S. TANAKA : 



Family Squalidae. 



2. Squalus mitsuklirii Jordan and Snyder. 

 Two specimens, from off Korsakoff (Aug. 19). 



The origin of the first dorsal spine is a trifle nearer that of the second 

 dorsal than the tip of the snout. The relative position of these three parts 

 as given in the original description of Jordan and Snyder a) does not agree 

 with that seen in the specimens before me, but these totally well with the 

 figure given by the said authors. 



Family Cobitidae. 



3. Orthrias oreas Jordan and Fowler. 



Numerous specimens from Chipesani (July 28 ; Aug. 23) ; 

 Vladimirofka (June 6 ; June 8) and Troitskoe (June 8). 



The labels attached to the specimens bear the name Dojö, a name 

 which in Japan proper is applied to Misguruns anguillicaiidatus (Cantor). 



Family Cyprinidae. 



4. Leuciscus hakuensis Günther. 



Numerous specimens from Chipesani (July 28 — Aug. 23) ; mouth 

 of the Susuya River (May 1 5) ; Lososei Bay (May 25).

Loc. Jap. name : Yachi ugui, Aburako, Aburako uwo.

 some specimens, but in others gray and scarcely showing mottlings.
