Oustalet {^loc. cit.) states that one of the types of i^. t. tristis 

 Lesson was collected in Cochin China by Diard in 1824, 

 while the other was sent from Bengal by Duvaucel in 1825. 

 Cochin China and Hainan birds are undoubtedly identical, 

 so that if tiie first-mentioned specimen is taken as the type, 

 it woukl be necessary to re-name the western bird. To 

 avoid this inconvenience, we here definitely select Bengal 

 as type-locality of R. t. tristis. 



The above series, when compared with a similar number 

 from Siam and the Malay Peninsula, show a progressive 

 increase in the size of the bill as we proceed west and soutii, 

 but the difference is not sufficient to constitute an inter- 

 mediate subspecies. In the southern part of the Malay 

 Peniusula, the bird is strictly confined to high altitudes, 



* Probably wrongly sexed.
