37. Serinus leucopygius (Sundev.). 



I saw small parties o£ the White-rumped Grey Serin- 

 Fincli between Meslira and Chak Chak, but it was not nearly 

 so common in that district as the green-and-yellow S. icterus.

Numbers of this Finch Avere collected to roost in some 

 high trees behind Bringi's Village on the evening when I 

 arrived there. I shot two or three, but they were in full 

 moult, and I only kept one for identification. I did not 

 meet with the bird again.

These Weavers, in winter plumage, were abundant in 

 laro-e flocks at the Khor Gitti, Kuanga's, the Pongo and 

 Chell Rivers, &c., generally keeping to the vicinity of water. 

 Except for their chrome-yellow, instead of orange, shoulders 

 they looked very similar on the wing to the next species.

Abundant in the papyrus- and grass-swamps along the
