HRDLICKA] PHYSICAL ANTHROPOLOGY OF THE LENAPE 51 
The face is of moderate dimensions and lacks prognathism. The 
facial index ranges from mild chamaeprosopy to mild leptoprosopy. 
The orbits are very variable, but the majority are mesoseme. 
The nose is rather short, but fairly broad; the average index is 
mesorhiniec. 
The palate is of only moderate length, but fairly broad; its index 
in both sexes is brachyuranic. 
The lower jaw is of moderate dimensions throughout. 
The teeth are medium in size. 
Descriptive features.—The forehead is chiefly of medium develop- 
ment in the males, in the females frequently somewhat low. 
The sagittal region shows more or less arching, in no case extreme; 
the temporo-parietal region and the occiput present mostly medium 
forms. 
Serration of cranial sutures is submedium to very submedium. 
Wormian and other intercalated bones are scarce. The order of 
occlusion of sutures among the males was S—C-TO-L; among the 
females TO-S-C-L (see page 35). 
The pterions are all of the H type, with tendency to narrow in 
males, medium to broad in females. 
Parietal foramina are few in number and small, retromastoid fora- 
mina moderate to small. 
The mastoid processes and the supraorbital ridges present ordi- 
nary development and variation; no excess. 
The nasion depression is well marked in the males, mostly shallow 
in the females; nasal bridge is medium to submedium, nasal bones 
of fair breadth; lower borders of the nasal aperture are mostly 
fairly sharp, and with one exception there are no simian grooves or 
subnasal fosse; nasal spine ranges from very low to submedium. 
The orbits show exceptional variation in form, as they do in meas- 
urements; suborbital (canine) fosse are shallow to medium; malar 
bones are of but moderate development, without anomalies; zygomex 
average somewhat submedium as compared with those of other 
Indians. 
The upper alveolar arch is mostly of very moderate slant and free 
from abnormalities. The lower jaw is of ordinary form, without 
anomalies. The palate in half the cases is elliptic, in two-thirds of 
the remainder ovoid, and in one-third parabolic; it is in no case 
exceptionally low or very high, and there is no torus. 
Base.—The glenoid fosse in a majority of the crania show usual 
form and medium dimensions, but tend to wideness in a number of 
the females; dehiscences in the floor of the auditory meatus are, 
for Indians, scarce. 
The styloid processes reach medium development in but few 
instances, and they are frequently rudimentary.
