of Dinormtlikla;aX VVaingongoro, North Island. Figured 

 by Owen in the ' Trans. Zool. Hoc' vol. iii. \A. xxxiii. 

 figs. 11-13, without specific determination. The specimen 

 agrees in every respect with the corresponding portion 

 of the cranium of a recent example. Purchased, 1848. 



21699. A similar spcciuicu ; from the same locality. 



Parchased, 1848. 



A. 117. The imperfect naso-prcmaxillary region of a rather larger 

 cranium ; found in association with the bones of Dinorni- 

 thidce, locality unknown. This specimen is stained exter- 

 nally to a chocolate colour, as is so commonly the case 

 with remains of Dinornithidce ; it presents no characters 

 by which it can be specifically distinguished from the 

 existing form. Wcdter- Mantel! Collection. 



Purchased, about 1855. 



Genus CONURUS, Kuhl '. 



The skull is very like that of Ara, although much smaller, having 

 a similar deep and deflected premaxillary region, small nares, and 

 a complete bony orbital ring. The edges of the premaxillae are 

 notched. 



In Chri/sotis the narial apertures of the skull are much larger. 



Conurus, sp. 



The undermentioned specimen agrees in size with C. er>/throgeni/s, 

 of Guiana, and probably belongs to one of the species now inhabiting 

 Brazil. 



JIab. South America (Brazil). 



40673. The anterior portion of the cranium ; from the Pleistocene 

 of Buenos Ayres, Argentina. This specimen shows the 

 entire naso-premaxillary region, the anterior extremity of 

 the frontal region, and the imperfect palatines, which have 

 been bent down at right angles to the beak. The mineral 

 condition resembles that of many Mammalian fossils from 

 the same deposits, Bravard Collection. Purchased, 1854.
