FELID.E. 41 



present writer thinks it may possibly be intermediate between some 

 of the Carnivora Primigenia (like the N. American Mesowyx} and 

 the Carnivora Yera. The brain-case is larger than in Mesonyx, and 

 the dentition less numerous and more macrodont. 



Argillotherium toliapicum, Davies l . 

 Hob. England. 



35688. Part of the cranium, showing portions of the parietals, the 

 maxillae, palatals, pterygoids, and presphenoid ; from the 

 Lower Eocene (London Clay) of the Isle of Sheppey. The 

 alveoli of pm. 3, pm. 4, and m. 1 are shown ; if m - % was 

 present it must have been very small. This specimen is 

 the type, and is described by Davies in the passage cited. 



Purchased, 1859. 



Suborder CARNIVORA VERA. 



The true Carnivora which come nearest to the Carnivora Primi- 

 genia are some of the Yiverro-canoids ; but it is necessary that these 

 should be placed near the middle of the suborder. The juxtaposition 

 of the Felidse to the Carnivora Primigenia does not therefore indi- 

 cate any close relationship between the two. 



Family FELID^E. 



This family is taken to include the Nimravidce of Cope as well 



as the typical felines 2 .
