In conclusion, I may mention two adult Falcons froip 

 Nepal, which were presented by Mr. Hodgson to the British 

 Museum, and which, notwithstanding the very eastern locality 

 where they were obtained, I can only refer to Falco punicus. 

 The smaller of these specimens, which I believe to be a male, 

 is entered at p. 387 of the Museum Catalogue under the 

 head of Falco barbarus, and the larger, which is presumably 

 a female, is one of the two specimens entered at p. 389 under 

 the title of Falco babylonicus, to which species the other speci- 

 men from Nepal, also thus entered, does appear to me really 

 to belong. The following are my measurements of these 

 Falcons : —

 By F. W. Styan, F.Z.S. 



(Plate VI.) 



In 1885 I purchased in Hankow two living specimens of a 

 Trochalopteron which appears to be undescribed, and for 

 which 1 propose the name of T. cinereiceps. Its nearest ally is 

 T. cineracenm of Godwin- Austen (P. Z. S, 1874, p. 45, pi. xi.).
