JORDAN AND THOMPSON: FISHES OBTAINED IN JAPAN IN 1911. 231 
although the seales 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. Rhodews oryze may be taken as the type of a new genus Tanakia, separated 
from Rhodeus by the presence of a barbel. It is named for Shigeho Tanaka, the 
accomplished ichthyologist of the Imperial University of Tokyo.
