(32-5 inclies), and the transverse diameter of its distal 

 extremity 0,111 (4-4 inches). The width of the distal 

 extremity is therefore greater than in the larger bono 

 (No. 18590, p. 225), which is one of the types of the so- 

 called D. giganteus; its proportion to the length being 

 rather more than one-seventh, instead of more than one- 

 eighth. The extensor bridge is long and but slightly 

 oblique. The right tibio- tarsus is figured in woodcut 

 '54, A, and the tarso-metatarsus in 58, A.

32043. The left tibio-tarsus ; from Waikouaitu. This specimen is 

 indistinguishable from the corresponding bone of the pre- 

 ceding specimen. Walter Mantell Collection. 



32043 a. A slightly larger right tibio-tarsus, with the proximal 

 extremity imperfect ; from Waikouaitu.

19452. The right tibio-tarsus, with the extremities somewhat im- 

 perfect ; from the South Island. The proximal extremity 

 agrees precisely with that of the specimen from the same 

 collection figured by Owen in the ' Trans. Zool. Soc' 

 vol. iii. pi. xlv. i]g. 1 (' Extinct Birds of New Zealand,' 

 pi. xxxvii. fig. 1) as D. <jiganteus (plate lettered D. gigas) ; 

 thus clearly shewing that this type of hone did not belong 

 to the so-called D. ingens, var. rohustus. This specimen 

 agrees in size with No. 32043. 



Earl Collection. Purchased, 1845. 



The imperfect skull, in several fragrneuts ; from the northern 

 part of the South Island. Figured by Owen iu the 

 ' Trans. Zool. Soc' vol. vii. pi. xiii. figs. 9-12, and also in 

 the ' Extinct Birds of New Zealand,' pi. Ixxviii. figs. 9-13, 

 as D. giganteus. The fragments comprise the imperfect 

 cranial box, which has been vertically bisected, the left 

 quadrate, the imperfect premaxillse, and the greater part 

 of the mandible, in an imperfect condition. The specimen 

 is somewhat smaller than the skull of No. 46631, with 

 which it agrees closely in characters : the fragment of the 

 mandibular symphysis which now remains showing the 

 same strongly-marked inferior ridges.

 (Fig.) vertebroe, with the imperfect pelvis and sacrum, belonging 



36640.
