In the more recent or diluvial formations a fossil species 
of EHquus, 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 
dissociated remains of extinct Mammals with which they 
had clearly been contemporaneous. 
In the collection of Miss Gurney of Northrepps Cottage, 
near Cromer, I saw a fossil second phalanx, or pastern 
bone, of a small species of Hquus, about the size of the 
Zebra, from the pliocene crag at Thorpe. Dr. Mantell 
states that teeth and bones of an Hquus, from the super- 
cretaceous drift. deposits, which, on account of the abundant
