obvious, therefore, that this Haverfordwest species belongs to tliis^ 

 group of Btilmaniles, in which there existerl a combination of the 

 subsequently well - diiFerentiated characters of the later typical 

 Dalmanites and Phacops. 



The specific name, PJi. Bobertsi, has been chosen in memory of 

 the late Mr. T. Roberts, M.A., F.G.S.

Part I. 



DURING the last few months I have been engaged in examining 

 the remains of the fossil Vertebrates from the Middle and 

 Upper Eocene ot the Eayiiin district of Egypt, with a view to tlie 

 preparation of the detailed monograph which it is proposed to publish 

 on this subject. As it will be some months before this can appear, 

 it seems desirable to give a brief account of some of the more 

 important results arrived at, and preliminary descriptions of such 

 new forms as have come to light in the course of the work. The 

 collections examined include all the material belonging to the 

 Britisli Museum, as well as many of the more important specimens 

 from the Geological Museum of Cairo. There still remains in Cairo 

 a large collection of bones, which I hope to have an opportunity 

 of working out during the next few weeks. 



Mceritherinm. 



The figure of the skull and mandible of Mceritherinm lyonsi lately 

 published (Phil. Trans., vol. 196 B, figs. 14-17) was reconstructed 

 from portions of a number of skulls from the Middle Eocene. Since 

 then Mr. H. J. L. Beadnell has found an almost complete skull of 

 a nearly adult animal from the Upper Eocene, and from this the 

 accompanying restoration (Fig. 1) has been made, showing the 

 boundaries of many of the bones, but otherwise diifering in no 

 important points from the earlier figure. The mandible has been 

 reconstructed from several Middle Eocene specimens. 



The most striking character of the skull as a whole is the great 

 elongation of the ci'anial as compared to the facial region. The
