HuTTON. — On the Moa-bones from Enfield. 647 



connecting-links with M. casuarinus, have well-marked con- 

 centration foci of their own, showing clearly that it is distinct 

 from that species. Compared with the same species from 

 Kapua, the metatarsus and the femur are the same, but the 

 tibia is distinctly larger. There can be no hesitation in 

 accepting this result, as the data are ample. 



In my former paper, already referred to, I placed a few 

 bones doubtfully under the name of P. 2^l/9''^^^us. These, 

 however, do not belong to Pachyornis, but lie on the border- 

 land betv,-een M. didimts and E. gravis. On the wdiole, I 

 have concluded that they are a variety of the former, and I 

 have included them here. They consist of — metatarsi, 5 ; 

 tibiae, 4 ; femora, 4. Possibly they are hybrids between the 

 two species. 



Euryapteryx crassa. 



Metatarsi, 58 ; tibiae, 17 ; femora, 68. This species was, 

 comparatively, less numerous than at Kapua. The tibia is 

 larger, but the metatarsus and femur are the same. 



Euryapteryx ponderosa. 



Metatarsi, 16 ; tibiae, 14 ; femora, 28. These numbers 

 are too small to give any results of value, but the bird 

 appears to have been rather smaller and more slender than 

 at Kapua. 



Euryapteryx gravis. 



Metatarsi, 20; tibiae, 12; femora, 10, So far as these 



numbers allow us to form an opinion, it would seem that 



the tibia is considerably larger, while the femur is slightly 

 smaller. 



Pachyornis inimanis. 



Metatarsi, 7 ; tibiae, 4 ; femora, 7. The numbers are small. 

 The tibiae are all of large size, and none of them shows the 

 curvature of the shaft which is so remarkable in the bones 

 from Kapua and Hamilton. Two of the femora are larger 

 than any found at Kapua. The average is larger because no 

 small bones were found. 



Pachyornis elephantopus. 



Metatarsi, 21 ; tibiae, 17 ; femora, 15. There is in this 

 species a most remarkable development in length without the 

 great thickness characteristic of P. immanis. The metatarsi 

 reach a length of 267mm. ; the tibiae, 622mm. ; and the femora, 

 368mm., which are considerably greater than the largest from 

 Kapua. The average, however, is smaller.
