A skull of OdontojL>teri/x toiiai^ka (Owen), from the Loudon Clay, 

 with powerful serrated mandibles serving in place of teeth, merits 

 attention. 



The fine series of flightless birds is also specially deserving of 

 notice, comprising, as it does, two species of Gastornis, one from 

 Croydon, Surrey, and one from Paris * ; the skuU of an Ostrich-like 

 bird from the London Clay of Sheppey {Dasornis londiniemis) ; 

 bones and eggs of ^pyornis from Madagascar ; remains of an 

 Indian Ostrich from the Siwalik Hills ; of Dromornis from Australia ; 

 and some twenty-two species of Binornithidce represented by a 

 grand series of skeletons, detached bones, and eggs of the " Moa," 

 from New Zealand, including most of the specimens figured and 

 described by Sir Richard Owen. 



A small series of bones of the Dodo from Mauritius, with a 

 skeleton of the Great Auk from Funk Island, indicate the principal 

 objects of interest embraced in the present Catalogue. 



Although the great majority of entries of Bird-remains are 

 referable to existing genera, yet it will be seen that there is a 

 considerable number of remarkable extinct forms, and figured 

 types, to impart to this portion of the Collection a high scientific 

 value.
