XXXI. Preliminary Notes on a Post-Tertiary Fresh-Water 

 Deposit at Kirhland, Leven, and at Elie, Fifeshire. By 

 Thomas Scott, F.L.S., Naturalist to the Fishery Board 

 for Scotland. 



(Read 16tli April 1890.) 



Since the publication of the paper on " The Ancient Lakes 

 of Edinburgh," by Mr James Bennie of the Geological Survey 

 and myself,^ considerable additional information has been 

 collected (solely by Mr Bennie), relating not only to the 

 deposits referred to in that paper, but also to others of a 

 similar character, either unknown to us when the paper was 

 published, or our knowledge of which was not sufficiently 

 full to enable us to include them in it. I anticipate that 

 this additional information will probably be submitted to the 

 Eoyal Physical Society during the next session. Meantime 

 it has been considered desirable that the following notes on 

 various species of MoUusca and Crustacea that have recently 

 been observed in a post-Tertiary marl, at the Kirkland of 

 Leven, and in a bed of loam at Elie station, should be now 

 recorded. 



I propose in the remarks I have to offer on these two 

 deposits to refer to each separately, as by doing so a clearer 

 idea will be had of the conditions under which each was 

 formed, and it will also facilitate comparison between them. 

 The need for this will become more obvious by an examina- 

 tion of the organic remains taken as a group that have been 

 observed in each deposit. I will refer first to the 



Kirkland Marl. 



This marl occurs in Mr Kirkby's garden at the Kirkland 

 of Leven, and is overlaid by from six to seven feet of sand 

 and gravel, and it is owing to the fact that Mr Kirkby set 

 his boys to dig holes down to it (and they seem to have 

 entered heartily into the work) that samples of it were 

 procured and forwarded to me through my friend Mr James 

 Bennie.
