Type, No. 28, 580, A. N. S. P. Lake Biwa at Matsubara, in Omi, 

 Japan. Jordan and Synder. From Stanford University. 



The above is the only example I have, and was found among a 

 number of small fishes received from Stanford University several 

 years ago. It appears to differ from Acheilognathus hiniantegus 

 (Gimther) and A. mesembrinum Jordan and Evermann, both from 

 Formosa, in the fewer anal rays. From A. cyanostigma Jordan and 

 Fowler, it differs in coloration. Both A. himantegus and A. longi- 

 pinnis (Regan), the latter from L. Biwa, differ in having barbels. 



(Brevis, short; analis, anal; with reference to the short anal fin.)

scales 34 in 1. 1. to caudal base, and 2 more on latter; 6 scales above 

 1. 1.; 5 scales below 1. 1.; 15 predorsal scales; head width If its length; 

 head depth at occiput about 1£; snout 3f; eye 3; maxillary 3|; 

 interorbital 2\; third dorsal spine \\; second anal spine If; least 

 depth caudal peduncle If; pectoral \\; ventral 1£. 



Body rather deep, well compressed, contour ovoid with greatest 

 depth anterior or about midway in preventral region, profiles similar, 

 and edges apparently all evenly convex. Caudal peduncle compressed, 

 least depth about equals its length.
