The Meadows. 



Hugh Miller has so fully described this interesting locality, 

 that little more can be said about it than is stated in 

 " Edinburgh and its ISTeighbourhood." Molluscan shells have 

 been observed in great abundance in the deposit, and Hugh 

 Miller refers to at least 9 species as having been found while 

 the meadows were being drained. One species of Planorhis, 

 described by him as having " a delicate dorsal keel," which 

 was probably P. complanatus, — a species still common in 

 Lochend and Duddingston Lochs, — we have not seen, and 

 we have only been able to identify one species of Limnma ; 

 neither have w^e been able to recognise Planorhis glaher, 

 mentioned by E. Etheridge, jun., as having been found in 

 this deposit.^ Ostracod remains were not very abundant, 

 but among those observed is Darwinula stevensoni, which 

 has only recently been found as a post-tertiary fossil at 

 Whittlesea, England. 



The following are the only Scotch localities wdiere 

 Darivinula has been observed living : Loch Fell, Wigtown- 

 shire ; Lochs Aber and Euter, and White and Borean Lochs, 

 Kirkcudbrightshire ; Broom Loch, Dumfriesshire ; and Loch 

 Mack, near Oban. Darivinula seems to have been of frequent
