extent of the pulp-cavity, it is believed to have belonged to a nearly 

 adult individual and indicates a tooth of small size, though its 

 condition is too imperfect to admit of any measurements being- 

 given other than its approximate diameter, which is 46 mm. 



Ux>2^er Molars. — Only two of the nine molars are considered to 

 belong to the upper series ; the smaller of these (M. 9376), n.Jirst 

 • true molar, is split longitudinally almost in half, biit sufficient 

 i-emains to show the general character of the tooth. It consists 

 of seven plates, though it is possible that an additional small 

 anteiior ridge was originally present. Its antero-posteiioi- length 

 is 54 mm. and height about 32 mm., although the fangs extended 

 for a short distance further, bringing the total measurement up 

 to 41 mm. Comparatively sjjeaking, the height of this tooth is 

 slightly greater than in most of the other specimens referred to 

 E. creUcus ; this is an argument in favour of its being a first true 

 molar rather than the last of the milk-series, which, from its size 

 alone, it might perhaps have been thought to represent. The 

 enamel bands are not very thick and in several of the ridges are 

 somewhat broken up into " rings"; at the same time, the cement- 

 areas are broad, a character generally found in conjunction with 

 more massive enamel. In section this tooth shows that the cement- 

 areas maintain an almost uniform width for nearly the whole of 

 their extent. This feature is probably not infrequent in the 

 molars of this species, as suggestively exemplified by some of the 

 extensively worn specimens described below. 



The Cretan specimen is supei-ior in antero-posterior length to an 

 example of the corresponding tooth of ^. cyjyriotes (M. 8602) *, 

 though this latter exceeds it in the height of its crown, which 

 is 53"5 mm. ; this difference in the proportions is eA'en more 

 marked in a molar of E. melitensis (44252) \. 



The second specimen (M. 9377, PL XIII. fig. 2), believed to 

 belong to the upper series, is of larger proportions than the last, 

 and is much worn and somewhat damaged ; it probably represents 

 the penultimate triie onolar. It is difficult to say of how many plates 

 it originally consisted, but it can be seen that there were at least 

 eight, all of which were in iise, the front ones being worn down 

 almost to their common base, while a portion of the anterior ridge 

 is broken off. Partly owing to its advanced state of wear, the 

 crown is very wide, being 37 mm. across, while its antero-posterior 

 length is 77 mm. and its height 37 mm., though this would 

 of covirse have been greater when the tooth was still but slightly 

 abraded. In spite of the condition of this molar the cement-areas 

 are still broad, equalling or even exceeding in size the plates of 

 dentine ; the enamel bands are thick and in a few instances 

 somewhat wavy in outline. 



Although apparently considerably superior in height of crown, 

 this tooth in E. Cypriotes is otherwise decidedly smaller than the 

 above, the dimensions of a much less worn example (M. 8601)
