crauiura as indioativo of tlie close affinity between A. casu- 

 arina and A. lUdiformis. The present specimen, which 

 was not improbably associated with the sternum Xo. 42502, 

 comprises the calvarium, the two quadrates, the premaxillae, 

 and the imperfect mandible. It is of considerably smaller 

 size than the skull of the skeleton No. A. 129, of A. di'li- 

 fonnif. The quadrate (Owen, op. cit. fig. 13) exhibits the 

 sharp anterior process distinctive of the genus. 



Presented by W. Beeves, Esq., 1870 



32214, 32199. The imperfect skull: from the South Island. 



(Pii/.) Described and figured by Owen in the 'Trans. Zool. Soc' 

 vol. Tii. p. 135, pi. xii. figs. 1-5 and S-10, and also in the 

 ' Extinct Birds of New Zealand,' p. 271, pi. Ixxv. figs. 1-5 

 and 8-10, as Dinornis rJieides, all the figures being reversed. 

 This specimen, which is soqiewhat larger than the pre- 

 ceding, comprises the calvarium, both quadrates, the left 

 quadrato-jugal, the maudiblo, and two rings of the trachea. 

 It does not apjiear certain that all the bones are asso- 

 ciated. Wcdter Mantell Colleedoii. 



32204. The calvarium and right quadrate of a rather larger bird ; * 

 {Flij.) from the tSouth Island. Described and figured by Owen 

 in the ' Trans. Zool. Soc' vol. vii. pi. xi. figs. 1-4, and also 

 in his 'Extinct Birds of New Zealand,' p. 266, pi. Ixxvi. 

 figs. 1-4, as Dinornis crassits. The calvarium is figured 

 in conjunction with the premaxilte of Emeus, No. A. 189 

 (p. 312). That the calvarium does not belong to Emeus 

 is at once shown, not only by the prominent supraoccipital 

 tuberosity and the contour of the basioccipital, but also 

 by the forward inclination of the cavity for the head of 

 the quadrate (compare the skull of Emeus, No. 32188, 

 p. 311), and the shortness of the anterior process of the 

 quadrate itself. Wcdier Mantell Collection. 



32219. A nearly similar calvarium, imperfect anteriorly, and a frag- 

 ment of the mandibular symphysis ; from the South 

 Island. Walter Mantell Collection. 



32199. A similar calvarium ; from the South Island.
