E. (LOXODON) MEEIDIONALIS. 137 



wear and a talon. The crown is ground down low, the inter- 

 spaces of cement are very wide, and the annular discs of the 

 digitations are so thick as to approach the character of the 

 worn ridges of some of the Stegodons. 

 The dimensions are : — 



Length of the fragment, 2 p 7 in. Width of crown, 4-2 in. 



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

 the valleys. It bears the appearance of a Mundesley spe- 

 cimen. 



Of the upper molars, the figured specimens in PI. XIY. 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 

 Pala3ontol. Cat. No. 7456), comprising the remains of ten 

 discs of wear, ground down nearly to their common base. 

 The central discs exhibit a certain amount of open crimping. 

 The specimen is also remarkable for the breadth of the 

 crown ; it is understood to have been derived from the 

 ' Oyster-bed ' of Mundesley or Happisburgh. 



The dimensions are: — 



Length of crown, 8-2 in. Width of crown, 4 - 3 in. 



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 discs ; the 

 posterior four exhibit rings that are not confluent. There is 

 a talon behind enveloped by cement. In front of the first 

 remaining disc there is a broad depressed surface of ivory, 

 indicating the position of two or three worn-out discs in 

 front. The discs are expanded, with a slight tendency to a 

 crescentic bend, the cornua being bent forwards. The plates 

 of enamel are very thick, and deeply channeled exteriorly, 

 so that there is a spurious appearance of crimping on that 

 surface ; but the edges in contact 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). 



The dimensions are : — 



Length of crown, 9 - 2 in. Width of crown at second remaining ridge, 3'6 in. 



The antero-posterior convexity of the grinding-surface deter- 

 mines the tooth to be an upper molar. (See PI. VIII. fig. 4.)
