318 Mr. J. H.GviYney's Notes on 



otherwise he consirlerccl as indicating advanced age, which I 

 helieve that it nsually docs. The rufons on the nape of A and 

 I rancli resembles that on F; in other respects A and 

 I come nearest to N. 



Both in A and in I the dark cross bars on the undersurface 

 are strongly marked, but in the centre of the breast are 

 replaced by conspicuous black spots, this being more parti- 

 cularly the case in I. 



C, from Tangier, resembles I, but has distinct black 

 shaft-marks on the feathers of the crop. 



G, from Anascha, Mount Taurus, much resembles F, but 

 has rather more rufous on the nape, and the cross-barring on 

 the thighs and lower abdomen is more distinct ; the grey of 

 the lower scapulars is also rather paler. 



H, from Gozna, Mount Taurus, is similar to G, but is 

 darker on the interscapular feathers, and the rufous which is 

 mingled with the slaty black on the sides of the nape is 

 brighter and somewhat more extended ; many feathers of the 

 crop show small black shaft-marks, none of which appear on 

 that part of the plumage in G. 



In ' The Ibis ' for 1859, p. 187, Mr. Salvin recorded the 

 capture of two breeding specimens of " Falco barbarus " in 

 the Eastern Atlas — one at Djebel Dekma, which he marked 

 as a male, the other at Kef Boudjato, which he marked as a 

 female, the latter being the bird figured in the plate of F. bar- 

 barus which accompanied Mr. Salvin^s paper above referred 

 to. In this article Mr. Salvin, speaking of these two speci- 

 mens, both of which he very liberally presented to the Norwich 

 Museum, suggests that he was probably mistaken as to the sex 

 of one of them, as that marked male is rather larger than that 

 which is marked female*. My belief is that the sex of both 

 birds was correctly determined, and that the fact of the male 

 being a little the larger is due to the circumstance that the 

 female bird only (i. e. the specimen obtained at Kef Boudjato) 

 really belongs to F. barbarus, and that the male from Djebel 



* My wiug-measurements of both these birds are slightly in excess of 

 those given by Mr, Salvin, probably fi'om some little diftereuce in the mode 

 of measurins'.
