21493 b. The imperfect distal extremity of the left tarso-mctatarsus 

 of an Accipitrine bird of larger size than Buteo vulgaris ; 

 from the Lower Miocene (Upper Oligocene) of Weissenau, 

 near Mayence. This specimen, in which the outer trochlea 

 is wanting, does not accord with any of the species described 

 by Milne-Edwards from Allier. Purcliased, 1847. 



21493 c. Tlic imperfect proximal extremity of a left metacarpus, 

 probably associated with the preceding ; from Weissenau. 



Pxircliaml, 1847. 



Genus PALiEOCIRCUS, Milne-Edwards \ 

 Founded upon the metacarpus, which is considered to present 

 affinities both to Aqnila and Fandion, and also to show some resem- 

 blances to the Buzzards. The undermentioned phalangeals resemble 

 those of the former genus in the shortness of their proximal process 



Palseocircus cuvieri, Milne-Edwards '\ 



The type and only described species. Somewhat smaller than 

 Aqriila clirysaetus. 



Hah. Europe (France and [?] England). 



25165*. The imperfect terminal phalangeal of the first or second digit 

 of the pes, not improbably referable to this species ; from the 

 Upper Eocene (Lower Oligocene) of Hordwell, Hampshire. 

 This specimen, of which the proximal portion is wanting, 

 is almost indistinguishable from the somewhat larger cor- 

 responding bone of Aqui J a cJirysae{us. The type specimen 

 is from the same horizon in the Paris basin.

25165**. The terminal phalangeal of the third or fourth digit of 

 the pes, probably belonging to the same species as the 

 preceding; from Hordwell. Although resembling the 

 corresponding phalangeal of Aquila in the shortness of the 

 proximal posterior process, this specimen- presents differ- 

 ences which are evidently of generic value.
