this, the collections give a fair understanding of the fishes of Formosa. 

 It is evident in the first place that the marine species are essentially 

 those of that part of the coast of China having similar physical con- 

 ditions. The freshwater fishes are derived from China, but are largely 

 distinct as to species. 



Compared with Japan and India, the following statistics may be 

 interesting: 



Species. 



Common to Formosa and Kiusiu 30 



Common to Formosa and Hindostan 77 



Common to Formosa, Kiusiu, and Hindostan 37 



It is evident that the faunal i-elations of Formosa are closer with 

 those of Hindostan than with even the southernmost of the Japanese 

 islands, Kiusiu. ' As for the main island of Japan (Hondo), fcAV of its 

 characteristic species extend their range south of the Tropic of Cancer; 

 and few of them reach even to the Kiukiu Archipelago.
