 teeth in jaws much enlarged, canine-like. Palatines toothless. Fin membranes

65. Hexagrammoa superciliosus (Pallas). 



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

 Eecorded by Dr. Bean from Kadiak, Unalaska, and Attn; by Dr, Gilbert from 

 Unalaska, Makushin, and Ohernofski harbors, and by Stejiieger from Bering Island. 

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

 Sexagrammos superciliosus. We have examined the types. 



66. Fleurogrammus monopterygius (Pallas). Atka fish. 



Obtained by us at St. Paul, where it is rare. It is common about Atka and Attn, 

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

 from Unalaska and Attn. Taken by Stejueger 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. 



Eecorded from Kadiak. 



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 provided with t\fo 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 (Eeinhardt). 



Eecorded 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.

Described from near Unalaska.
