wings) being broad and shewing in strong contrast to their 
blackish centres. On the other hand, the example a is 
singularly dark, slightly speckled on the breast, and with 
the margins of the feathers of the back and wings brown 
and dark russet-brown, instead of whitish-buff and pale 
olive-brown. Indeed this last bird differs so markedly from 
the others that it is difficult to believe that it belongs to the 
same species. There are, however, several dark specimens 
in the National Collection that agree perfectly with my 
Manchurian skin, but these (known to the older authors 
under the name of L. ruhescens Blyth) were mostly procured 
in winter. Perhaps they are all young birds ; but if 
immaturity is the explanation of this dark phase, it is some¬ 
what curious to find it in an example killed as late as 
June 8th, and in an individual that must necessarily have 
passed through both the autumn and spring moults. 
Crossing from Japan to Vladivostock in June 1907, a 
Grasshopper-Warbler came on board our steamer. It was 
in such an exhausted condition that it allowed me to 
approach within two or three feet of it, so close, in fact, 
that I made several attempts to catch it in my hands. I 
am confident that it belonged to the present species, which 
is the more interesting as this Warbler was hitherto un¬ 
recorded from Japan.
