154 Dr. C. J. F. Major on Fossil Quadrumana. 



does not seem to me, at present at least, sufficiently well- 

 fomided. The mandibular teeth of the supposed Hyracotherium 

 cuniculus certainly present more analogy with the Macaques 

 than with Pliolophus vulpiceps (and this, indeed, is admitted by 

 Prof. Owen himself) ; and as regards the upper teeth, as Prof. 

 Owen has figured and described them*, they appear to me to 

 present as many affinities with certain Quadrumana as witli 

 the teeth of Hyracotherium leporinwn to which Prof. Owen 

 compares them. ♦ 



In 1862 M. Riitimeyer described a fragment of a monkey 

 derived from the Jura of Soleure, from the siderolitic deposit 

 [Bolinerz) of Egerkingen, which, from the general character 

 of the remains of Mammalia composing its fauna, is regarded 

 as contemporaneous with the Calcaire Grossier of Paris. The 

 fossil in question, which consists of a fragment of the right 

 maxillary furnished with the three true molars, is ascribed 

 by M. Riitimeyer to a monkey which combined the form of 

 cranium characteristic of the Marmosets with the dentition 

 and size of a Mycetes^ at the same time by its dentition 

 reminding us of the Lemuridse f- 



Among the fossil rodents derived from the same locality, 

 which were intrusted to me some time since by the interven- 

 tion of M. Riitimeyer, there was a left last inferior molar, 

 which I ascribe, although with some doubt, to Cceriopithecus 

 lemuroides, the name given by M. Riitimeyer to the monkey 

 from Egerkingen. The difference between this tooth, which 

 I shall shortly publish, and the corresponding molar of My- 

 cetes is not greater than that between the upper molars of this 

 same genus and the teeth described by M. Riitimeyer. The 

 relative size likewise corresponds. 



Miocene Monkeys. — The greater part of the fossil monkeys 

 known up to the present day belong to the Miocene deposits. 

 Dr. Falconer and Sir Proby Cautley were the first | who found 

 remains of monkeys in a fossil state ; their communication 

 upon this discovery, which was made in the probably Miocene 

 strata of the Sewalik Hills in Northern India, bears date 

 November 24, 1836. The astragalus in question agrees per- 

 fectly in size with the same bone in Semnopithecus entellus ;
