The five species of Ostracoda obtained in the material from the 
loch at Castlemilk are — 
Cypria ophthalmica (Surine). 
C. levis (O. F. Miiller). 
Erpetocypris veptans (Baird). 
Candona acuminata (Fischer). 
Limnocythere inopinata (Baird). 
With the exception of Candona acuminata, these are all moderately 
common and generally distributed species. Candona acuminata, 
which is comparatively rare, was added to the British fauna only 
_a few years ago, and is fully described and figured in Brady and 
Norman’s excellent Monograph of the Marine and Fresh- Water 
Ostracoda of the North Atlantic and of North-Western Europe. 
The occurrence of this Candona is interesting because of the 
apparent absence of more common and widely distributed species, 
e.g. Candona candida, &e. 
THe CoPEPODA. | 
The species of Copepoda obtained in the material are the 
following :— | 
Eurytemora clausw (Hoek). 
Cyclops thomasi, Forbes. 
C. signatus, Koch. 
C. serrulatus, Fischer. 
C. fimbriatus, Fischer. 
Canthocamptus minutus (Miller). 
Eurytemora clausit is of frequent occurrence in the material, and 
is a very interesting find. It has been recorded from various _- 
localities in England, and from the following places in Scotland :— 
(1) in the Forth, above Queensferry ; (2) at the mouth of the 
Peffer Burn, near Aberlady ; (3) in an old brick-field frequently 
overflowed by the sea, near Dunbar; (4) in pools at the mouth of 
the River Alness, Ross-shire—all on the East Coast; and (5) on 
the West Coast. at Cumbrae, Firth of Clvde. At all these. places ~ 
the water is more or less brackish, and I know of only one other 
record of its occurrence in Britain in a purely fresh-water locality, 
viz., at Higham Park, Essex, where it was obtained by Mr. D. J. 
Scourfield, London. Though the occurrence of Hurytemora clausi 
in fresh water is rare in Britain, it seems to be otherwise on the 
;
