572 AVES. 



The measurements of the ahove specimen are as follows : — 



Total length 21-5 



Wing 16-7 



Tail 10-5 



Tarsus 2-1 



The bird in question is in the plumage which Mr. Sharpe describes (l. c.) as 

 the intermediate stage ; certainly it is not adult and has no crest to speak of. 

 Mr. Hume {I. c.) does not speak very positively as to the specific distinctness 

 of the Burmese Honey Buzzard, and it is probable that the bird from these 

 countries is intermediate between the ordinary Indian species and the large crested 

 form which inhabits Java.

This specimen approaches Elanus hypoleucus in appearance, as it shows a little 

 white near the base of the inner webs of the primaries. My specimen measures as 

 follows : — 



Inches. 

 Total length ......... 13-0 



Wing 10-5 



Tail 5-6 



Tarsus •••...... 1-.3 



These dimensions agree, very fairly, with those given by Mr. Sharpe in his 

 Catalogue.
