622 ZOOLOGY SECT, xiv 



The Pleistocene passes insensibly into the Recent period, which 

 has also witnessed some important zoological changes, especially 

 the extinction of many interesting animal forms, for the most part 

 by human agency. Among these may be particularly noticed 

 Steller's Sea-cow (Rhytina), the Great Auk, the Dodo and Solitaire, 

 several flightless Rails (Aptornis, Notornis, Aphanapteryx, &c.), 

 the Phillip Island Parrot, and, above all, the whole great race of 

 Moas.
