The Burmese and Siam birds, except those in the extreme 

 north of the Chin Hills and Yunnan, average much smaller than those 

 of China. Thus 14 Chinese males average in wing measurement 

 152 mm. and vary between 145 (1), 149 (1). and 158 mm. The 22 

 Siamese and Burmese birds average only 142, and vary between 136 

 and 151 mm. If, however, we leave out the birds of the Chin 

 Hills and Yunnan, which agree better with the Chinese birds in 

 size, the average is reduced to 141 mm., with a maxima of 149 

 mm., equal only to the smallest but one of the Chinese birds. 



A Saigon female is very small, having a wing of only 122 

 mm., another instance perhaps of specially small races in this area. 

 I can trace no difference in plumage between the Chinese and 

 Burmese birds correlating with that in size.

This specimen appears to belong to the typical Burmese and 

 Malayan form plumbipes, whilst others from the extreme east and 

 the north-east are perhaps referable rather to T. p. rostrata, the 

 Chinese form.

The wings of all three of these specimens vary between 5 in.

 coloured above, and are a pure slaty grey below. As a series, taken
