section of the eoge of the permanent succeeding tooth below it ; 

 there is no germ below the next tooth, whose roots are much 

 hirger and straighter. This tooth fits the fi-ont tooth of the two 

 upper molars mentioned above. 



A second specimen shows two lower molars well worn, of which 

 the first is about the same size as the first true molars of the 

 previous specimen. The fragment is broken away underneath, 

 and the roots show that tliey belong undoubtedly to permanent 

 teetli.

 therium modia.im in size as well as in shape. The attribution of 

 the present species to the genus is tentative.
