The features of chief interest with respect to the nasal aperture are
the fullness or sharpness of the inferior borders, the presence or
absence of subnasal fossæ or simian gutters, and pronounced asymmetry.
Among the 19 Munsee skulls in which these features can be studied,
there are only one instance of moderate grooves and three cases of
moderate asymmetry. The lower borders are fairly sharp, more so than
the average in many other Indians.
