65. Hexagrammos superciliosus (Pallas). 



Seen by Dr. Jordan at Captains Harbor, Unalaska, where it is abundant. 

 JBecorded by Dr. Bean from Kadiak, Unalaska, aud Attn; by Dr. Gilbert from 

 Unalaska, Makusliin, and Cbernofski harbors, and by Stejneger from Bering Island. 

 Hexayrammos scaber Beau from Amchitka and Unalaska is evidently the young of 

 Hexagrammos superciliosus. We have examined the types. 



66. Pleurogrammus monopterygius (Pallas). Atka fish.

 and it is said to be occasionally taken as far east as Belkofski. Recorded by Dr. Bean 

 from Unalaska and Attu. Taken by Stejneger at Saranskaya, Bering Island.

67. Ulca marmorata (Bean). 



Eecorded by Dr. Gilbert from about Unalaska; by Dr. Bean from Sitkalidak 

 Island (near Kadiak). 



68. Hemitropterus cavifrons Lockington.

69. Icelus spiniger Gilbert. 



Stations 3643 and 3644, off Povorotnaya, Kamchatka, in 100 and 96 fathoms. 

 Originally described from Bristol Bay and about Unalaska. 



Females of this species seem more spinous than males. The spines on supra- 

 orbital ridge are higher, the suborbital stay is frequently lorovided with two low 

 spinous points, and the top and sides of head as well as the bases of the dorsal series 

 of spinous plates may be thickly beset with small prickles. 



70. Icelus bicornis (Reinhardt). 



Recorded from Bristol Bay and stations to the westward, as well as from Green- 

 land and the North Atlantic, if the Pacific species is the same, which is doubtful.
