arched and elevated than is usual, and even than in the Curassow!. With this latter 
bird the Talegalla, however, agrees very closely in the structure of its whole pelvis, the 
bones being in both very spongy and thick. In the Talegalla the ‘‘ acetabulum ” is 
more in the middle than in Crax; and the prefemoral part of the ilium is longer, nar- 
rower, and steeper: the os pubis is also thicker. Moreover the ‘‘ossa innominata”’ 
are wholly coalesced with the sacrum in Craz, only in the anterior half in Gallus, whilst 
they are wholly separate in Talegalla. Also in Talegalla and Crax the curious pre- 
acetabular spur is much shorter than in the type. In the Apteryz the bones are still 
more reptilian than in the Talegalla: in the former the cervical vertebre are much the 
strongest ; and the ribs and pelvic bones are coarse and flat, while in the Talegalla 
they are coarse and thick, 
Remarks on the Viscera of Talegalla lathami. 
The digestive organs of Talegalla are extremely capacious; the crop is very large, 
and shaped like a simple mammalian stomach, such as that of Man or the Bat. The 
proventriculus is long; the gizzard strong, as in Gallus ; the duodenal fold very long, 
and the intestines and ceca both long and very capacious. The whole length from 
the pharynx to the end of the cloaca is 68} inches, the length from the pharynx to 
the gizzard being 12 inches.

* The arching of this part is just similar to what is seen so markedly in Brachypteryx, Psophia, aud Rhino- 
chetus ; and in other respects the pelvis approaches to what we see in those genera.
