DixoRNiTinD.5;. 249 



the tj-pes. It is described aud figured by Owen in 

 the ' Trans. Zool. Soc.' vol. iv. p. 144, pi. xlii. fig. 1, and 

 referred to the present species ; the figure being reversed. 

 It is likewise figured in the ' Extinct Eirds of New Zea- 

 land," pi. Iv. fig. 2, but is not the specimen mentioned on 

 pp. 21 G, 217 of that volume as so figured, but the one 

 referred to on p. 219, which is incorrectly said to be the 

 one figured as D. struthioides. The length of this specimen 

 is 0,595 (23-5 inches), and the width of the distal extremity 

 0,071 (2-8 inches). It accords in relative size with the 

 preceding specimen, and from their similarity in minera- 

 logical condition it is highly probable that both may have 

 belonged to a single individual. Like the following tibio- 

 tarsus, the present specimen is too narrow at the distal 

 extremity to accord with the type tarso-metatarsus of 

 D. struthioides. Presented by Sir R. Owen, K.C.B., 1857. 



32147. A slightly smaller right tibio-tarsus, with the extremities 

 {Fig.) imperfect ; from Waingongoro, North Island. This speci- 

 men (fig. 54, B, p. 219) accords in relative proportions with 

 the preceding.

32502. A series of twenty more or less imperfect vertebrae probably 

 referable to this species ; locality unknown. These speci- 

 mens are relatively longer and more slender than the 

 cervicals of D. struthioides. In nearly all of them there 

 is a pneumatic foramen in the lamina of the arch, but in 

 one of the most anterior ones this is present only on one 

 side, showing its slight importance. The contrast pre- 

 sented by the great elongation of the earlier cervicals to 

 those of the skeleton of Anomalopteryx imrva is very 

 striking. No history. 



Genus MEGALAPTERYX, Haast '. 



Distinguished from Dinornis by the extreme slenderness and 

 length of the femur and tibio-tarsus, aud the relatively shorter 

 tarso-metatarsus, of which the length is considerably less than that 

 of the femur.
