Mr. R. B. Sharpens Catalogue of Accipitres. 3G9 



tervals between the transverse marks are slightly tinged with 

 pale brown wherever the immature plumage remains. 



The throat is a pure unbroken white^ as are also the under 

 tail-coverts, with the exception of a few indistinct traces of 

 dark transverse bars towards their lower extremity. 



The comparative length of the primaries in this species is 

 fourth, fifth, third, sixth, second, and first ; and the third, 

 fourth, and fifth primaries are rather conspicuously emargi- 

 nate on the outer as well as on the inner web. 



The following are the measurements of the two specimens 

 above described. 



Male. Female,

P.S. Since the above notes were written, a third specimen of this Hawk 

 has come to light, which also formed part of one of Mr. Anderssou's South- 

 African collections, but unfortunately without any record of the locality 

 where it was obtained. It was marked by Mr. Andersaon as a male ; but 

 I feel doubtful as to its really being so, its measurements, which are sub- 

 joined, being intermediate between those of the two examples previously 

 described. Jq

This specimen, which is about to be placed in the Norwich Museum, 

 agrees in its general plumage with the immature female described above,
