158 Dr. C. J. F, Major on Fossil Quadrumana. 



in the two species before me, of which the teeth are not much 

 worn, there is only an impaired terminal talon. 



I may remark here that the last lower molar of some species 

 of Macaques, such as Macacus (Inuus) ecandatus^ is charac- 

 terized by a terminal talon subdivided into three parts, whilst 

 in others there are only two divisions. With regard to the 

 SemnojntJieci it is only in young individuals that we see a 

 faint indication of a division of the terminal talon, which occurs 

 somewhat approximated to the inner side, whilst in Colohus 

 guereza it occupies more nearly the middle of the posterior 

 margin ; this is the only difference which I have been able to 

 detect in the dentition of the two genera. Thus it would appear 

 that it is only with some reservation that the determination 

 given by M. Fraas must be accepted. 



It is in the deposit of Pikermi, in Attica, that the most 

 numerous remains of Quadrumana have been found, but 

 always represented by a single species, Mesopitltecns jjenfeUciy 

 A. Wagn., which possesses the cranium and dentition of the 

 Semnopitheci and the limbs of Macacus'^. Of this M. Gaudry 

 sent to Paris the remains of twenty-five individuals ; at 

 Munich there are also numerous remains of it, and the 

 Museum of Milan possesses some fine crania. 



I will conclude the examination of the Miocene Monkeys 

 by referring to the discovery in the sands of Eppelslieim 

 (Rhenish Hesse) of a fossil ascribed to a monkey f. E]>pels- 

 heim is of the same age as Pikermi ; it is therefore possible 

 that the same species may occur in both localities ; neverthe- 

 less it would appear that the remains found at Eppelslieim 

 are not sufficient to allow of exact determination. 



Monkeys from Dejwsits more recent than the Miocene. — The 

 name of Macacus plioco^nus was given by Prof. Owen to a 

 fragment of a maxillary containing the penultimate right upper 

 molar, most nearly resembling the corresponding tooth of 

 Macacus sinicus. The deposit in which the specimen was 

 found is a bed of yellowish sand between two beds of brick- 

 earth situated near the village of Gray's Thurrock, in the 

 county of Essex :|:. M. Beyrich thinks that the denomina-
