I. — Notes on sojie New Crocodilia from the Eocene of Egypt. 

 By C. "W. Andrews, D.Sc, F.G.S., British Museum (Natural History). 

 kURING the last few years a considerable number of Crocodilian 



remains have been collected from the Middle and Upper Eocene 

 beds of the Fayiim, most of these specimens having been obtained 

 by Mr. H. J. L. Beadnell in the course of his excavations in that 

 locality. This material has recently been examined and determined, 

 and it is found that several new species belonging to the genera 

 Crocodihis and Tomistoma are represented by more or less complete 

 remains. In the present note it is proposed to give a preliminary 

 account of these new forms, which will be fully described and 

 figured in the Catalogue of the Tertiary Vertebrata of the Fayiim 

 now in course of preparation. 



The species of Crocodihis now described belong both to the broad- 

 and narrow-snouted divisions of that genus. 



Ckocodilus articeps, n.sp. 



Of the latter group only one species has been found ; this is 

 represented by an extremely well-preserved skull wanting the 

 posterior region. This skull, which is from the Upper Eocene 

 beds, is taken as the type-specimen. A very perfect mandible from 

 the same horizon and locality probably belongs to the same species. 



The general form of the head is much the same as in C. cata- 

 phractus, the length of the snout being about two and a half times 

 its breadth at the orbits. The upper surface in the pre-orbital 

 region is somewhat flattened, while the sides are nearly vertical. 

 There is scarcely any expansion of the premaxillary region; the 

 facial processes of the premaxillee extend back to the level of the 

 third maxillary tooth, while the palatine processes reach only to 

 the level of the interval between the first and second teeth. The 

 maxillo-premaxillary suture on the palate is directed backwards. 

 The nasals extend just to the nasal opening, though whether thev
