This description from a specimen from the Yodo River in Osaka. 



Of this species, which is very abundant in all the rivers and lakes 

 of Japan we have many examples. They are from Junstii Lake in 

 Aomori, Hakodate, from the Sapporo Museum, Tsiu-hiura, Niigata, 

 Aomori, Sendai, the Yodo River in Osaka, the Iwai River at Ichino- 

 seki, and at Morioka, Misaki, Tokyo, Nagasaki, and Formosa. 



In this large series we are unable to distinguish more than one 

 species, subject to great variations. Li some examples the lower sur- 

 face of the body is mottled or spotted like the back. We also notice 

 many examples, as Dr. Giinther has observed, with deep bodies and 

 adipose layers along the rudimentary caudal rays, perhaps better fed 

 than usual.
