Fossil Fauna, Table Cape Beds, Tasmania. 75 



Upon asking the former curator, Mr. F. J\r. Krause, who was 

 responsible for the naming of the Ballarat collection, he informed 

 me that it was examined and named by himself. 



There appear, however, to be only three additional species to 

 those in the Atkinson collection, and these I have referred to in 

 what follows. 



Having gone so far, I have thought it well to add as an 

 appendix as complete a list as possilile of the records from these 

 beds. This appended list includes 114 species, and in the classes 

 I have not touched in this paper Mr. R. M. Johnston records 

 twenty-three species. We have thus the grand total of 281 

 species referable to this horizon. The complete summary being — 



Manunalia ------ 1 



Pisces ------ 3 



Cephalopoda ----- 1 



Gastropoda - - - - - - 153 



Lamellibranchiata - - - - 65 



Brachiopoda - - - - - 17 



Polyzoa ------ 9 



Echinodermata ----- 3 



Zoantharia - - - - - - 19 



Foraminifera - - - - - 10 



281 



From this it can be seen that we have 219 species of mollusca 

 proper, and included amongst these there are seven living species. 

 As, however, two of the latter, namely, Limopsis aurita and 

 Chamostrea albida, aie exceedingly doubtful records, it is, T 

 think, reasonable to leave them out of consideration for the 

 present. Taking into account, then, the remaining five, the 

 percentage of living species for these beds is just about a fourth 

 over two per cent. 



When it is taken into consideration that as many as twenty 

 different living molluscan species have been recorded as occurring 

 in these beds, and that subsequent examination of the shells 

 has brought this list down to the above, we are not surprised at 

 the confusion that has existed as to the age of the beds.
