No. 449-] MALAR DIVISION. 365 



Among 380 skulls of apes and monkeys ^ in the Department 

 of Biology of the Museum, 

 in which the malar sutures 

 are clearly traceable, there 

 are three, a Macaque, a Cer- 

 copithecus, and a Chryso- 

 thrix, with malar division. 



(b) Macacus pelops, 

 male, adult. No. 22,062. 

 The right malar shows an 

 oblique, serrated division, 

 running dorsally from a 

 short distance above the 

 lower end of the malo- 

 maxillary suture to the F»- ^-DivWed right maiar of .jw^^././^/^^ Nat- 

 curving superior border of 



the zygoma (Fig. 3). The ventral part of the suture lies in 

 nearly the same position. On the left is found dorsally a 4 mm. 

 long suture, beginning from the malo-maxillary suture in a simi- 

 lar position as that on the right side. The two malars are equally 

 high and long. The skull shows no 

 other anomalies. 



(c) Cercopithecus callitrichus, male, 

 adolescent. No. 16, 365. The right 

 zygomatic process is posteriorly com- 

 pleted by a triangular portion, separated 



riorly the border of the malar ])ortion of 

 F.c. 4.- Divided zygomatic pro- the arch just touchcs that of the tempo- 

 xLraUifr'''''''"" ral portion, inferiorl\- the two are sei)a- 



rated by a distance of 12 mm. (Fig. 4.) The supernuirierary 

 suture is serrated and equally well distinct \entrall\ . It is very 

 plainly anomalous in character; there is not the sli^ditest trace
