ON THE RUBY-CHEEK WITH DESCRIPTIONS OF 

 THREE NEW SUBSPECIES. 



Having assembled a large series of Chalcoparia 

 singalensis from Indo-China and Malaysia I take the oppor- 

 tunity to review the races occurring on the mainland and 

 the large islands. 



Beginning with the northern specimens of the series 

 1 recognise the following forms : — 



1. Chalcoparia singalensis koratensis Kloss. 



Kloss, Ibis 1918, p. 218 (Korat, E. Siam). 



Males with the rufous of the foreneck not extending so 

 far downwards as in other races and terminating abruptly 

 on the upper breast. Remaining lower parts a markedly 

 brighter, less greenish yellow. 



Females with lower parts brighter than in the typical 

 race (^. s. singalensis.
