E. (EUELEPHAS) INDICUS. 153 



and back talons, making in all fourteen divisions. The five 

 anterior ridges and talon are worn, the rest being intact. 

 The dimensions are : — length of crown 6*8 inches, width of 

 ditto in front 2*4 inches. 



In the lower jaw of the same cranium, the last milk molar 

 is nearly worn out ; the antepenultimate true molar has a 

 crown composed of twelve principal ridges, with front and 

 back talons, the latter of which has a small splent appended 

 to it. The ridges may therefore be reckoned either as 12 or 

 13, according to the different views of observers in regard to 

 what ought to be considered talons. The eight anterior 

 ridges of the crown are in full wear. The length of the crown 

 is 7 "8 inches. 



I have now before me two very instructive detached speci- 

 mens, belonging to the collection of my coadjutor, Colonel 

 Sir Proby Cautley, and consisting of the right upper and lower 

 antepenultimate true molars of the same animals. They are 

 in the most favourable state of use for observing all the cha- 

 racters. The upper molar has a crown composed of twelve 

 well-defined principal ridges, with a front and back talon. 

 The seven anterior ridges are in wear, presenting open trans- 

 verse discs with the enamel-borders strongly crimped. The 

 posterior talon consists of a narrow splent appended to the Jast 

 ridge. The dimensions are : — 



Length of crown, 7 in. Width of ditto at second ridge, 2-5 in. Width of ditto 

 at eighth ridge, 2'5 in. Width of ditto at eleventh ridge, 2 - 2 in. Height of ditto 

 at seventh ridge, €i - 9 in. 



The corresponding tooth of the lower jaw presents a crown 

 also having twelve principal ridges, with a distinct front and 

 back talon. The nine anterior ridges are in use, the front 

 talon in this instance, as also in the upper tooth, being con- 

 fluent with the disc of the anterior ridge ; the posterior talon 

 is a narrow splent. The discs of wear are transverse, open 

 and free from mesial dilatation, and the enamel -plates are well 

 crimped as in the upper molars. The dimensions are : — 



Length of crown, 7'5 in. Width of ditto at second ridge, 2-1 in. Width of 

 ditto at eighth ridge, 2-4 in. Height of ditto at ninth ridge, 5 - 6 in. 



In these two specimens the character which most obviously 

 distinguishes the Euelephants from the Losodons is well 

 manifested, namely, the great height of the crown relatively 

 to the width. In the upper antepenultimate, the height of 

 the seventh ridge is almost equal to the length of the crown. 

 The dimensions of these teeth render it certain that they are 

 not the last milk molars.
