and the intermediate gradations in the fossil molars, by 
which such rare extreme varieties are linked to the normal 
type of the Mammoth’s dentition, give cause for rejecting 
the conclusion that the Hlephas Indicus co-existed with 
the Mammoth in the latitude of England during the an- 
tediluvial or anteglacial epoch: and I think it probable 
that such differences as have been pointed out in the 
molar from the Museum of Parkinson, and that of the 
existing Elephant, might likewise have been detected in- 
the large molar, found at the depth of six feet in brick 
loam, at Hove near Brighton, and alluded to by Dr. 
Mantell as decidedly that of the Asiatic Klephant.* One 
of the molars from the Elephant bed at Brighton, now in 
the possession of Mr. Stone of Garlick Hill, exhibits the 
narrow-plated variety of the Mammoth’s grinder. 
The molars of the Mammoth generally contain a greater 
proportion of cement in the intervals of the plates than the 
Indian Elephant’s grinders do. Those in which the plates 
are more numerous have the enamel less strongly plicated ; 
but in some of the large molar teeth of old Mammoths 
with the thicker plates, as in fig. 90, the enamel is as 
strongly festooned as in the teeth of the Indian Elephant. 
The bones of the Mammoth that have hitherto been 
disinterred, present no variations from the characteristic 
extinct type indicative of distinct species; and it might 
reasonably have been expected that the lower jaw, for 
example, with the broad-plated tooth should have offered as 
recognizable differences from that with the narrow-plated 
teeth, as this does from the lower jaw of the Indian Ele- 
phant, if those modifications of the teeth of the Mammoth 
indicated distinct species. The lower jaw, however, of 
the ancient British Mammoth has the same distinctive
