ELEPHANT AND MASTODON. 129 



appeJiring to be large and composed of cellular bone. The angle 

 formed by the tusks with the grinding surface is more obtuse than in 

 the existing elephant, and the form of head, instead of possessing the 

 proportion assimilating the skull of the elephant to that of man, may- 

 be considered as nearly square, or perhaps possessing a breadth in 

 greater proportion than the length. The height of the maxillary 

 bones, which is great in the elephant, is here much exaggerated, and 

 the form and profile especially is so peculiar, that a glance at the 

 sketch will, by comparison with that of the existing elephant also 

 given, be sufficiently striking. 



The suborbitary tbramen is by no means large ; the proportion of 

 diploe in the upper part of the cranium bears no comparison with 

 that in the existing elephant, these differences, combined with the 

 peculiarity of form and position of the external nasal aperture, may, 

 in all probability, modify the extent to which this variety of Mastodon 

 was provided with a trunk; but to forbear from surmises or speculations 

 in the present imperfect state of the inquiry, it will be sufficient to 

 place this as a second to the angiistidens formerly noted. 



P.S. — A letter this moment received from Captain Cautley an- 

 nounces the discovery of a superb specimen of the Mastodon angusti- 

 dens, a skull with both lines of molars, palate, and one orbit entire.' 

 He adds : ' We have much still to learn of these Mastodons. With 

 regard to the Mastodon elephantoules of Clift, there are evidently two 

 species, of the same character as to dentition, but with a remarkable 

 difference in the form of the cranium, one of which has the flat and 

 the other the elevated crown.' — Ed. Journ. As. Soc.

 lensis is represented iu PI. x., which is | tiqua Sivalensis. — [Ed.]
