in St. Andrews Bay. Six species are described by G. C. Bourne, 
M.A., F.L.S., in the ''Quarterly Journal of Microscopical Science," 
vol. XXX., N.S. (1890). Another is described by I. C. Thompson 
in Trans. Biol. Soc, Liverpool, vol. iv.^ 
Daphnia sp. In the tow-net material from Loch Mullach Corrie 
in which Diaptomus serricornis occurred, a species of Daphnia 
was obtained that differs somewhat from any I have previously 
observed in Scotch inland waters. It comes near Daphnia pulex, 
but may be distinguished by the spine at the extremity of the 
valves of the carapace being black. The terminal joints of the 
setae of the antennae are also of a black colour. 
Graptoleberis (Lynceus) testudinaria (Fischer). This 
pretty but rather small Cladoceran was taken by hand-net in 
Lochend Loch, Edinburgh, some time ago. Although apparently 
of frequent occurrence in some parts of Britain, I have failed to 
observe it in the tow-nettings from Scotch lochs examined by me, 
except Lochend Loch and Loch Mullach Corrie, where it also 
occurred. It is readily distinguished from other British Lynceidae 
by its large, erect, hood-like head, which incloses the antennules, 
straight ventral margin, and the two or three — usually three — 
comparatively large teeth at the ventral angle of the carapace. 
Its small size may cause it to be frequently overlooked, its length 
being scarcely the 40th of an inch. It frequents lochs where the 
water is pure and bright. 
1 Thompson also (loc. cit.) discusses the classification oi Monstrilla.
