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

Fatco trprauis. Shaw. 
Le Faucon a culotte noire, Le Vaillant, Ois d’ Afrig. pl. 29. 
F. griseo-fuscus ; gula alba; corpore subtus rufescente striis 
longitudinalibus nigro-brunneis, 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, and 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 Sneewwbergen, in the District of Graaff-Reinet. 
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.
