Island. The ossification of the distal extrcmitj- is incom- 

 plete, so that the popliteal depression is not closed in- 

 feriorly. The extreme shortness of the necic and slight 

 projection of the head indicate that the specimen belongs 

 to Dinornis. Walter Mantell Collection. 



19458. An imperfect pelvis and sacrum ; from the northern part 

 of the South Island, The greater part of the left ilium is 

 wanting, and the pubes and ischia are imperfect ; the 

 hinder portion of the sacrum is also missing. Tlie charac- 

 teristic flattening of the ventral surface of the sacral 

 vertebriB, and also of the postacetabular portion of the 

 ilium, is -svell shown. Earl Collection. Purchased, 1845. 



32040. The left acetabular region of the pelvis of a larger bird; 

 from Waikouaitu, on the east coast of the South Island. 

 From its large size this specimen probably belongs to 

 D.maximvs; it may at once be distinguished from the 

 pelvis of Pachijornis by the form and position of the 

 muscular rugosities immediately in advance of the ace- 

 tabulum. Walter Mantell Collection. 



21760. An imperfect anterior dorsal vertebra : from the menaccenite 

 bed of Te Eangatapu, near Waingongoro, North Island. 

 The generic position of this specimen is indicated by the 

 extreme shortness of the neural spine, and the great 

 width and depth of the space between the postzygapo- 

 physes. The specimen is smaller than the dorsals of 

 D. maxinms, and larger than those of B. strutJiioides.

Syn. Dinornis (Palapteryx) struthioides, Owen ''. 

 Dinornis novce-zealandice, Owen^ (inpai-te). 



A species of comparatively small size, founded upon the tarso- 

 metatarsus, which has the same general proportions as in D. maxi- 

 mus, its length being typically 0,304 (12 inches). The shaft of 

 this bone (fig. 58, B) is narrower than in the spccifiicaUy unde- 

 termined form mentioned on page 239. The tibio-tarsus has a 

 length of 0,545 (21-5 inches) to 0,583 (23 inches). 



Some of the specifically undetermined specimens mentioned on 

 p. 241 suggest a transition from this species to D. maximris. 



Bab. Typically the North, but also ranging into the South Island.
