The specimen (fig, 93), is the posterior part of a largegrinder, apparently the last of the upper jaw, of an old Mam-moth. The superior thickness of the plates arises from thecircumstance of the posterior plates being thicker than theanterior ones; these thick plates are more deeply cleft, ortheir digitated summits are longer, and advance further for- * Organic Remains, iii. p. 344. 240 PROBOSCIDIA. ward upon the grinding surtace of tlie molar before they areworn down to their common base; they appear also in thespecimen to be more advanced than they really are, becauseof the deficiency of the fore-part of t
