This description from an example from Kawatana, on Omura Bay. 



Fresh waters of Japan; our very numerous series from Aomoii, 

 Kitakami Kivei, lake near Sendai (collection Awano), Niigata in Ech- 

 igo (collection Eitaro lijima), Tamagawa in Tachikawa, Kinu, River, r 

 in Utsunomiya, Iwai River in Ichinoseki, Tokyo, Tsuruga, Nagoyaini 

 Owari (collection K. Otaki), Yodo River at Osaka, C-hikugo River ati 

 Kurume, Kawatana, and Lake Biwa. 



In this series great variation occurs. The examples from Lake 

 Biwa are very nuich more elongate and have the brown l)lotches on 

 the sides mergc^l into a continuous longitudinal band, and the space 

 between it and the superior dorsal row of spots, which is also more or 

 less continuous, light and plain colored, like the lower surface of the 

 body. The colors are altogether more distinct and sharpl}^ defined, 

 and the dorsal and caudal are with only one or two blackish bars, i 

 This form has been described from near Nagasaki under the namei 

 of '"Cohitis tsenia japonica'''' by Schlegel. As the name japonlca isii 

 preoccupied in Cobitis^ Jordan and Snyder have sulistituted for it the 

 name of Cohlt/.n hlivae. But there seems to l)e no permanent value in 

 these differences in color and form. Examples from Kawatana andji 

 the Chikugo River at Kurume, collected together in both localities,-; 

 contain ])oth this striped form and those with the lateral bands broken' 

 up into spots. 



We can not lind any difference between the Japanese species and the 

 Loach of Europe, and hence retain for it the ancient name of (ohitlS' 

 tmnia. Should the Asiatic species prove distinct, the name Cobitu-\ 

 sinenHh may be retained for it.
