Indo-Malayan region. Siishkin '^ upholds macronyx, however, but 

 his diagnosis is not very convincing and he gives no measurements. 



Five a(]ults of plexus from the Kolyma measure: Vv'ing, 77-83 

 (79.4); tail, 65-70 (67.7); culmen, 12.5-13 (12.8); hind claw, 10.5-11 

 (10.9) mm. Seven from Siam: Wing, 76-84 (80.4); tail, 67-72 (69.7); 

 culmen, 13-13.5 (13.1); hind claw, 10-13 (11.2) mm. 



As I have mentioned before,'^ it seems to me that Budytes thunhergi 

 belongs to a diil'erent form group from B. jiavus and that such an 

 arrangement would certainly show their relationship and explain 

 their distribution better. 



B. t. plexus breeds in northeastern Siberia and migrates through 

 eastern China to Indo-China, Siam, and Burma to winter. In Siam 

 it has been recorded scatteringly practically all over the country and 

 in Peninsular Siam as far south as Patani.'* Deignan -^ records it as 

 not uncommon at Chiengmai during the cold weather.
