FORMOSAN RING-NECKED PHEASANT 



Phasiamis colchicus formosanus Elliot 



Names. — Subspecific : formosanus, of Formosa, the island home of this form. EngHsh : Formosan Ring- 

 necked Pheasant. 



Type. — LocaHty: Formosa. Describer: D. G. Elliot. Place of Description: Proc. Zool. Soc. London, 

 1 870, p. 406. 



Subspecific Characters. — The only character which can be trusted in the majority of cases is the 

 paleness of the mantle and flanks, these being deeper and warmer in torquatus. I have taken two birds well up 

 the Yangtze, which are even lighter than formosanus, but in these cases the green margins were very wide. In 

 Formosan birds I have known this green to be almost absent. The females of the two forms are identical. 



GEOGRAPHICAL DISTRIBUTION 

 The island of Formosa.
