A collection of Lake Biwa fishes, which had been made in the 

 interval of Sept. 1906 to Sept. 1907 by Mr. Shimazu, a naturalist in 

 Kyoto, was presented by that gentleman to the Imperial University 

 of Tokyo. These material, together with those which were collected 

 by Mr. J. Nakanishi in Jan. — June, 1898, in the same locality and were 

 since stored up in the University collection, will be noted upon in this 

 paper. A species is apparently new to science, for which I propose 

 the n unc AchcilogiiatJuts shimazui. At the end I append a list of all 

 the fish species that have thus far become known from Lake Biwa.
