238 PROBOSCIDIA. 



thick-plated molars as a distinct species, which V. Meyer 

 in his work cites as the Elephas meridionalis. In regard, 

 however, to the proposed distinctive name, I may remark 

 that the variety of molar on which this species is founded, 

 occurs not only in England, but in Siberia, and as far north 

 as Eschscholtz Bay.'* 



Most of the molars of the Mammoth from North Ame- 

 rica are characterized by thinner and more numerous plates 

 than those of England, but the difference is not constant. 

 The Mammoth's molar from the Norfolk coast in the 

 collection of Miss Gurney, which shows nineteen plates 

 in a length of ten inches, equals several of the molars from 

 North America in the number of the plates. An upper 

 molar of a Mammoth from the gravel of Ballingdon, with 

 a total antero-posterior diameter of seven inches, consists 

 of twenty plates. Mr. Parkinson describes a molar tooth, 

 now in the Museum of the College of Surgeons, from 

 Wellsbourne in Warwickshire, in which twenty plates 

 exist in a length of six inches and a half; and he figures 

 another molar from the till of Essex, which, in a length 

 of eight inches and a half, contains twenty-four plates. 

 The proportions of the figure in the ' Organic Remains, 1 

 not being quite accurate, I have given two original views of 

 this remarkable molar, (figs. 91 and 92,) which appears to 

 have been the fifth in succession in the upper jaw. On 

 the other hand, the molars of the Mammoths from 

 Eschscholtz Bay, North America, figured by Dr. Buckland, 

 manifest the same kind of variety as those from the Eng- 

 lish drift ; one with a grinding surface, seven inches and 

 a half long, exhibiting nineteen plates, whilst another in 

 the same extent of grinding surface shows only thirteen
