21790. The imperfect proximal extremitj- of the right tibia ; from 

 To Eangatapu. This specimen agrees in size with the 

 undermentioned tibio-tarsus, No. 18591, and should 

 therefore be regarded as referable to a male bird. 



Mantell Collection. 



The follotvi)uj specimens belong to the typical or presumed 

 male form (D. ingens). 



18591. Cast of the left tibio-tarsus. The original, which may be 

 taken as the type, and is also the type of D. ingens, was 

 obtained from Poverty Bay, and is preserved in the 

 lEuseum of the Royal College of Surgeons. It is men- 

 tioned by Owen in the ' Proc. Zool. Soc' 1843, pp. 8, 9, 

 as D. novce-zealandice, and figured in the ' Trans. Zool. Soc' 

 vol. iii. p]. XXV. figs. 1, 2, and pi. xxvi. figs. 1,2, and 

 also in the corresponding plates of the ' Extinct Uirds of 

 New Zealand,' as D. ingens. Its length is 0,730 (29 

 inches), and the width of the distal extremity 0.092 (3'6 

 inches). The proportions are precisely the same as in 

 the specimen No. 18588 : and the extensor bridge has a 

 similar shortness and obliquity.

 Royal College of Surgeons, 1844. 



28398. The left tarso-metatarsus ; apparently from the North Island. 

 This specimen, which agrees in relative size with the 

 tibio-tarsus, resembles the one from the North Island 

 figured by Owen in the ' Trans. Zool. Soc.' vol. iii. pi. xlviii. 

 fig. 1 (' Extinct Birds of Now Zealand,' pi. xl. fig. 1) as 

 D. ingens. Its length is 0,348 (13*7 inches); and its 

 proportions accord with those of the corresponding bone 

 of the female. Presented by — StoJces, Esq., 1853. 



32132*. The proximal phalangeal of the fourth digit of the left 

 pes, probably referable to a male iudi\'idual of this species ; 

 from the meuaccenite bed of Te Eangatapu. 



Walter Mantell Collection. 



18592. Cast of the right femur. The original, which was obtained 

 from Poverty Bay, is preserved in the Museum of the 

 lloyal CoUege of Surgeons. It is figured by Owen in the 

 ' Trans. Zool. Soc' vol. iii. pi. xxi. figs. 1, 2, and also in 

 the ' Extinct Birds of New Zealand,' pi. xxi. figs. 1, 2. 

 It would appear to indicate a smaller bird than the tarso- 

 metatarsus. Presented by the Council of the 



Royal College of Surgeons, 1844.
