 Plentiful. On the way northwards. 



[It is very interesting to see that some of Mr. Jackson's 

 specimens are in full moult in March, and that some of 

 them retain a considerable amount of yellow on the under 

 surface, while others are decidedly greyer below. Some of 

 the latter look like ChifEchaffs as regards their plumage ; 

 but I believe the whole series to belong to P. trochiJus, 

 though the moulting quills in some of them make it difficult 

 to identify them with absolute certainty. — R. B. S.]
