.24 NOTES ON THE MAMMALS OF TASMANIA, 



has pointed out, the^ teeth vary greatly in the same species, 

 not only on account of age and sex but on account of the 

 type of food that the animal has been forced to make use 

 of. I have just examined a series of specimens that amply 

 demonstrate this. Space will not permit the matter being 

 fully discussed in the present instance, but on the material 

 al present available I propose to credit Tasmania with one 

 member of the Otariidae, as it appears probable that the 

 few survivors (of a once beautiful species) (1) that exist 

 around the shores of Tasimania may be grouped under the 

 one head. (2) But even now a further difficulty exists, and 

 that is to choose one designation from many that might be 

 attached to this species. After investigating the que;-tion 

 as fair as the material available permittied I have resolved 

 to adopt the designation Eutaria cinerea. 



Seals are still to be Hiet with in Bass Straits, and I 

 knoiw of several isolated rocks on the Southern and Eastern 

 Coasts where seaJs can usually be seen. I hope at a future 

 date to obtain specimens for examination.
