postarticiilar process distinctive of the genus ; the intervals 

 between the angles of opposite sides being scarcely less 

 than in the ranch larger mandible of Dinornis maximus 

 (fig. 55, A). The tracheal rings (' Trans. Zool. Soc' vol. x. 

 pi. li. figs. 10-12) arc very short and compressed, as in 

 A. didina. Purchased, 1880. 



Anomalopteryx oweni (HaastM. 



Syn. Diiioniis oweni, ITaast '. 



The smallest species. Allied to A. j^^iarva and A. cuHa ; being 

 smaller than the former, and distinguished from the male of the 

 latter by the more slender tarso-metatarsus, of which the length is 

 0,112 (4-4 inches), and the width at the middle of the shaft 0,020 

 (0-88 inch). The length of the tibio-tarsus is 0,223 (9-2 inches). 

 The proportions of the tarso-metatarsus approximate to those 

 obtaining in A. imrva ; and the skull referred to this species by 

 Haast is nearly as large as that of the latter, having the same 

 characters of the temporal fossa, but a wider beak. 



Hah. North Island. 



a. Limb-hones. 



A. 92. The left tibio-tarsus ; from Whangarei, North Island. The 

 length is 0,223 (9-2 inches), and the width of the distal 

 extremity 0,033 (1-3 inch). This specimen is indistin- 

 guishable from the type tibia from the same locality, 

 figured by Haast in the ' Trans. Zool. Soc' vol. xii. 

 pi. xxxi. fig. 12. 



Presented by Sir J. von Haast, K.O.M.G. 



A. 92 a. The left tarso-metatarsus, with the extremities imperfect ; 

 from Whangarei. Resembles the specimen figured by 

 Haast, op. cit. pi. xxxi. fig. 15 ; its length being 0,112 

 (4-4 inches). Presented hy Sir J. von Haast, K.G.M.G. 



A, 92 b. The right femur, with the extremities abraded ; from 

 Whangarei. Accords with the example figured by Haast, 

 op. cit. pi. xxxi. fig. 14. 



Presented hy Sir J. von Haast, K.O.M.O. 



32177. A rather small left femur ; from the North Island. The 

 length of this specimen is only 0,132 (5-2 inches).
