18 MEMOIRS OF THE CARNEGIE MUSEUM 



58. Richardsonius hakuensis (Glinther). "Ugiu." 



Kanko River, Fusan, Chinnampo (No. 4360a-c) (No. 4514a-c). Abundant. 



Breeding males with two rather narrow orange stripes on each side from 

 head to tail, one along the back and one along the side of the belly. Since, 

 according to Professor Cockerell, none of the American or Japanese species 

 usually referred to Leuciscus are congeneric with the European dace, Leuciscus 

 leuciscus (Linnseus), we adopt for the group the oldest of the American names. 

 The scales of Richardsonius are said to differ materially from those of Leuciscus. 



59. Richardsonius brandti (Dybowsky). 



Chinnampo (No. 4110), Gensan (Jordan & Starks, as L. taczanowskii) . 

 According to Dr. Berg brandti and taczanowskii are identical. 



60. Richardsonius semotilus (Jordan & Starks). 

 Fusan (Jouy); Gensan (Schmidt).

61. Richardsonius jouyi Jordan & Snyder. 



(Leuciscus dorobae Ishikawa.) 

 Sasuma, island of Tsushima. 



62. Hemitremia lagowskyi (Dybowsky). 

 Gensan (Schmidt). 



According to Professor Cockerell the scales of the European species of 

 Phoxinus differ generically from those of the East Asian and American forms 

 referred to Phoxinus. We therefore use the name Hemitremia for the American 

 and Japanese forms. 



63. Acheilognathus coreanus Steindachner. 



Seoul (Steindachner). 



64. Acheilognathus signifer Berg. 



Pung-tung (Herz).
