No. 424.] DIVISION OF THE MALAR BONE. 293 
In connection with the search for malar incisures in Indians 
two other points were noted, namely, the lineal, antero-posterior 
groove on the ventral surface of the malar (Gruber) and the 
temporo-maxillary arc. The groove was found to be almost 
constant, while the arc is generally more or less incomplete. 
NOTE. 
While my paper on malar divisions has been in the hands of 
the printer, the American Museum of Natural History has 
received two skulls of adult African lions, one of which shows a 
partial malar suture. 
The suture is in the left malar; the right malar has been 
fractured (post-mortem), and its posterior half is wanting. Dor- 
sally, the separation runs sagittally from a point slightly pos- 
terior to the angle of the 
temporal border of the 
malar and a somewhat 
greater distance anterior 
to the zygomatic suture, 
over more than half of 
the malar, after which it 
bends downward and ter- 
minates; the division is 
somewhat serrated and 
contains five small Wor- 
mian ossicles. Ventrally, the malar suture runs in a serrated 
manner a short distance forward and unites with the boundary 
of a large Wormian bone, the anterior extremity of which 
reaches to a point slightly posterior to the dorsal termination 
of the suture. 
The malar shows no signs of any recent or old injury, and the 
division is undoubtedly congenital. It is probably a remnant of 
a complete malar suture, the anterior extremity of which became 
subject to an early synostosis. The curving anterior end can 
be explained by a simultaneous excess in growth of the anterior 
portion of the superior, and the posterior portion of the inferior, 
part of the malar.
