Mr. E. Hargitt on the Genus Chiysophlegma. 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 youngj 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 ' The Ibis ' 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 Dr. Jentink and Heer Biittikofer, of the Leiden 

 Museum; and also to Dr. 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.
