 doubtfully, from Sitka. 



166. Trichodon trichodon Tilesius. 



Abundant about 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

Family BLENNIID^E. 



167. Bryostemma polyactocephalum (Pallas). 



Blennius polyactoeephalua Pallas, Zoogr. Kosso-Asiat., Ill, 179. (Kamchatka.) 

 Chirolophus japonicus Herzenstein, Melanges Biologiqiies, XIII, 1890/ 123. 



One specimen, 75 cm. long, from Kamchatka, agrees 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, flg. 2, and Jordan and Starks, Pishes of Puget 

 Sound, 1895, 841) are identical with the Kamchatka form. Alaskan specimens 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.
