Anguillidae. 

 19. Anguilla japonica (Schlegel). 



Ixical name : Unagi. 



I have no specimens of this species from the district, hut from 

 several reports, it is clear that the species occurs in the province. 



Salmonidse. 



20. Salvelinus malma (Walbaum). 



Local name : Iwana. 



Twelve specimens, the largest 25 cm. long as measured to ro >t 

 of middle caudal rays. 



The whitish spots and the extension of maxillary are variable 

 to some extent in our specimens, so that Salvelinus kundscha (Pallas) 

 and Salvelinus pluvius (Hilgen lorfj seem to me to he merely local 

 variations of malma. 



21. Oncorhynchus masou (Brevoort). 



Local name: Ameuwo ; Amenomvo ; Ameo ; Amego; Yamame ; Amcmasu ; 

 Endokko ; Amcmasu ; Kokurc : Ma.su ; Masunoko. 



Numerous specimens, the largest heing 26.5 cm. long as measured 

 to root of middle caudal rays.
