rib, behind which cup is a large pneumatic foramen. The ribs of the seven succeeding 
sacrals are anchylosed and short, abutting against and coalescing with the closely 
grasping plates of the antacetabular parts of the ilia. The interpleural vacuities of 
the eight anterior sacrals rapidly decrease in size to the fifth, and again slightly expand 
in the last two. ‘The first three pairs of anchylosed ribs incline forward; the next three 
pairs are transverse; the last of this series curves slightly backward, commencing that 
curve which is carried out by the proximal ends of the ischia. Both ischia and pubes 
in the present specimen are broken away from their origins at the acetabulum. The 
following are the dimensions of this pelvis :—

It may be convenient for future comparers of the hind-limb bones of Dinornis to 
have, in a tabular form, the principal dimensions of the femur, tibia, and metatarsus of 
the several species at present defined and named. In this table are given references to 
the figures of the type specimens affording the dimensions; and there are added remarks 
and dimensions by Dr. Haast, F.R.S., the latter of bones obtained from the swamp of 
Glenmark, and which are referable to the above species of Dinornis.
