THE BIRDS OF SOUTH-WEST AND PENINSULAR SIAM. 215 



in the rest the breast-band varies from chestnut-black to 

 blackish chestnut. Swann seems correct in stating that B. I. 

 hrurinana has been arrived at through comparing adult Bur- 

 mese birds with immature Indian ones.

It is probable that all the specimens mentioned are ex- 

 amples of Cerchneis tinnunculus dorriesi, the Siberian 

 Kestrel, which Swann states has a much longer tail than in 

 other forms (c^ 172-194; 2 178-200 mm.). 



Other races to be considered in connection with S. W. and 

 Peninsular Siam, having regard to the distribution given by 

 Swann (Syn. Accip. ed. 2, p. 216), are G. t. interstinctus 

 McClell. (of which saturatus Blyth is a synonym), the 

 Assamese Kestrel, visiting the Malay Peninsula in winter ; 

 and perhaps C. t. japonicus (Temm. and Schleg.), the Japanese 

 Kestrel, known in winter from Hainan, the Philippines and 

 Borneo.

Pernis apivorus orieatalis, Tacz., the Siberian form of the 

 Crestless Honey Buzzard, may occur, as it travels south as far 

 as the Sunda Islands in winter. 



The common bird in the Malay Peninsula is undoubtedly 

 P. pt. ptilorJiynchus ; but it may be visited in winter by the 

 North Indian race, P. pt ruficollis, and the Siberian form, 

 P. a. orientalis.
