The Fresh Water Fishes of the Island of Formosa. 315 



21. Chanodichthys tnacrops. 24. Rhinogobius candidius. 



22. Culler aokii. 25. Rhinogobius taiwanus. 



23. Channa formosana. 26. Rhinogobius forniosaniis. 



At present the percentage of peculiar species is extraordinarily 

 high. But it is quite possible that some of them may be found in 

 adjacent regions, probably in Southern China, and sooner or later a 

 slight reduction may have to made. 



Of the above-mentioned twenty-six species, the relationship of five 

 is somewhat dubious, namely, Ilemimyzon formosanus, Spinibarbus 

 hollandi, Pararasbora moUrechti, Candidia barbata, and Phoxiscus 

 kiknchii. One is very closely related to a species from the interior 

 of Hainan, namely Scaphesthes tamusuiensis. Five have their nearest 

 relatives in China, four- in Corea, one in Amur Province, and eight in 

 Japan. There is no record regarding near relatives of the remaining 

 two, namely, Barbodes paradoxus and Capoela snyderi. But the 

 majority of the fishes which belong to these genera are distributed in 

 British India, Indo-China, and China. Therefore, there is no doubt 

 with reference to their relationship with the continental forms.
