Indian specimfens form a separate variety on this character is to 

 some extent justified *, and has at least as much to commend it,

" Species" and "subspecies" have little significance in palseon- 



* A close appi'oacli, liowevev. to the Indian teeth is fig-ured by Wegner (Pala;on- 

 tographica, vol. Ix. 1913, pi. xv. figs. 3 & 4). This specimen is move advanced in 

 its larger talon, and has a number of accessory cusps in the first vallc^^ The second 

 and third valleys, however, are like the Indian form except that the cusps of the 

 fourth ridge are fully divided into two each. Weguer's specimens, an upper as well 

 as a lower molar, come from the Upper Miocene of Doppeln, and though more 

 advanced than the Indian form, are constructed on somewhat the same plan. Wegner 

 notices the same difference between his forms and specimens from Sansau as is 

 noticed here.
