No. 424.] DIVISION OF THE MALAR BONE. 281 
This case differs from any thus far on record, The exact 
nature of the division is uncertain. 
Case 7, Unilateral Malar Division in a Bear. (No. 4282, 
American Museum of Natural History ; Fig. 9). — The division 
affects the left malar of a young American black bear (incisors 
and canines not yet replaced by teeth of the second dentition). 
Dorsally only the superior third of the division is open, the 
other portion of it being secluded but still traceable ; ventrally 
the anomalous suture is patent in its entirety. 
The division begins anteriorly considerably below the middle 
of the malo-maxillary articulation and runs in almost a straight

direction upward and slightly backward, to the base of the 
frontal process. The suture shows a slight serration. 
The frontal process of both the malars is partly detached. 
The right malar shows a small anterior incisure in a location 
corresponding to the antero-inferior terminus of the division 
on the left. Finally, there are on the left one small bone and 
two larger, oblong ones, and on the right one large, oblong 
osside, intercalated between the antero-inferior two-thirds of 
the malar and the superior maxilla. 
The two malars show but little difference in size. 
The above specimen is one of twenty young adolescent and 
young adult skulls of bears of the same variety preserved in 
the American Museum of Natural History. No other of these 
skulls presents a complete malar division similar to that in 
No. 4282; several of the specimens, however, show an anterior 
malar incisure, visible on the internal surface of the bone. 
Besides this almost all the specimens present more or less of a 
separation of the frontal process of the malar. In four of the

etc. (1873), p- 195, Pl. V, Fig. 1). See also Bresc
