No. lM5y3 (p. 268), provisionally referred to A. dro- 

 mceoides, from which it cannot be specifically distinguished, 

 thus suggesting that the present form is not entitled to 

 specific distinctness. Walter Mantell Collection. 



41272. An immature left tibio-tarsus ; from the South Island. The 

 extremity of the cuemial crest is still imperfectly joined 

 to the rest of the bone, and the extensor bridge does not 

 appear to have been ossified. Purchased, 18G9. 



19468 b. A larger immature left tibio-tarsus, probably referable to 

 this species ; from the South Island. Earl Collection. 



41264. The left tibio-tarsus of a still younger bird, probably refer- 

 able to the present form ; from the South Island. The 

 upper part of the cnemial crest has been separated and 

 lost, and the astragalus is only partially anchylosed to the 

 shaft. Purchased, 1869. 



b. The Tarso-metatarsus, 



At least a considerable proportion of the following specimens may he 

 pretty safely referred to this form; some of the smaller ones, 

 however, probably belong to A. dromaeoides and A. didiformis, 

 luhile in the case of some of the stouter large specimens, it is not 

 always possible to say that they should not he referred to Emeus 

 gravipes or E. crassus. 



32048 a. A large right tarso-metatarsus ; from "Waikouaitu. This 

 {Fig.) specimen (fig. 58, C, p. 230) agrees fairly well with the 

 tibio-tarsus No. 32045, from the same locality. Its length 

 is 0,213 (84 inches), and the width at the middle of the 

 shaft 0,038 (1'5 inch). It is slightly larger than the 

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

 pi. xlviii. fig. 3 (' Extinct Birds of New Zealand,' pi. xl. 

 fig. 3). Walter Ifantell Collection. 



32048 b. A rather shorter and relatively stouter left tarso-metatarsus; 

 from "Waikouaitu. Wcdter Mantell Collection. 



32048 C. A left tarso-metatarsus provisionally referred to this 

 species ; from "Waikouaitu. This specimen has the same 

 length as the tarso-metatarsus of Emeus crassus, iv o . 

 47444/ (p. 309), but is more slender.

41263. A nearly similar left tarso-metatarsus specifically identical 

 with tlie ju'cccding ; from the South Island. This speci-
