TWO NEW CYPRINOID FISHES FROM FORMOSA. 

 BY MASAMITSU OSHIMA. 



By courtesy of Mr. Moichiro JMaki, of Taihoka Normal School, 

 the author was able to examine the collections of Formosan fresh- 

 water fishes made by his students during the summer of the year 

 1919. Among them two species of Leuciscus were found which are 

 apparently new to science. Unfortunately, there are no records with 

 regard to their type localities. It is certain, however, that they 

 were obtained in the mountain streams of central Formosa, because 

 other species preserved in the same bottle, that is, Salmo formosanus 

 and Liobagrus formosamis, are not found from in other places than 

 the tributaries of the Taiko and Taito Rivers.
