are darker than either of the first two groups, and somewhat 

 browner in general tint. Those from Yunnan are much 

 darker and didler than either of the other three groups, and 

 the green is of a very sombre brownish tint, though the 

 skins avaihil)le are so bad that they may possil)ly U)ok duller 

 and browner than they should, 



Formosan and Hainan birds are both darker green above 

 than the adjaeent Cliinese birds, and are mueh browner and 

 duller below, but I can find little diiference in this res[)ect 

 between the birds of these two islands. 



The following are the names available for the Chinese 

 forms : —

Taking into consideration colour and size combined, we 

 seem to have the following well-marked eastern races in 

 addition to those already enumerated for India and 

 Burma : —

7'i/pe locaUtrj. Yunnan. 



A large bird with a wing averaging about 157 mm., and 

 with very dtdl dead-green pluuiage, this being es[)ecially so 

 on the lower parts. It cannot be confused with any other 

 subspecies, but the specimens at present available for exami- 

 nation are very poor. Birds from north and north-east 

 Shan States should be placed under this subspecies, though 

 their colouring is not so definitely dull and dark as that of 

 Yunnan birds. 



Habitat. Yunnan and northei'u Shan States.
