Land and Fresh- Water Crustacea around Edinburgh. 53 
The first, Cypris bispinosa, is one of the finest of the 
British species, and the only other two places where it has 
been observed are the island of Guernsey and Egypt; while 
the second, Candona elongata, has been obtained nowhere 
else,—its Ivish habitat being Lough Neagh. 
LocaL LISTS OF SPECIES. 
The following lists of species are intended to exhibit how 
the Ostracoda vary in number and kinds in different localities 
in the district, and, also, to show that, while some forms are 
more or less common to all the localities, others are restricted 
to one or to only a few places. ‘The lists may also be of use 
to collectors, by indicating where the rarer species may be 
obtained, and where the richest gatherings have been made. 
A few of the species mentioned in this paper are more 
frequently obtained in brackish than in purely fresh water, 
but they are included because of their close relationship 
with true fresh-water species. The true fresh-water and the 
true marine species merge together in these brackish-water 
forms, and any boundary line that may be drawn between 
the two is at best more or less arbitrary. 
As Duddingston Loch is in our immediate vicinity, and 
has, so far, yielded a greater number of species than 
any other locality within the district, it may be better 
first to give a list of the Ostracoda that have been obtained 
in this loch. |
