The .specimens mentioned on pages 240, 241 appear to indicate a 

 transition from the female of D. novre-zealand Ice to D. maximits, and 

 it is therefore probable that the latter should be regarded as a 

 modification of the former which has attained larger dimensions and 

 relatively more slender limbs. Haast ', after having been disposed 

 to refer some of the specimens from the South Island to D. nova- 

 zealandice (gif/anfeiis), ends bj- regarding them as inseparable from 

 D. maximiis. 



Hah. South Island. 



The following specimens, ivMch include casts of the types, 

 are recjarded as referable to female individucds. 



A. 161. Casts of the associated left femur, left tibio-tarsus, and 

 right tarso-metatarsus. The originals, which are the 

 types, were obtained from Glen mark Swamp, about 45 

 miles from Christchurch, Canterbury, South Island ; and 

 at the time of their description were in the possession of 

 Major J. Michael, of the Madras Staff Corps. They are 

 figured on a small scale (with a restoration of the foot) by 

 Owen in his ' Palteontology,' 2ud ed. p. 330, fig. Ill, as 

 I), rjiganteus ; they are likewise described and figured by 

 the same writer in the ' Trans. Zool. Soc' vol. vi. pp. 498- 

 500, pis, Ixxxix., xc, and in his ' Extinct Birds of New 

 Zealand,' pp. 251-253, pis. ixxix., Ixxx. In the figures 

 the tarso-metatarsus is represented as being of the left 

 side. The length of the tibio-tarsus is 0,990 (39 inches), 

 and the diameter of its distal extremity 0,126 (b inches) ; 

 the length of the tarso-metatarsus being 0,506 (20 inches). 

 The extensor bridge of the tibio-tarsus is somewhat 

 oblique. Made in the Museum. 



A. 161 a. Model of the left tarso-metatarsus. This specimen was 

 modelled from the right tarso-metatarsus of the preceding 

 series, and is mounted in the case with the tibio-tarsus 

 and femur. Made in the Museum. 



A. 162. Casts of an associated right femur, right tibio-tarsus, and 

 left tarso-metatarsus, probably referable to a smaller 

 female. The originals, which at the time of their de- 

 scription were in the pcssession of the Duke of Argyll, 

 were obtained from Glenmark Swamp. They are noticed 

 by Owen in the 'Trans. Zool. Soc' vol. vi. p. 497, and- 

 also in his ' Extinct Birds of 'New Zealand,' p. 250. The 



' Ibis, ser. 3, vol. iv. p. 214 (1874).
