2 M. TACZANOWSKI ON BIRDS COLLECTED [Jan. 3, 



smallest known representative of its kind. The skull was larger in 

 proportion to the body than in Q\i\\ev Dinornis maximus or D. ingens, 

 but manifested no modification approaching to the shape of the bill 

 in Apteryx ; it retained the generic characters shown in all tlie 

 larger kinds of Dinornis. The sternum was strictly Dinornithic. 

 The chief osteological distinction was a greater number of cervical' 

 vertebrae ; but the author remarked tliat no other skeleton had 

 been discovered, or recovered from swamp-deposits, under circum- 

 stances precluding the oversight of two or more vertebra) from the 

 middle of the long neck, where missing ones might be indicated by 

 size or by joints. The metatarsus gave no indication of an articular 

 surfiice for a back toe, yet the bones of this minute digit of both feet 

 were transmitted ; hence the amalgamation of Paktpteryx with 

 Dinornis received additional support. The size of the bird was 

 about that of the Dodo. 



On the grounds detailed in the memoir the author referred its 

 subject to the genus Dinornis, and to a new species proposed to be 

 called D. parvus. 



In the remote, well-wooded, and sparsely populated district of the 

 southern division of New Zealand, Prof. Owen was of opinion that a 

 recovery of a still-existing specimen might be less unlikely than 

 that of the Notornis, also originally recognized by fossil remains. 



This memoir will be printed entire in the Society's ' Transactions.'
