CRANIA FROM THE MOUNDS OF FLORIDA.

In marked contrast to the foregoing are the skulls which exhibit rounded fore- 

 heads and scarcely discernible frontal ridges. Together with this peculiarity the 

 face is inclined to chamseproscopy. Thus in an Assinaboine (fig. 4) the alveolar 

 height measures but 15 mm. The incisor eminence is small, but the ridge to the 

 nasal spine is marked, as is also the alveolar line. The hard palate is parabolic 

 and shallow. The foramen lacerum medium is almost closed, and the sphenoido- 

 tymppaiic fissure is not overlapped by the spinous process. 



In No. 1,815, Santa Barbara (fig. 5), a striking example is seen of a cymbe- 

 cephalic skull with convex forehead without prominent ridges, small narrow malar 

 bone and rudimental lachrymal bones. The nasals are sharply arched, the margins 

 of the anterior nasal aperture not expanded and the alveolus small.

Chamseproscopy is rare in North American Indians. For this reason three 

 examples are shown for comparison with the prevalent type of leptoproscopy as illus- 

 trated in the Moore series. Remarkable contrasts are seen between the Moore 

 series and all of the four crania, — No. 40, fig. 6, 418 Lenape, fig. 7, and 1,002 

 Otomie, figs. 8 and 9. Each of these specimens exhibits a depressed nasal bridge, 

 ascending process of the maxilla nearly at right angles with the inner wall of the 

 orbits, an expanded anterior nasal aperture, a rudimental alveolar line ; the spine, 

 incisor crest and eminence are small (analophic). The glabella and supra-orbital 

 ridges vary, being almost absent in No. 40, but prominent in Nos. 418 and 1,002.
