Gallus Bankiva of India. 23 
sacrals in the sacrum of its pelvis. Even this is at variance 
with Huxley’s count, for these segments in the sacrum of 
a young chick of the common barn-yard species, where he 
makes but five urosacrals.* Nor do I believe we can be 
safely guided in this matter by the ‘‘ double foramina” for 
the exit of the spinal nerves, for in the pelvis of the male 
bird before me, the first of these is found just anterior to 
the transverse process of the last dorso-lumbar, and count- 
ing this pair of foramina as number one, we find it followed 
by ezght other similar ‘‘double foramina” as we proceed 
towards the urosacrals. Professor Parker’s drawing seems 
to me to miss it just in the other direction, for he gives us 
in the sacrum of a ‘‘young fowl” but four sacrals and 
seven urosacrals ; this, however, is much better as it makes 
the total count correct ;+ and in doing so sets Darwin’s 
figures aright. 
Jungle Cocks, as will be seen from Fig. 15, have the 
supero-posterior angle of the pygostyle drawn out into a 
long, spine-like process, and this seems to be approached 
by other gallinaceous species, as, for example, the Centro- 
cercus of the Western plains of the United States. 
Excepting the atlas, axis, ribs, and caudal vertebrae, I 
find that the parts of the axial skeleton which we have 
been. considering in the present section to be quite thor- 
oughly pneumatic, perhaps some portions of the pelvis 
being less so than any, while many of the vertebre are 
highly so. 
Before proceeding to the consideration of the shoulder- 
girdle and sternum, I will add here a few comparative 
measurements of the pelves of the male and female G. 
bankiva, employing as above the metric scale.
