12 Observations Upon the Morphology of 
jaw.”* And, indeed, I fully believe this to hold true with 
specimens of the wild Gallus bankiva; and so well known 
now are these several structures that it will be but neces- 
sary to touch upon them lightly in the present connection, 
the less imperative is it, too, as I have taken no little pains 
in my illustrative exhibition of them in Fig. 4 of this 
article. One thing it will be well to record, however, and 
we are to note that each and every one of these parts are 
conspicuous for their slenderness as compared with the 
corresponding structures as we find them in the skulls of 
most common chickens of barn-yard breeding, wherein such 
bones as the quadrates, pterygoids and palatines seem to be 
more heavily fashioned. Gallus bankiva has an extremely 
delicate pair of mazxzllo-palatines, performed in osseous 
tissue, and separated by quite an interval in the middle 
space. 
Hither palatine is noted for the slender ‘‘ maxillary pro- 
cess” which it sends forward to its usual articulation with 
the bony structures beneath the superior osseous mandible; 
and those processes are well separated mesially, as are the 
inner margins of the internal lamina of the palatines 
along the nether surface of the rostrum of the sphenoid 
(Fig. 4). 
Posteriorly, the ‘‘ pterygoidal process” of a palatine,turns 
outwards and articulates in a socket, designed for its 
reception, in the head of a corresponding pterygoid. As 
in all true gallinaceous species this jungle fowl has the 
posterior external angles of the palatines most completely 
rounded away. 
A vomer, of the most delicate construction possible, is 
found to be freely supported upon the tips of the forward 
projecting ‘‘ ascending processes” of the palatines, where 
they nearly meet beneath the apex of the sphenoidal 
rostrum. This diminutive vomer is forked behind, and as 
sharp as a needle in front; and I find it better developed 
in the skull of the male than I do in the skull of the
