state of development of the group at the period in which it 

 lived. 



A most interesting circumstance was brought to light when 

 M. Delfortrie's specimen came into the hands of M. Gaudrj, 

 of Paris. That experienced and accurate paleontologist, with 

 the rich treasures of the Paris Museum at his hand for com- 

 parison, recognized that certain more or less fragmentary 

 specimens which had long been in the collection, and had 

 been described from the teeth alone, and generally, though 

 doubtfully, referred to the Ungulata, were really nothing more 

 than animals of the same group, and probably even the same 

 species SLsFalceolemur Betillei. These are: — Adajns parisiensis^ 

 Cuvier, from the Paris gypsum, described and figured in the 

 * Ossemens Fossiles ;' Aphelotherium Duvernoyi^ Gervais, from 

 the same beds ; and other specimens from Barthelemy, near 

 Apt, This result is fully acquiesced in by Gervais *, who 

 also adds CcBnoptthecus lemuroides^ Riitimeyer, to the syno- 

 nyms of the animal, which must henceforth be called Adapts 

 parisiensis, as tliat was the first name assigned to it. 



M. Delfortrie's announcement of a fossil lemur from the south 

 of France was soon followed by that of another species by M. H. 

 Filhol, named Necrolemur antiquus ('Comptes Rendus,' 1873, 

 tome Ixxvii. p. 1111), which was afterwards more fully de- 

 scribed and figured in an important memoir f, in which the 

 Lemurian affinities of Adapts are criticised, and a second and 

 considerably larger species. Adapts magnus, Filhol, found in 

 phosphatic deposits at Raynal, added to the group. The latter, 

 of which the skull was upwards of four inches in length, re- 

 sembles M. Delfortrie's in its general characters, but modified 

 much in the way that the skulls of larger animals of natural 

 groups differ from the smaller ones. The brain-chamber and 

 orbits are relatively smaller, the face larger, the muscular 

 crests more developed, the constriction between the cerebral 

 and facial portions of the skull more marked. These modi- 

 fications remove the skull in its general characters still further 

 from the existing Lemurs — so much so that M. Filhol refers 

 it and the other species of Adapts to a distinct and hitherto 

 unknown zoological type, intermediate between the Lemurs 

 and the Pachyderms, to which he gives the name of Pachy- 

 lemur. On the other hand, the Necrolemur antiquus found 

 at St. Antonin, which is a very small species, scarcely ex- 

 ceeding the smallest living Lemur [Chirogaleus rufus) in size,
