Fig. 44. — Hexagrammos superriliosua (Pallas). 



We fail to find any differences in the supraocidar flap of this species and that of octogrammus. Dr. 

 Gilbert says it may Ik? distinguished from octogrammus liy the larger flap, smoother scales, and deeper 

 notch in the dorsal. The deeper notch in the dorsal and the complete fourth lateral line in supercili- 

 osus are tlie only marked differences we can find in our specimens. The specimen from Redfish Bay is 

 very highly colored with large white spots and bars, the spots being on base of pectoral and lower part of 

 body, the bars running irregularly over body and head. 



This species ranges from Bering Sea to Monterey Bay but is most aljundant norlliwp.rd. It grows to 

 a length of nearly 2 feet and is a palatable food fish. 



97. Hexagraramos lagocephalus (Pallas). (PL xv, fig. 2.) 



The home of this species is in the western parts of Bering Sea. It is known to occur about Bering, 

 Robben, and Itmup islands. The only specimen known from Alaskan waters was obtained at Attu in 

 1894 by the Albatross. It is no. 1665, U. S. National Museum, and is 19 inches long.

Three small examples, 4 to 5 inches long, from Port Townsend; onv (no. 02832), 12.5 inches long, 

 from Marrowstone Point. The species was also seen at Quarantine Station, Union Bay; Port Alexander; 

 Sitkoh Bay; and Loring. It was taken both in the seine and with hook and line. We also have a speci-
