31397. The proximal extremity of the left ulna. 

 31404. Tlie distal half of the right ulna. 



31401. The distal part of the right ulna. 



31402. The distal portion of the right ulna. 



31595. A slightly imperfect left femur, wanting the distal extre- 

 mity. It closely resembles the femur figured by :^Iilne- 

 Edwards, op. cit. pi. Ixx. figs. 9, 10. The upper part of 

 the deep anterior trochlear groove is well shown, but 

 owing to the loss of the lower extremity, the character- 

 istic form of the condyles is not exhibited. The proximal 

 extremity agrees with the same part in existing species. 



24955*. The right tarso-metatarsus, wanting the inner trochlea. 

 Resembles the type specimen figured by Milne-Edwards, 

 o£>. cit. pi. Ixx. figs. 2, 3 ; its length being 0,070. The 

 whole contour is very similar to that of the corresponding 

 bone of /. hncjirostris ; the latter being, however, abnormal 

 in having a tube in the talon for the passage of the tendons.

31704. The proximal portion of a left tarso-metatarsus, not impro- 



bably belonging to this species. 



31705. The imperfect distal extremity of a right tarso-metatarsus, 



provisionally referred to the present species.

48188 g. The proximal extremity of the left humerus ; from the 

 Middle Miocene of Lierheim, near Hahneuberg. So far 

 as can be determined, this specimen presents aU the cha- 

 racters of the humerus of lUs, showing the triangular 

 section of the proximal portion of the shaft, the strong 

 ridge on the dorsal aspect of the same, the isolated posi! 

 tion of the surface for the insertion of the pectoralis minor, 

 and the large subtrochanteric fossa (filled with matrix in' 

 the specimen). The delto-pectoral crest is somewhat
