On pp. 10 and 18 the author gives the characteristics 

 of the genus Miopitheciis. 



During my recent visit to the Musea of Paris and London, 

 for other purposes, I was kindly allowed to examine by 

 the way the skulls and skeletons of Talapoins. The exami- 

 nation of aforesaid materials, as well as the comparison 

 of the Leyden skulls with those of other Cercopitheci , has 

 led me to the following conclusions: 



On the fifth or last molar of the lower mandible 

 of adult specimens there are four tubercles , while on the 

 same molar of the upper mandible the hindmost tuber- 

 cles are very small , the crown showing a strong inclina- 

 tion of becoming narrowed posteriorly, a character which 

 is also found in the dentition of some other Cercopitheci. 



The foramen occipitale agrees as regards its measure- 

 ments with that of other species. 



Like in the skull of other Cercopitheci, the nostrils 

 reach a little higher than the basis of the orbita. 



The transparancy of the os internasale may not be con- 

 sidered to be a character of specific value. An examination 

 of different species of Cercopithecus shows that in some 

 specimens the os internasale is transparent, while in other 

 ones this is not the case. I hardly need to say that much 

 care is indicated in studying bones of animals which have 

 lived in Menageries or Zoological Gardens. 



The habitus of the skull does not differ from that of 

 the other Cercopitheci.
