IN the more recent or diluvial formations a fossil species 

 of Equws, smaller than either of the preceding and about 

 the size of the Wild Ass, is indicated by molar teeth. 

 Of these I have examined a middle molar of the left side 

 of the upper jaw, from the drift overlying the London clay 

 at Chatham ; a corresponding molar from the opposite 

 side of the upper jaw (fig. 157), from the drift at Kes- 

 singland in Suffolk ; the last upper molar (fig. 158), from 

 the same deposit and locality ; and a fifth molar, left side 

 of lower jaw, from a cavernous fissure at Oreston : all 

 these teeth were in the same fossilized condition as the 

 associated remains of extinct Mammals with which they 

 had clearly been contemporaneous. 



In the collection of Miss Grurney of Northrepps Cottage, 

 near Cromer, I saw a fossil second phalanx, or pastern 

 bone, of a small species of Equus, about the size of the 

 Zebra, from the pliocene crag at Thorpe. Dr. Mantell 

 states that teeth and bones of an Equus, from the super- 

 cretaceous drift deposits, which, on account of the abundant
