the humerus. The tibio-tarsus has a wide tubercle above the iuter- 

 coudykir gorge on the outer side of the extensor bridge (fig. 21, B) ; 

 and the anterior channel occupies the greater portion of the length 

 of the shaft. The tarso-metatarsus has the talon forming two 

 ridges separated from one another by a wide open channel, and a 

 deep groove on the anterior face. 



In the humerus the surface for the origin of the brachialis anticus 

 is long and oval.

Apparently very closely allied to the existing P. rosms, the re- 

 mains that are at present known scarcely indicating any disiinctive 

 specific differences. As in the existing species, there appear to 

 have been considerable individual variations in size.

27698 X. Mass of sandstone showing the proximal extremity and 

 portions of the shaft of the right humerus ; from the 

 Lower Miocene (Upper Oligocene) of Chaptuzat, near Cler- 

 mont-Ferrand (Puy-de-D6me). Indistinguishable from 

 the humerus of P. roseus.

27830*. Fragment of rock showing the proximal portion of a 

 somewhat smaller right hiimerus ; from the Lower Mio- 

 cene of Puy-de-D6me. The delto-pectoral crest has been 

 crushed out of its normal position. Croizet Collection. 



27617. Fragment of rock with the distal portion of a left humerus 

 agreeing in size with the preceding specimen ; from 

 Chaptuzat. Croizet Collection. 



27685. Slab of rock showing the distal part of the left radius and 

 ulna, the carpal bone, and the proximal portion of the 

 metacarpus ; from the Lower Miocene of Perignat, near 

 Clermont-Ferrand. The shafts of the long bones are 

 broken. Croizet Collection. 



31495 X. The left metacarpus, with the thinner bar imperfect ; 

 from the Lower Miocene of St. Gerand-le-Puy (Allier). 

 Ilesembles the corresponding bone of the preceding speci- 

 men, and is slightly larger than the metacarjnis figured 

 by Milne-Edwards in his ' Oiseaux Fossiles de la France,'
