THE TURKEY HISTORIC 103 



In the skeleton of the manus, the pollex meta- 

 carpal projects forward and upward as a rather 

 conspicuous process. Its phalanx does not bear 

 a claw, and on the index metacarpal the indicial 

 process is present and overlaps the shaft of the 

 next metacarpal behind it. In the leg the fibula 

 is free, and extends halfway down the tibiotarsal 

 shaft. 



The hypotarsus of the tarso-metatarsus is 

 grooved mesially for the passage of tendons be- 

 hind, and is also once perforated near its middle 

 for the same purpose. As I have already stated, 

 the remainder of the skeleton of this bird is char- 

 acteristically gallinaceous and need not detain us 

 longer here. I would add, however, that the 

 "tarsal cartilages" in the turkey extensively 

 ossify.
