a little nearer base of caudal than the origin of pectoral, and the l)ase

 long as the ventrals, and its least depth about half th(Mr length. Lat-

Length, 5||- inches. 



This description from an adult breeding male takcMi at Tsuchiura, 

 wh(M'e we found it a))undant and highly colored. 



One of the most abundant of f Japanese Cyprinid;e. It is represented 

 in our collections by very immerous specimens from Tsuchiura, the 

 Kiiui River at Utsonomiya, the Yodo River at Osaka, the Chikugo 

 River at Kurume, the Yabe River at Funayado; abundant in the clear 

 water and very brilliant, Nagoya in Owari, Tana River at Tachikawa 

 (caught 1)y tame cormorants), Kawatana near Nagasaki, and Lake 

 Biwa at Matsubara. 



Breeding males are provided with numerous large and hard, horny 

 tubercles. They have the anal tin enormously developed, so that it 

 extends beyond the base of the caudal, and it is also sometimes fur- 

 nished with tul)ercles like those found upon the head. The colors of 

 these males are also nuich brighter than otliers in which the coloration 

 is more silvery. Young specimens are silvery and with distinct gray- 

 ish or pale brownish lateral bands posteriorly.
