what is non known as T. chalco- 

 grammus, and the southern T. fucensis. It thi- i- so, the name T. chaleogrammus should be retained for 

 both. <>ur collection contains but a single example, do. 08122, a specimen lo inches long taken at 

 Loring by the Albatross in 1905.

 259. Eleginus 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 Puget Sound to the Alaskan 

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

 tion from the following places: Admiralty Island; Pert Alexander; Litnik Bay; Karluk: t'yak Bay; 

 Unalaska; Petropaulovsk, and Tareinski Harbor in Kamchatka, and stations 4202. 421?.. 4218 to 4220. 

 4268,4271.4272. 1275, 1277. 127s. 



The usual descriptions of Eleginus 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 vertebra?. We find that the following comparisons are helpful, and that 

 the species may be separated by their use: 



In pro rim us the first dorsal has 14 rays.
