 69. Sebastolobus alascanus (Bean). 



The collection contains 11 specimens of this species, the localities represented being stations 4238 

 to 4241 (Behm Canal) and 4302 ( Sumner Strait, off ShakanV The depths range from 169 to 256 fathoms. 

 The specimens range in length from 3.4 to 23 inches. 



Dorsal xvi in 8 specimens, .xvii in 3. In two small examples (3.4 and 5 inches total length) the 

 black spots on the spinous dorsal are quite distinct and the pectorals are marbled with black and white. 

 The ventrals also are dusky, and the soft dorsal of the smaller specimen is dusky, and has 3 or 4 small 

 roundish white spots. Two adults (nos. 2878 and 2879) taken at station 4238, in Behm Canal, were, 

 in life, bright rose-red all over, paler below, especially on lower parts of head; fins all red; caudal with 

 some black on outer parts of membranes; pectoral also with some black on interradial membranes; 

 inside of opercle rose-color. 



Originally described by Bean (1891) from Albatross station 2853, off Trinity Islands. Recorded 

 also by Gilbert (1895) from stations 3227, 3324, 3330 to 3332, and 3337 to 3340, in Bering Sea, north of 

 Unalaska Island, or in the north Pacific, southeast of Unimak Island. 



This species reaches a length of 2 feet or more. Its range extends from California to Bering Sea. 

 It is usually found in rather deep water, 100 to 800 fathoms. Its flesh is palatable and the species should 

 be of some value as a food fish.
