DINORNITHIDiE. 337 



32177 b. The last cervical vertebra of a still larger bird. The 

 spine is wanting, and the specimen otherwise imperfect. 



32177 c. A smaller imperfect last cervical vertebra. 



32177 d. Two perfect specimens of the penultimate cervical vertebra 

 of smaller birds. In the great forward inclination of the 

 neural spine these vertebra; present a great contrast, not 

 onh" to Dbiornis, but also to Anomcdopteryx parva. 



32177 e. A penultimate cervical vertebra, of which the spine differs 

 in contour from either of the preceding specimens. 



32177 f. Two last cervical vertebrae (one imperfect), agreeing in 

 size with the jn'eceding. The serial position of these 

 specimens is determined by the longer neural spine, in 

 which the posterior groove is much larger and descends 

 deeper between the prez}gapoph3-ses. They accord with 

 the specimen figured by Owen in his ' Extinct Birds of 

 New Zealand,' pp. 403, 404, figs. 18-20, as the fifteenth 

 cervical of Dinomis maximus, but which evidently belongs 

 to a species of the present genus. 



32177 g. The last cervical vertebra of a larger bird. The greater 

 part of the neural spine is wanting. 



32177 h. A similar specimen, with more of the spine remaining. 



32173 a-d. Four apparently associated posterior cervical vertebrae. 

 These specimens, which comprise the IGth, 17th, ISth, and 

 19th, are remarkable for their great width between the 

 zygapophyses, and the shallowness of the channel between 

 the postzygapophyses. 



32176 a. The last cerncal vertebra of a large individual. 



32176 b. A slightly smaller last cervical vertebra. 



32154 a. The first dorsal vertebra of a full-sized individual. The 

 extremely small size of the tubercular and capitular costal 

 articulations characteristic of this vertebra are shown. 

 The lateral borders of the anterior face of the centrum do 

 not project as far forward as the prezygapophyscs ; and 

 both faces of the centrum are much expanded. 



32154 a'. A nearly similar first dorsal vertebra, wanting the neural 

 spine and right transverse process. As in the preceding
