 Known by the distal portion of the tibio-tarsus, which indicates 

 a bird of somewhat smaller size than the living G, virgo.

(Fig.) Eocene (Lower Oligocene) of Hordwell, Hampshire. The

structurallj' from the corresponding bone of G. virgo. 

 The long and deeply sunken bridge over the extensor 

 groove, as well as the transversely extended aperture of 

 the channel below the groove, are well seen. The contour 

 of the unfigured portion of the shaft is precisely the 

 same as in existing species. This specimen indicates a 

 far larger bird than the one on which Geranopsis is 

 founded. Hastings Collection. Pvrcliased, 1855. 



Grus princeps (Portis ^). 

 Sja. TalcBogrus pruiceps, Portis ^.

 writer cannot see how the distal extremity of the tibio-tarsus, by which it 

 is known, can be generically distinguished from Grus.
