Hugh Miller has so fully described this interesting locality, 
that little more can be said about it than is stated in 
“Kdinburgh and its Neighbourhood.” 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 Planorbis, 
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 Limnca ; 
neither have we been able to recognise Planorbis glaber, 
mentioned by R. 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 where 
Daruinula has been observed living: Loch Fell, Wigtown- 
shire ; Lochs Aber and Ruter, and White and Borean Lochs, 
Kirkeudbrightshire ; Broom Loch, Dumfriesshire; and Loch 
Mack, near Oban. Darwinula seems to have been of frequent
