CARINAT.E. 



Genus IBIDOPODIA, Milne-Edwards >. 



Founded upon the evidence of the tarso-metatai'sus. which is 

 more deeply grooved than in Ibis, with a smaller proximal intcr- 

 cotylar tuberosity, a shallower facet for the hallux, and the abortion 

 of the crests of the talon, which has no distinct channels for 

 tendons ". 



The skull provisionally referred to this genus differs considerably 

 from that of Ibis, having a comparatively short, wide, and straight 

 beak, approximating more to the type of the Ciconiidce. 



Ibidopodia palustris, Milne-Edwards ^. 



The type tarso-metatarsus is about two-thirds the length of that 

 of Ibis longirostris, but the skull referred to the species is nearly as 

 large as that of the latter.

26847*. The imperfect hinder portion of a cranium resembling the 

 one figured by Milne-Edwards in his ' Oiseaux Fossiles 

 de la France,' lA. Ixi. figs. 13-15, nnder the present name ; 

 from the Lower Miocene (Upper Oligocene) of AUier. The 

 prominent vertical ridge on the supraoccipital and the 

 vaulting of the brain-case, by which this type of skull 

 diii'ers from that of Ibis, are well shown.

Genus IBIDOPSIS, Lydekker (n. gen.). 

 The distal extremity of the tibio-tarsus is narrower than is 

 usually the case in Ibis *, and the proximal cnemial crest is less 

 deep. The cranial rostrum provisionally referred to the genus is 

 narrower and less deflected than in Ibis.

36793. The distal portion of the right tibio-tarsus ; from the Upper 



{Fig.) Eocene (Lower OHgocene) of Hordwell, Hampshire. This, 



the type, specimen (fig. 20) has almost precisely the same

 ^ A similar talon occurs in the Tinamidce. ^ Loc. cit. 



•* The distal condyles of the tibio-tai"3us are much more widely separated in 

 I. longirostris than in /. rubra.
