5012. The skull of the Cercopithecus albogularis. 



It is from an animal of a similar immature age. In both these skulls the premaxillary 

 bones articulate with a considerable proportion of the nasals, and the alisphenoid joins the 

 parietal ; in which characters they resemble the skull of the Semnopithecus Entellus. 



Mus. Brit. 



5013. The cranium of a young Monkey (Cercopithecus cephus). 



The deciduous molars and canines are retained, but with the anterior permanent incisors 

 and first and second true molars in place. The calvarium is detached, showing a tumefaction 

 of the right parietal. In the interior of the cranium may be noticed the deep cerebellar fossa 

 of the petrosal, the deep sella with anterior and posterior clinoid processes, the latter uniting 

 above to form a bony arch, and the well-developed crista galli and the deep canal of the rhinen- 

 cephalic fossa. 



Hunterian. 



5014. The skull, with the calvarium removed, of the Purple-faced Monkey (Cercopi- 

 thecus cephalopterus). Presented by Henry Cline, Esq. 



5015. The cranium of apparently the same species of Cercopithecus. Mus. Brit. 



5016. The skull of a male Green Monkey (Cercopithecus sabaus). 



The dentition is nearly complete : the last molar of the left side has not cut the gum in 

 either jaw. 



Hunterian. 



5017. The skull of an immature Green Monkey (Cercopithecus sabceus). Purchased. 



5018. The skeleton of a male Monkey (Cercopithecus). 



The vertebral formula is : 7 cervical, 11 dorsal, 7 lumbar, 2 sacral, and 21 caudal. There 

 is a fabella behind each condyle of the femur. All the permanent teeth, except the last molar 

 (m 3), have come into place. 



The species affording this skeleton is stated in the ' Osteological Catalogue ' of 1832 to have 

 resembled the Malbrouk ; but it is less than the Cercopithecus cynosurus. 



Presented by William Home Cliff, Esq. 



5019. The cranium, longitudinally and vertically bisected, of the Cercopithecus cepha- 

 lopterus. Hunterian. 



5020. The skull, with the deciduous molars and canines retained, of the White- 

 nosed Monkey (Cercopithecus nictitans). Mus. South.
