seas during Eocene and Miocene times, five of the molluscs 

 are included in Mr. Johnston's list ; moreover, I stated that 

 " other fossils have been referred to living species — to Trivia 

 Europceay Leiostraca suhulata, Lima suhauriculata, Liotia 

 lamellosa, etc., but competent authorities have not confirmed 

 these identifications." The references in the above quotation 

 chiefly concern the Tasmanian geologist, and, as regards the 

 first three species, I have the testimony of Mr. Gwyn 

 Jeffreys, F.R.S., — a specialist in European conchology — that 

 the Tasmanian fossils do not belong to the existing species to 

 which they have respectively been referred. He writes, " I 

 have carefully compared these fossil specimens with recent 

 ones bearing similar names from different parts of the 

 European seas. I regret that I cannot acquiesce with Mr. 

 Woods' identifications." 



In the accompanying table I have set side by side the 

 Table Cape fossil species and the recent forms with which 

 some of them have been confounded ; the names of the fossil 

 species represented in living creation are printed in italic. It 

 must not be supposed that seven species only are in common 

 between the older tertiary fauna of Australia and the recent 

 one, as a much greater amount of material awaits elaboration 

 than has already been scrutinised, and which may presumably 

 yield a few species having living identities.
