of New Zealand,' p. 412, fig. 31, as the sixth dorsal of 

 Dinornis maximus. The characteristic shallowness and 

 width of the valley between the postzygapophyses are well 

 shown. 



32165 a. A smaller fifth dorsal, in which the neural spine is more 

 upright. 



32161 a. A nearly similar specimen, wanting the neural spine. 



32160 f. A still smaller fifth dorsal, with the neural spine imperfect. 

 In this specimen vertical buttresses rise from the upper 

 surface of the postzygapophyses and transverse processes 

 to join the neural spine. The centrum narrows inferiorly 

 on its posterior face. 



32160 g. An entire fifth dorsal. This specimen, although resembling 



the preceding in size, agrees with No. 32171 b in the 

 contour of the posterior face of the centrum. 



32161 b. An imperfect fifth dorsal vertebra. The posterior face of 



the centrum is shorter and wider than in the preceding 

 specimen. Neural buttresses are present. 



32160 h. A fifth dorsal vertebra, wanting the neural spine. The 



posterior face of the centrum is squared, and buttresses 

 are present. 



32168 a. An entire fifth dorsal resembling the preceding. 



32161 c. A slightly larger fifth dorsal, with a similar contour of 



the centrum. The transverse processes are larger than 

 in the last specimen, and there are no buttresses. 



32161 d. A similar specimen, wanting the neural spine. 



32161 e. A very large fifth dorsal vertebra, wanting the neural 

 spine. This specimen has no neural buttresses, and in 

 the contour of the posterior face of the centrum resembles 

 No. 32161 a. The vertical diameter of that face is 0,050, 

 and the transverse 0,048. The specimen may be referable 

 to P. imTnanis. 



32161 f. The centrum and base of the right side of the arch of a 

 vertebra agreeing in size with the last, and probably being 

 the sixth dorsal of the same bird. 



32161 g. An imperfect smaller fifth dorsal vertebra. The posterior 

 face of the centrum differs from the preceding specimen
