BULLETIN OF THE BUREAU OF FISHERIES. 



Sebastodes alutus (Gilbert). 



List of Stations. 



Vicinity of Attu Island; the Komandorski Plateau. 



Sebastodes glaucus (Hilgendorf). 



One specimen, 445 mm. long, was taken with hook and line in Preobrazhenskoi Bay, Medni Island. 



Dorsal xiv-15; anal iii, 8. Lateral line with 52 tubes. Gill rakers 9-I-27, the longest three-fourths 

 diameter of eye. Color in life pale brassy, darker on all the fins, especially the caudal; below white, 

 the large ventral scales pearly, marbled and clouded with dusky; sides with 6 vertical bars, the anterior 

 one above the pectoral; head with indistinct dusky bars radiating from eye; snout and chin blackish. 



HEXAGRAMM1D,€. 

 Hexagrammos octogranunus (Pallas). 



Unalaska, Atka, Attu, Medni, and Bering Islands, and Avatcha Bay, Kamchatka. 



Hexagrammos stelleri Tilesius. 



Avatcha Bay, Kamchatka. 



Hexagrammos superciliosus (Pallas).

COTTID^. 

 Icelinus borealis Gilbert. 



Stations 4777 and 4779, Petrel Bank; 4782 and 4784, near Attu Island, Bering Sea; depths 43 to 135 

 fathoms. 



Icelinus (including Tarandichthys) differs from all other North American cottoids in having only 

 two articulated rays in the ventral fins. In this respect it agrees with certain Japanese genera (Sllengis, 

 Schmidtina, Danuna, Ricuzenius), among which must be sought its nearest allies. 



Astrolytes fenestralis (Jordan & Gilbert). 



A single specimen from tide pools at Unalaska. 



ARCHAULUS, new genus. 



Head and body compressed. A series of spinous plates along the lateral line; a double series of 

 plates along the base of the dorsals, widening anteriorly into a band and uniting with its fellow of the 

 opposite side in front of the dorsal fin; head naked. Gill membranes united, free from the isthmus. 

 No pore behind the last gill arch. Teeth on jaws, vomer, and palatines. Preopercle with four simple 

 spines. Ventral fins with one spine and three rays. 



Closely allied to Archisies, but with the dorsal row of plates double, the anterior widened portion 

 filling entire space between base of dorsal and lateral line and continuous with its fellow across nape, 

 which is entirely invested; and with four distinct preopercular spines. 



Archaulus, Gilbert and Burke, new genus of Cottidse; type Archaulus biseriatus, new species. 



Archaulus biseriatus, new species. (Fig. i.) 



Type a male, 154 mm. long, from station 4778, Petrel Bank, Bering Sea; depth 43 fathoms. 



Head 27 hundredths of total length to base of caudal; depth 27; length of snout 9.5; length of 

 maxillary 9.5; diameter of orbit 7.1; interorbital width 4; least depth of caudal peduncle 7; greatest 

 width of head 16.5; longest dorsal spine 20; length of dorsal base 71; length of anal base 47; length of
