although the scales are modified throughout in a continuous series. The tip of each 

 scale is emarginate and a groove lies along the center of the scale where the tube 

 should lie. This species, with Rhodeus miobuta Tanaka, has barbels as in Acheilo- 

 gnathus. Rhodeus ory zee may be taken as the type of a new genus Tanakia, separated 

 from Rhodeus by the presence of a barbel. It is named for Shigcho Tanaka, the 

 accomplished ichthyologist of the Imperial University of Tokyo.
