On the Remains of an extinct gigantic Bird. 321 



Q, from Mogador, had nearly, but not entirely, assumed the 

 adult dress when it died ; except for its much larger size, it 

 is hardly distinguishable from F. barbarus, as the rufous on 

 the nape is similar in extent and disposition to the nuchal 

 collar of that species, but is not quite so bright and is rather 

 more intermingled with slaty black ; most of the feathers on 

 the crop have somewhat indistinct dark shaft-marks : the 

 breast and abdomen are spotted as in T ; but the spots are a 

 little larger. 



I have not had a recent opportunity of examining X, from 

 Tangier ; but I have a note, made some time since, to the 

 effect that it much resembles specimen R. 



Before leaving the subject of F. peregrinus and its allies, it 

 will be right that I should mention the two Sardinian Falcons 

 for which Mr. Sharpe, in the ' Annals and Magazine of 

 Natural History ' for January 1873, proposed the specific 

 name of Z>roo,^ei (subsequently withdrawn in his 'Catalogue'); 

 but as I have not recently examined these specimens, which 

 are preserved in the British Museum, I defer my remarks 

 upon them till my next paper, hoping, in the interim, to be 

 able to visit the Museum and to see them there.

XXII. — On the Remains of an extinct gigantic Bird supposed 

 to be allied to Cariama, from the Ossiferous Caves of 

 Brazil*. By J. Reinhardt. 

 It has long been known that the caves in the limestone 

 mountains of Brazil contain bones of other vertebrate classes 

 besides the very numerous mammalian remains which are 

 buried in them. The former certainly are but few in number 

 as compared with the latter ; but bones of birds more parti- 

 cularly are found in some caves in no small quantity; and 

 though a part of them may be of doubtful antiquity, others 

 possess those characteristics which are found in those bones 

 which are usually described as fossil. 



As yet, however, but very little has been made known con-
