It is probable that a large proportion of the undermentioned specimens 

 are referable to the preceding and folloiving species, although 

 it is almost certain that some belong to the larger species of 

 Anomalopterjx. It may be assumed that most of the smaller 

 and stouter specimens belong to E. gravipes, tJiese bones being 

 relatively shorter and stouter, ivith a more flattened anterior 

 surface of the shaft, than is the case in Anomalopteryx. TJie 

 larger and more slender femora,which generally exceed in sizethose 

 referred to Anomalopteryx casuarina, are probably in great part 

 referable to E. crassus, ivith the more slender tarso-metatarsus of 

 which they accord. It will, however, be understood that it is in 

 many cases quite impossible to distinguish between the femora of 

 the larger species of Anomalopteryx and those of the present 

 genus ; so that cdl references are provisional. 



33144:, 1. A small riglit femur; from Waingongoro, North Island. 

 Walter Mantell Collection. Purchased, about 1855. 



19467, 1. A nearly similar left femur ; from the South Island. 



Earl Collection. Purchased, 1845 



47444, 18. A slightly larger right femur ; from Otago. This 

 specimen comes very close to the corresponding bone of 

 the skeleton of E. gravipes, No. A. 95 (p. 299), having 

 the same sharp angulation at the junction of the external 

 anterior trochlear ridge with the shaft — a feature common 

 to many of the specimens included under the present 

 heading.

47444, 19. A still larger right femur ; from Otago. 



Presented by the Trustees of the Otago Museum, 1876. 



41268. A larger and stouter right femur ; from the South Island. 

 Although this specimen agrees in relative size and mineral 

 condition with the tibio-tarsus of Pachyornis, No. 41266 

 (p. 319), yet the relative length of the shaft, as weU as 

 the form and relations of the head and great trochanter, 

 are essentially those of Emeus. It approximates to the 

 femur figured in Owen's ' Extinct Birds of New Zealand,' 

 pi. xli. A, as Dinornis gravis. Purchased, 1867.
