pression. The mastoid cells of the temporal bone were largely 
developed, and were continuous with other cells of similar size 
situated in front of the auditory meatus; large cells also ex- 
isted at the inner extremity of the petrous bone. 
As in S. satyrus, the foramen magnum of the base of the 
skull is elongated, and has an emargination on its posterior 
edge, and the anterior condyloid foramen is double in one ot 
the males, though in the other crania the second or venous 
canal is very minute compared with that which transmits the 
hypoglossal nerve. (XIth pair.) A well developed ridge on 
the temporal bone, (corresponding with the “ vaginal process” 
of the human anatomist) extends from the carotid foramen to 
the auditory meatus, but there is no obvious surface for the 
attachment of a styloid process. A stout cylindrical process a 
obliquely terminated, the extremity somewhat roughened as if 
for a muscular attachment, is situated just behind and beneath 
(the head being in its natural position) the orifice of the 
Eustachian tube. 
x "The lower, jet presens a degree of massiveness and strength 
ination of the great surface for the attachment of the tem- 
poral muscles, and the great size of the zygomatic arches. 
In its general conformation it resembles that of the Simia 
satyrus, but surpasses it in size, although the projection of the 
face in the last is the greatest. Its ascending portion is nearly ver- 
tical, and contrary to that of the Chimpanzée and Oring; 
the coronoid process is more elevated than the condy: loid.” -
