 almost identical, even inferiorly. The specimen shows no other 

 anomaly.

On the left side is present an anomalous 

 separation of the zygomatic process from the 

 body of the malar. (Fig. 5.) No trace of any 

 traumatism. On the right the zygomatic 

 arch has been lost. The specimen shows no 

 further anomaly.

size. mentioned was in any way pathological. 



In a number of Presbytes Semnopitheci, 

 one Hylobates, one Symphalangus, five Macaques, and one 

 Ateles, a more or less pronounced marginal cleft or fissure was 

 seen in the superior border (frontal process), three to five mm. 

 externally to the edge of the orbit, running to a foramen. 



There were found in the series no clearly defined anterior or 

 posterior partial malar sutures. 



The above six cases present a number of new points and will 

 be of value in the eventual summing up of the whole subject of 

 malar divisions. 



Several interesting cases of the anomaly in man and mam- 

 mals, including an orang, have also recently been reported by 

 Frassetto (Notes de Craniologie Comparee, Ann. Sc's. Natur., 

 Paris, Sept. 1903).
