 The undermentioned vertehrce, ivlnch indicate large birds, are rela- 

 tively much longer than those of Pachyornis elephantopus. They 

 u'ould apj^ear to he too large for Emeus crassus, apart from the 

 circumstance that in the mounted skeleton of E. gravipes the ver- 

 tehrce resemble those of Pachyornis in their relative shortness. The 

 cervicals of the present series are less elongated than those of 

 Dinomis, and have not the deep channel between the ^wstzygapo- 

 physes found in the latter. The dorsal is of the general type of 

 Pachyoruis. All the S2)ecime7is were obtained from Euamoa, and 

 belong to the Walter Mantell Collection, purchased about 1855. 



32163 X. Three early middle cervical vertebra. These apparently 

 represent the 7th, 8th, and 9th, and seem to be asso- 

 ciated, 



32163 y. A later (? 10th) cervical vertebra. This specimen could 

 not have belonged to the same individual as the preceding. 



32147 X. A later (? 11th) cervical vertebra, according in characters 

 with the preceding specimen. 



32163 z. A middle cervical vertebra (? 12) apparently associated 

 with No. 32163 x. 



32149 X, A late middle cervical vertebra. 



32150 X. A late middle cervical vertebra. 



32174 X. Two associated posterior cervical vertobrte. 

 32167 X. A posterior cervical vertebra. 



32177 X. Two posterior cervical vertebrae. 



32175 X, The sixth dorsal vertebra. This specimen presents a re- 



markable contrast to the corresponding vertebra of Pachy- 

 ornis elephantopus, the neural platform having its longer 

 diameter running antero-posteriorly instead of trans- 

 versely. The position of the anterior pneumatic foramen 

 is the same as in Pachyornis, and therefore different from 

 Dinomis.
