sagittal region is but very slightly elevated. The bregma-lamlxla 

 arc measures 11.8 cm. (33.8 per cent of the arc from nasion to 

 opisthion). There is only one parietal foramen (right), of moderate 

 size. Temporal ridges were not high in position and are barely per- 

 ceptible. 



The occipital region is quite full, not protruding; the right side is 

 very little more prominent than the left. Occipital ridges and 

 depressions are very faint. The temporal regions show moderate 

 bulging. The squamro are low. The zygoma? are quite slender. 

 Pterions are of II form, rather narrow. 



The sutures show as yet no traces of ossification. Their serration 

 is superior to that in any of the Lenape skulls. A distinct serration 

 is seen in the posterior third of the temporo-parietal sutures, a condi- 

 tion which is uncommon. There are no Wormian bones. 



The base of the skull is rather flat. The foramen magnum is 

 quite large, measuring 3.8 cm.' in its antero-posterior and about 2.9 

 cm. in its maximum lateral diameter. The plane of the opening, if 

 extended forward, would pass only about 1 cm. beneath the nasion. 

 The processes are low, the foramina of moderate size except the fo- 

 ramina ovale, which are smaller than the average in female crania. 

 The styloids are broken ; they were, particularly the left, very slen- 

 der. The glenoid fossae are of fair depth, the right being slightly 

 more spacious than the left. 



The ventral surface of the skull shows but few and shallow impres- 

 sions of the convolutions; it is scaling off similarly to the outer sur- 

 face. Thickness of the left parietal 3 to 4 mm. 



The differences between this specimen and the various Lenape and 

 eastern crania, as shown by the inspection, are even more plainly 

 indicated by the principal measurements and indices (see tables, 

 page 41). The most characteristic features of the specimen are its 

 considerable breadth coupled with extreme narrowness of the face; its 

 extremely small height, which is noticeable even if we compare the 

 auriculo-bregmatic instead of the basi-bregmatic heights, and which 

 gives rise to very low height-length and height-breadth indices, and 

 the megaseme character of its orbits. Differences of such nature and 

 so great in number are entirely beyond the scope of individual varia- 

 tion. When found in a normal skull, as this is, they can represent 

 only racial characters. In this case they effectually differentiate 

 the Burlington County cranium from all those crania recognized as 

 Indian. 



The Riverview Cemetery cranium (no. 44280, Peabody Museum) 

 is that of a male about fifty years of age. It is somewhat damaged, 

 but enough of the face as well as of the vault is preserved for almost 

 all of the more important measurements. (Plate iv.) The skull
