 in the present paper, 



Falco communis, Gm. ; Sharpe, Cat. B. Brit. Mus. i. 

 p. 376. 



No. 19. An immature bird. 



Falco concolor, Temm. ; Sharpe, t. c. p. 405. 



No. 12. Quite a young bird, the determination of which 

 has given me some trouble. The peculiar pink hue of the 

 under surface is quite different from that of any young 

 Hobby with which I am acquainted, and no specimen out of 

 our large series of Falco subbuteo can be found to match it. 

 I therefore believe it to be an immature Falco concolor, 

 although it does not resemble exactly any specimen I have 

 yet seen, nor any figure of the young bird. This, I fancy, 

 may be due to the fact that the Muscat specimen is younger 

 than any previously procured by naturalists. I have asked 

 Colonel Miles to endeavour to obtain an adult bird of this 

 Falcon, and shall await its arrival with interest. 



The only specimen of this species from North-eastern 

 Africa in the Museum is an adult bird from Efat in Shoa, 

 obtained by Sir W. C. Harris, It is very much lighter grey 

 than any of the Madagascar specimens in the collection, but 

 much resembles the figure given by Grandidier and Milne- 

 Edwards (Hist, Nat. de Madagascar). This species would 

 appear to be subject to melanisai, as all the Madagascar 

 specimens in the Museum are blacker than the Efat bird.
