There is a pelvis in the WeHington Museum, from Wai- 

 pawa, which has the length of the ilium 470mm., length of 

 pre-acetabular portion 223mm., and breadth at the anti- 

 trochanters 203mm. In Mr. A. Hamilton's collection, from 

 Te Ante, there is a much smaller pelvis, in which these 

 measurements are 305mni., l-lOmm., and 152mm. respec- 

 tively. In the Canterbury Museum there is an imperfect 

 cranium and pre-maxilla, from Wanganui, which is 60mm. 

 wide at the temporal fossae, while the distance between the 

 temporal ridges is 44mm. The pre-maxilla belonging to this 

 skull is 78mm. in length; the length of the body is 46mm., 

 and its width 47mm. 



D. struthioides is smaller and more slender than D. torosus, 

 and the extremities of the leg-bones are not so dilated. It 

 has been found from Whaiagarei in the north to Wanganui 

 in the south. 



Megalapteryx tenuipes. 

 Megalapteryx tenuipes, Lydekker, Cat. Fossil Birds in Brit. 



Mus., p. 251 (1891). Megalapteryx tenuijjes, Hutton, 



Trans. N.Z. Inst., vol. xxviii., p. 635 (1896). 



There are in the British Museum two femora from the 

 North Island which Mr. Lydekker refers to this or an 

 allied species. One has a length of 255mm., while the other 

 is slightly smaller and relatively narrower, especially at the 

 distal extremity. The latter comes from Waingongoro, near 

 Wanganui. 



There are no bones of Megalapteryx from the North Island 

 in the Canterbury Museum, and I have not seen any in any 

 ■other museum.

Figures. — (?) Tibia, Trans. Zool. Soc, iii. (and E.B.), pis. 

 "25, 26, figs. 3, 4 {didiformis) ; femur, I.e., iv., pi. 41 (E.B., pi. 

 54), fig. 1. 



The type of this species is a femur from Opito, near Mer- 

 cury Bay, which has a length of 278mm., a proximal width of 

 95mm., a mid. width of 38mm., and a distal width of 101mm. 

 There is in the Canterbury Museum a femur, from Akitio, 

 which closely resembles the type, but is smaller. With it I 

 provisionally associate a tibia and metatarsus (Plate XLVII. , 



* Substituted for Aiiovialopteryx, as that name is preoccupied (1874) 

 in the Neuroptera.
