In making the measurements in the case of the pelvis of 
the female in this table I was careful not to take into con- 
sideration the caudal vertebree which we found united with 
the sacrum in this specimen. 
Of the Sternum and Shoulder Girdle : So well known is 
the general form of the sternum among typical Galline, 
and in Gallus in particular, that it would be more than 
superfluous labor for me to enter upon a detailed descrip- 
tion of the bone in the present connection. My figures 
faithfully portray its form in the adult male G. bankiva 
(Figs. 8 and 9), and Darwin has told us that in the case of 
domestic species he found out of twenty-five sternums 
examined by him, that ‘‘three alone were perfectly sym- 
metrical, ten were moderately crooked, and twelve were 
deformed to an extreme degree.”* Its a well known fact 
that it is a rare thing to come across a perfectly symmetrical 
sternum from a common domestic fowl, whereas it is truly 
an elegantly fashioned bone, not only in bankiva, but in 
many of its allies as the Grouse and Partridges.t Much of 
this is due to the graceful sweep of its deep keel, its lofty 
costal processes, its wide-spreading and delicate xiphoidal 
limbs; and its handsome manubrium, transversely pierced 
at its base by a communicating foramen connecting the

his ‘Contrib. to the Anat. of Birds,” p. 714, Figs. 81 and 82, and p. 704, Fig.
