Family BATHYMASTERID^E. 



163. Bathymaster signatus Cope. (Plate LXXVIII.)

 Stejneger and Grebnitzki on Bering and Medni islands.

 Wrangell. 



Family TRICHODONTID^E. 



165. Arctoscopus japonicus Steindachner. 



Two specimens from station 3652, off' Iturup Island, depth 14 fathoms. D., X 

 or XI, 13; A., 30 or 31. 



Originally described from the Gulf of Strietok, Japan, and recorded, perhaps 

 doubtfully, from Sitka. 



166. Trichodon trichodon Tilesius. 



Abundant aboat St. Paul Island, and often cast up by the surf; recorded by 

 Dr. Gilbert from Herendeen Bay and Bristol Bay, and by Dr. Bean from Shumagin 

 Islands, Unalaska, and Nunivak. Recorded by Stejneger from Bering Island. 



Family BLENNIID.^. 



167. Bryostemma polyactocephalum (Pallas). 



Blennius polyactocephalus Pallas, Zoogr. Eosso-Asiat., Ill, 179. (Kamchatka.) 

 Chiroloph us japonicus Herzensteiu, Melanges Biologiques, XIII, 1890, 123. 



One specimen, 75 cm. long, from Kamchatka, agrefes perfectly with Herzenstein's 

 detailed description above cited. There is no reason to doubt that this is the species 

 described by Pallas as Blennius polyactocephalus. We are not wholly satisfied that 

 specimens listed under this name from eastern Bering Sea and Puget Sound (see Bean 

 in Nelson's Report, p. 305, PI. XV, fig. 2, and Jordan and Starks, Fishes of Puget 

 Sound, 1895, 841) are identical Avith the Kamchatka form. Alaskan si^ecimens have 

 the posterior pair of supraocular cirri smaller than the anterior and have those of 

 the anterior pair united for often half or more than half their length. We know too 

 little of the variation within the species to warrant specific separation at present. 



Recorded by Dr. Gilbert from about the peninsula of Alaska. One specimen 

 obtained by us on St. Paul. Found by Stejneger and Grebnitzki on Bering and 

 Medni islands.
