Land and Fresh-Water Crustacea around Edinburgh. 55 
with the dam, I found the following species of Ostracoda, 
and one or two rare things belonging to another group :— 
Cypria ophthalmica (Jurine). Cypridopsis villosa (Jurine). 
Cypria serena (Koch). Candona candida (O. F. Miiller). 
Erpetocypris reptans (Baird). Candona kingsletvi, Brady and Robert- 
Erpetocypris twmefacta (Brady and son. 
Robertson). Candona acuminata (Fischer), 
Cypridopsis vidua (O. F. Miller), Ilyocypris gibba (Ramdohr). 
In company with an old friend—Mr Thomas Struthers— 
who is thoroughly familiar with the district around Edin- 
burgh, I examined some pools near GOREBRIDGE in December 
1889, and obtained the following species :— 
Cypria ophthalmica (Jurine). Candona candida (O. F. Miller). 
Erpetocypris tumefacta (Brady and Candona pubescens (Koch). 
Robertson). Candona kingsleti, Brady and Robert- 
Potamocypris fulva, Brady. son. 
At SEAFIELD, near Dunbar, there is an old disused brick- 
field in which are several pools of water. The brickfield is 
close to the sea-shore, so that during high tides the sea flows 
into the pools and causes the water to become brackish. The 
little shrimp-like Crustaceans, Mysis vulgaris and Palemonetes 
varians, frequent some of the pools. Being desirous to learn 
about the Ostracod fauna of these pools, I got my friend 
Mr Jamieson, Assistant Naturalist to the Fishery Board, to 
collect some material and send it to me. I also, in company 
with him, made a personal examination of the pools. The 
following species of Ostracoda were obtained :— 
Cypris prasina, Fischer. Candona candida (O. F. Miiller). 
Erpetocypris twmefacta (Brady and Candona pubescens (Koch). 
Robertson). Ilyocypris gibba (Ramdohr). 
Cypridopsis aculeata, Lilljeborg. Cytheridea torosa (Jones). 
Potamocypris fulva, Brady. 
The brackish-water pools at the mouth of the COCKLEMILL 
Burn, near Largo, Fifeshire, were examined, and yielded the 
following species :— 
Cypria ophthalmica (Jurine). Candona lactea, Baird. 
Cypris (2) virens (Jurine). Cytheridea torosa (Jones). 
Potamocypris fulva, Brady. 
Along with the species enumerated from these two brackish- 
water localities, there were several others more nearly allied
