traced under the overlying sediments, represent the former out- 

 line of the miocene coast, only, instead of being nearly a straight 

 line, it might perhaps prove to be as much broken by indentations 

 as the present northern shores of the lakes. 



Appended is a list of the species obtained from the various 

 sections in the area since the publication of the previous article. 

 In all, fifty-one additional species are here recorded, which bring 

 up the total number now known from the beds to 167. A large 

 proportion of the more recent gatherings are, so far, restricted 

 to these beds ; seven of the species are also constituents of the 

 miocene fauna of Muddy Creek, while three or four, if not more, 

 are still living in the adjoining seas. 



Many of the new species here referred to are very handsome, 

 and we hope before long they will be described in the Proceedings 

 of the Society ; among them are included a tine large volute, two 

 elegant niangilins, one or two new tritons, a trigonostoma, new 

 species of marginella, and a markedly distinct species of the 

 curious little coral, for which the genus Treiiiatoirochus was 

 established by Tenison Woods. 



In the former publication, the proportion of recent species 

 <.)f mollusca was estimated at sixteen per cent., and by omitting, 

 as was done before, a few in the present list which are too worn 

 for accurate identification, the percentage remains practically the 

 .same ; it is certainly not increased. 



The opportunity is now taken of making some necessary 

 corrections in the 1890 list, as indicated in the columns below: —
