The chief characteristic of the collection is the great num- 

 ber of bones of Meionornis didinus, one-third of the whole 

 belonging to that species. 



Dinornis maximus. 



Metatarsi, 11 ; tibiae, 7 ; femora, 5 ; may be referred to 

 this species. The largest metatarsus was 19-5in. in length, 

 with a width of 2-5in. at the middle of the shaft; but there 

 was no tibia nor femur to match it. Indeed, the femora ap- 

 pear to be smaller than those from Kapua, but the number is 

 too few to base any well-founded opinion on. 



Dinornis rohustus. 



Metatarsi, 4 ; tibiae, 3 ; femora, 3. These bones are too 

 few to base any conclusions on ; but it does not appear to have 

 been clearly marked off from the last species. 



Dinornis torosns. 



Metatarsi, 19 ; tibiae, 7 ; femora, 15. This species is very 

 distinct from the last — more so even than at Kapua. The 

 number of bones is not large ; but they show a concentration 

 round a single focus with each bone, and no separation into 

 two sizes which might belong to the two sexes. This is a 

 satisfactory corroboration of the result arrived at by an exami- 

 nation of the Kapua bones, and ought to set the question of 

 the different sizes of tlie sexes in Dinornis at rest for ever. 



Meionornis casuarinus . 



Metatarsi, 74 ; tibiae, 64 ; femora, 78. The same difficulty 

 exists as at Kapua in separating the leg-bones of this species 

 from those of E. crassa. The metatarsus is the same size as 

 at Kapua, but the tibia and femur are rather larger. The 

 numbers are, I think, quite sufficient to establish this point 

 satisfactorily. 



Meionornis didinus. 



Metatarsi, 119; tibiae, 136 ; femora, 122. The tibia is very 

 well separated, and the other two bones, although showing
