432 Savage and Wyman, External Characters, 
The heads of the two females, as will be seen by reference 
to the table of measurements, were both smaller than those of 
the males. A small occipital crest exists in both, but the in- 
ter-parietal is entirely wanting in one, and is represented by a 
very slight ridge in the other, though both, as is shown by the 
teeth being all protruded and more or less worn, have reached 
the adult period.. The crania are much more smooth, the out- 
lines less angular, and the general expression of the face far 
less savage and brutal than in the males. In the younger of 
the females the dentes sapientie were perfectly protruded, 
and some of their points slightly worn; in this head, as well 
as the others, the cranial sutures had become obliterated, but 
some of those of the face were still obvious, viz. the zygo- 
matic, the malar, and a portion of that between the maxillary 
and intermaxillary bones, and between the ossa palati. The 
inferior maxillary bone is smaller, and its ramus much more 
narrow than in the male, a condition corresponding with the 
less perfect development of the canine teeth. Two infra-or-

sixth, were remarkable for the great length of the spinous pro 
cesses, the longest of which, measured from the inside of ~ 
spinal canal (posterior face) had a length of 2.4 inches, the
