It is plain that while among the whites the medium form of the notch
very largely predominates, among the Munsee this form is absent, though
this is doubtless accidental to some extent at least, owing to the
relatively small number of specimens. The complete foramen is much more
frequent in the Munsee than in the whites.
As to the sexes, in both the Munsee and the whites there is observable
a predominance of the deeper forms and the complete foramen among the
males, and of the shallower forms and the complete absence of the notch
in the females.
As to sides, no characteristic differences in the notch appear.
