f. Phalanrieals. 

 The specinu.,^ Med under this heading may comprise some re- 

 ferahhto the other species. Unless the contrary is stated, they are 

 from liuamoa, and form part of the Walter Mantdl Collection. 



32117 a. The proxini^il phahui-eal of the second digit of the right 



aud left pes. These bones are much shorter than the 

 corresponding phalangeal of Dinomis, with the proximal 

 extremity more expanded and its articular surface flatter. 



32118 a. A smaUer example of the same segment of the left pes. 

 32184 a. The proximal phalangeal of the third digit of the left pes 



of a very large individual. This specimen accords in re- 

 ative size with the type tarso- metatarsus of P. immanis, 

 to which form it may have belonged. Although the ex- 

 tremities are larger than in the largest example of the 

 corresponding phalangeal of Dinornis maximus, x\o 3->151 

 (p. 2,ib), the whole length, as shown by the following 

 dimensions, is much less. The contour of the proximal 

 articular surface tends to a circular instead of a quad- 

 raugular form.

32116. Four smaller examples of the proximal phalangeal of the 

 third digit. 



47444**. A nearly similar specimen, belonging to the left pes • 

 from Otago. The proximal articular surface is less sym- 

 metrical than in Xo. 321S4 a. 



Presented by the Trustees of the Otarjo Museum, 1876. 

 32111 a. Two specimens of the proximal phalangeal of the fourth 

 digit of the left pes. These bones differ from the cor- 

 responding phalangeal of Dinornis by their extreme short- 

 ness, the greater expansion of the proximal extremity 

 and the prominence and great upward extension of the 

 distal trochlea on the anterior surface. 



32116 a. Two similar phalangeals of the opposite side.
