206 REPORT ON. AN ADDITIONAL COLLECTION OF SKELETAL 
the distal end of the jugular process and the condyle, in the region of the insertion 
of the rectus capitis lateralis muscle, is frequently met with in Indian crania, and 
those of the series under discussion form no exception. On the other hand, a large 
cylindrical and articular process, while by no means unknown in the Indians, is of 
rare occurrence. Regarding the present series, two of the male and one of the 
female skulls from Louisiana show moderate non-articular pa 'amastolds, while one 
cranium (female No. 259.103) has on the right side an articular process 0.9 em. 
high and of equal diameter.! 
The posterior condylotd foramina are less often absent or diminutive in the 
Indian skulls from Arkansas and Louisiana than in those of whites. There are in all 
28 skulls in which these structures can be examined, and of these they are normal

in 25, or 82 percent. Of the remaining 5 skulls, one of the canals is wholly occluded 
in two and partly occluded in three. The obliteration occurs in male as well as in 
female skulls; it is present twice on the right side and three times on the left. 
The jugular foramen is found, as in whites, to be more frequently larger on 
the right side, as will be seen by the following table :?

the condition of the para-mastoids is as follows: Moderate non-articular elevation on each side; M. 0, F. 2.
