A. 158. Cast of the distal portion of the right tibio-tarsus. The 

 original was obtained from the Pleistocene cavern-deposits 

 of the Wellington Valley, New South Wales, and is pre- 

 served in the Museum at Sydney. It agrees very closely 

 with the corresponding bone of the above-mentioned 

 species, the dimensions of the two bones being as 

 follows : —

Genus HYPSELORNIS, Lydekker (gen. nov.). 

 Founded upon the second phalangeal of the third digit of the pes, 

 which differs from that of Casuarius ' in the following points : — Its 

 stouter form ; the mbre triangular shape and deeper excavation of 

 the proximal articular surface, in which there is no distinct median 

 ridge and the posterior border is nearly straight ; the abrupt rise of 

 the proximal portion of the anterior surface, which gives a concave 

 instead of a nearly straight profile ; the deeper and wider anterior 

 supratrochlear depression; and the deeper intertrochlear notch.

39733. The second phalangeal of the third digit of the right pes ; 



{Fig.) from the Pliocene of the Siwalik Hills. The type ; de- 

 scribed and figured by Davies in the ' Geol. Mag.' decad. ii. 

 vol. vii. p. 22, pi. ii. figs. 2, 2 «, 2 6; and also by the 

 present writer in the ' Palaeontologia Indica ' (^lem. Geol. 

 Surv. Ind.), ser. 10, vol. iii. p. 146, pi. xiv. fig. 8. The 

 corresponding bone of Casuarius emeu figured by Davies 

 for comparison in the plate cited belongs to the left, or 

 opposite side. The contour of the upper border of the 

 trochlear surface on the anterior aspect is not correctly 

 indicated in either of the figures of the fossil.
