 rocks, or on trees upon the banks of rivers, and lays four 

 eggs of a whitish red color. 



FALCO TIBIALIS. Shaw. 



Le Faucon a culotte noire, Le Vaillant, Ois d'Afriq. pi. 29. 



F. griseo-fuscus ; gula alba, ; corpore subtus rufescente striis 

 longitudinalibus nigro-bnmneis, femoribus fasciis longitudina- 

 libus nigris. 



Male. Bill yellow at base, horn colored elsewhere ; cere 

 yellow ; eyes bright hazel ; head blackish brown ; interscapu- 

 lars and shoulders grayish brown, with a deeper colored 

 streak along the middle of each feather ; throat white ; breast, 

 belly, arid under tail coverts reddish white, with brown 

 blotches, which are smaller behind than before ; thighs 

 blackish brown, with the feathers edged and tipt with 

 whitish. Primary wing feathers and tail also blackish brown, 

 with whitish edgings and tips ; tarsi feathered to within a 

 little distance of the toes ; bare part yellow, as are also the 

 toes ; claws black ; wings, when folded, considerably shorter 

 than tail. Size between that of the Accipiter Musicus and 

 the last described species. 



Le Vaillant killed a male, of which the foregoing is the 

 description, while feeding upon a young hare, which it had 

 just killed on the mountains of Great Namaqualand ; and he 

 says he was informed that the same species was very common 

 on the Sneeuwbergen, in the District of G-raaff-Eeinet. 



Obs. Though the shortness of the wings, and the partially 

 feathered tarsi, might appear to establish this as a separate 

 species from the last, yet there are many circumstances which 

 suggest the identity of the two, and that the present is the 

 description of a young bird. As I have neither met with the 

 one nor the other, the descriptions given are copied nearly 

 verbatim from Le Vaillant.
