Though we secured no examples ourselves, we have been able 

 to inspect a series obtained by Mr. Williamson at Huey Sak, Penin- 

 sular Siam. These are the same as birds from the Malay States 

 and must therefore be called A. f. torquatus Davison. We have ex- 

 amined the type of the latter from Pahang and, though in moult 

 and otherwise somewhat abnormal, it is indubital}^ an example of 

 this species. The Malayan form, however, is distiuguished from A. f. 

 fuscus Wagl., (type locality here restricted to Nepal) by smaller 

 size ; the wings of Nepal birds range from 122 to 128 mm. (average 

 125); of Malay States birds from 112 to 121 mm. (average 116.5 :
