"With the Gould Collection the Museum received the Singapore 

 specimen alluded to by Mr. Swinhoe (1. c). There can be little 

 doubt that it represents the winter plumage of the present species. 



The upper sui'face is ohve-brown ; the wings dusky brown, with 

 few remains of the light margins to the coverts and secondaries ; 

 the eyebrow is pure sulphur-yellow ; the lores and ear-coverts 

 blackish brown, washed with olive ; the under surface white, more 

 ashy on the breast, which has some yellow feathers intermingled, 

 doubtless the commencement of the summer plumage, as the throat 

 is already bright yellow. 



1 have seen in some coUcctious birds from the Moluccas marked 

 Mutacilla taivana ; but in ever}' case I believe the specimens to be 

 referable to true M. Jiava, traces of blue-grey being always dis- 

 cernible on the head. 



Hah. From the Kurile Islands, Eastern Siberia, Dauria, and 

 Amoor Land, throughout China and Formosa, wintering in the 

 Malayan peninsida.
