4 PRIMATES. 



Genus MACACUS, Cuv. and Geoffrey 1 . 

 Syn. Inuus, Geofiroy 2 . 



Macacus pliocenus, Owen 3 . 

 Nab. England. 



M. 1892. Fragment of the right maxilla, with the penultimate true 

 Fig.) molar, in a partially worn condition ; from the Pleistocene 

 of Grays, Essex. This specimen is the type of the species, 

 and is figured by Owen in the passage cited. It appears 

 extremely doubtful whether the specimen is sufficient for 

 the determination even of the genus to which it belonged ; 

 and it is highly probable that it may be specifically iden- 

 tical with one of the existing African species of Macacus 

 or Cercocebus*. Presented by Sir R. Owen, K.C.B., 1884. 



Genus CYNOCEPHALUS, Lacepede 6 . 

 Syn. Papio, Erxleben 6 . 



Cynocephalus subhimalayanus, H. v. Meyer 7 . 

 Syn. Semnopithectts subhimalayanus, H. v. Meyer 8 . 

 Hob. India. 



31157. The greater portion of the right maxilla and premaxilla, 

 (Fig.} showing the root of the zygomatic arch and the inferior 

 border of the orbit, and containing the whole of the five 

 teeth of the cheek-series and the broken base of the 

 canine; from the Pliocene of the Siwalik Hills, India. 

 This specimen is described and figured by Baker and 

 Durand in the ' Journal of the Asiatic Society of Bengal,'

4 Assuming the correctness of the ordinal determination of this specimen (of 

 which there seems no reasonable doubt), it disproves the statement made by 

 Prof. Boyd Dawkins in the Quart. Journ. Geol. Soc. vol. xxxvi. p. 394 (1880), 

 that " the family of Apes passed away from among the European fauna " with 

 the extinction of Macacus florentinus of the Upper Pliocene.
