This is also a characteristic specimen of E. meridionalis. 



Figs. 12 and 12 a represent a very notable fragment of the pos- 

 terior end of a last lower molar, comprising two disks of wear and a 

 talon. The crown is ground down low, the interspaces of cement 

 are very wide, and the annular disks of the digitations are so thick 

 as to approach the character of the worn ridges of some of the 

 Stegodons. 



The dimensions are —

A solitary digitation is situated at the outer side of one of the 

 valleys. It bears the appearance of a Mundesley specimen. 



Of the upper molars the figured specimens in PI. 14 B are less 

 numerous ; but, during the twelve years which have elapsed since it 

 was struck off, many specimens have been amassed in the Norfolk 

 collections which could furnish complete illustrations of the upper 

 series. I shall confine myself to the figured specimens. 



Figs. 13 and 13 a represent a mutilated fragment of a very old 

 molar in the collection of the British Museum (Old Palaeontol. Cat. 

 no. 7456), comprising the remains of ten disks of wear, ground 

 down nearly to their common base. The central disks exhibit a 

 certain amount of open crimping. Tlie s]3ecimen is also remarkable 

 for the breadth of the crown ; it is understood to have been derived 

 from the " Oyster-bed " of Mundesley or Happisburgh.

I regard it as being of E. meridionalis. 



Figs. 14 and 14 a represent the crown of a fine last upper molar, 

 left side, of a very old animal, and in an advanced stage of wear. 

 There are nine ridges remaining, the first five of which are ground 

 down into transverse disks ; the posterior four exhibit rings that are 

 not confluent. There is a talon behind enveloped by cement. In 

 front of the first remaining disk there is a broad depressed surface 

 of ivory, indicating the position of two or three worn-out disks in 

 front. The disks are expanded, with a slight tendency to a crescentic 

 bend, the cornua being bent forwards. The plates of enamel are 

 very thick, and deeply channelled exteriorly, so that there is a spu- 

 rious appearance of crimping on that sui'face ; but the edges in con- 

 tact with the cores of ivory are unplaited. The specimen in its 

 mineral condition is black and heavy. It is understood to have 

 belonged to Woodward (Norwich Museum).
