1 and 3 breed together in the central parts of Burma and in 

 the north of the Malay Peninsula, and 1, 3 and 4 are found 

 together on various parts of Burma, Siam, Yunnan, etc., in 

 the same areas. 



The following key may suffice to define the species. 



J\e!/ to Species. 



A. Chin and throat yellow. 



a. Abdomen entirely grey, or with a mere trace 

 of yellow. Tail long, 3.3-37 mm., and black 

 suffused with green Z. jntlpchrosa. 



h. Abdomen with yellow central streak. Tail 



short, 30-32 mm., practically blaclc . Z. aurcicenter. 



c. Abdomen yellow all over Z. siamensis. 



B. Chin and throat dark greenish yellow Z. ceylonensis. 



Z. palpehrosa extends througliout India and Ceylon, i\\Q 

 greater part of Burma^ the north of the Malay Peninsula, 

 Siam, Yunnan, and practically throughout southern China. 



Z. reijlonensis is confined to Ceylon. 



Z. aureiventer extends from Java, Sumatra, Borneo, 

 through the Malay Peninsula, E. Pegu, Karennee to the 

 Kachin Hills. 



Z. siamensis is found in central and southern Burma, 

 Siam, and Cocliin-China. 



The form of Z. jxdpehrosa found in the hills south of the 

 Brahmaputra is very close to Z. anreirenter, but has the 

 long, greenish tail of the former and must be retained in 

 that species. 



I recognize the following species and subspecies within, 

 or adjacent to, the Indian area.

The type is a dark bird with wing of 54 mm. and bill of

 did Chota Nagpore, and it is evident the bird came from one
