HRDLICKA] SKELETAL REMAINS 79 
Above the foramen magnum, on the right side, the bone has been cut away 
to some extent with a sharp implement; on the left the occipital squama in 
this locality is so damaged that the original presence or absence of incised 
marks can not be determined. 
A portion of the ujjper face and a lower jaw are said to have been found 
with this skull, but on account of the defects they can not be fitted. They 
agree with the skull in color and both look quite fresh. They show the 
presence of alveolar prognathism of a medium grade, such as occurs in general 
in the Indian. The nasal aperture was apparently mesorhynic; its maximum 
breadth is 2.55 em. The nasal spine is now but of fair length; the borders 
of the nasal apertures are sharp. The submalar fossee were of good depth. 
The height of the upper alveolar process in the median line is very moderate, 
amounting to only 1.7 cm., without perceptible atrophy. The palate was well 
formed; maximum external breadth 64 cm. A_ bluish-black discoloration

is seen on the left side of the maxilla. The lower jaw @ has been recon- 
structed from several pieces, and unintentionally the separation of the rami 
has been increased. It is a normal specimen of moderate strength, and is a 
part of the same face to which belongs the above-described upper jaw; it 
shows a square chin and quite prominent and pronounced effects of muscular 
attachment on the external surface of the angles. The vertical rami with 
their processes and notch present nothing unusual. The teeth of both jaws 
are of moderate size; all are much worn off; only two molars exist on the 
left side in the upper jaw (right side broken), and on the right side in the 
lower one. The dentine and enamel of all the remaining teeth are in perfect 
condition, the latter preserving its normal luster. There is absolutely no feature 
of inferior development about these specimens. 
«The lower jaw depicted in Professor Ward’s paper, in Putnam’s Magazine for Jan- 
uary, 1907 (page 413), and marked “lower jaw of Nebraska skull no. 6,” is a specimen 
different from the one here described; it would seem that there must have been an 
error in assigning the Ward specimen to this skull.
