PIEGAN SKULL FROM MONTANA (NO. 243673) 
(Plate xv) 
Skull of an aged male, without any sign of disease or deformation. The 
coronal, sagittal, and lambdoid sutures are, with most of the facial articulations, 
almost wholly occluded, but it does not appear that the shape of the skull on 
this account is in any way altered. 
The supraorbital ridges and the glabella are voluminous (particularly the left 
ridge) ; the former are restricted to a little more than the median half of the 
supraorbital space. Above the ridges and along nearly the whole bréadth of 
the frontal is a well-marked depression. The forehead is low and sloping, 
nevertheless it shows a distinct bend and small frontal eminences. There is a 
moderate, broad, median elevation of the region in front of the bregma and 
of a narrower ridge along the anterior fourth of the sagittal suture, giving 10 
the anterior and posterior planes of the skull a pentagonal appearance. The 
parietal bosses are quite prominent. 
The face is but slightly prognathic. The lower jaw is high; the chin promi- 
nent. 
There is no indication of an extraordinary musculature. 
The teeth are of average size. The denture shows the following anomalies: 
Congenital lack of all the third molars, and of the left lateral upper incisor ; 
submedian size of the right upper lateral incisor and an anomaly of the median 
tooth; and a small supernumerary tooth between the right upper canine and the 
first bicuspid.

C.—SKULL FROM MOUND NEAR BROWNING, SCHUYLER COUNTY, 
ILLINOIS (NO. 136778) 
(Plate xv1) 
This cranium shows the lowest natural forehead of any American skull with 
which the writer is acquainted. ; 
It is regrettable that the specimen is very imperfect; the whole face and 
everything below the parietals, with a small portion of the occipital, are lacking. 
Further, this skull is not absolutely normal, for the surface of the upper part 
of the frontal and of the parietals shows several irregular depressions, which 
may be senile, or due to some old weakness or lesions of the bones. These
