Mr. E. Hargitt on the Genus Chrysophlegma. 261 
by Mr. Sharpe, to whom ornithologists will for ever be 
indebted. The Hume Collection possesses a large series of 
all the Indian species, including adult males and females and 
the young, carefully sexed and dated, and from almost every 
locality which the species is known to inhabit. With the 
advantages of having such a complete series placed before one 
for inspection, difficulties which were at first most perplexing 
became more easy of solution, and a knowledge of the 
changes of plumage more readily acquired, so that I am 
now enabled to place before the readers of f The Ibis J many 
notes which appear to me to be interesting, and which I 
could not have supplied had it not been for this recent addi¬ 
tion to our National Museum. I am also under many obliga¬ 
tions to Hr. Jentink and Heer Biittikofer, of the Leiden 
Museum; and also to Hr. Oustalet, of the Paris Museum, 
who has given me much valuable information concerning the 
species of the present genus contained in the collection under 
his superintendence.
