In none of the specimens at hand can be detected any premature
occlusion, though in this respect it is impossible to be certain as
to the temporo-occipital articulations. Unfortunately, there is no
possibility of giving the exact relation of age to the occlusion in
any of the sutures; all that it is possible to determine is their
relative involvement. The order among the males is S-C-TO-L;[43] that
in the females, TO-S-C-L. It is plain that occlusions in the coronal
and temporo-occipital sutures are almost as early and frequent as
those in the sagittal, while those in the lambdoid are decidedly
later. As to locality, the coronal suture occludes first below the
temporal ridges; in the sagittal the commencement is most frequent,
as usual, about obelion; in the lambdoid it is irregular; while in
the temporo-occipitals in the Munsee it advances generally from the
anterior or basal extremity of these sutures backward and upward.

lambdoid.
