343 



by its great width. There is a foramen between the pre- 

 zygapophysis and the base of the transverse process, as in 

 No. 32161 d. 



32161 h. An entire dorsal vertebra, corresponding with the sixth 

 dorsal of Anomalopteryx parva. The neural spine is very 

 tall and thin ; and the posterior face of the centrum is 

 nearly square, and angulated, with two haemal processes 

 descending from its lower angles. 



32161 i. A rather smaller sixth dorsal, with one of the posterior 

 hfemal processes imperfect. 



32161 j. An imperfect sixth dorsal, of somewhat larger size than 

 No. 321617*. 



32164 a. A nearly similar specimen. 



32170 a. An imperfect posterior dorsal vertebra. The centrum is 

 relatively shorter than in the preceding specimens, but its 

 posterior face is more curved, and the transverse processes 

 are more nearly horizontal than in the undoubted seventh 

 dorsals. 



32161 k. A nearly similar but smaller specimen. 



32162 a. A vertebra (without the neural spine) corresponding to 



the seventh dorsal of Anomalopteryx parva. This vertebra 

 is easily recognized by the extreme flatness of the posterior 

 face of the centrum, the slight obliquity of the zygapo- 

 physes, and the width and upward direction of the trans- 

 verse processes. 



32162 b. A similar specimen, retaining part of the neural spine. 



32162 C. A smaller example of the homologous vertebra. 



Pachyornis immanis, Lydekker (n. sp.). 



A provisional species characterized by the tarso-metatarsus (fig. 66), 

 which attains larger dimensions than any of the specimens of that 

 bone referred to P. elephantopiis. The shaft of the tarso-metatarsus 

 is also relatively wider and more flattened than in that species, so 

 that the bone is the most massive type known in the family. The 

 dimensions of the type specimen are given below. 



The skull provisionally referred to this species is much more 

 depressed than that of P. elephantnpus, with deeper temporal fossae 

 and a shorter postorbital region. 



Hab. South Island.
