Notes on a Synall Collection of Fresh- Water Ostracoda. 315 



At present it is not known to occur in any other locality in 

 the British Islands, unless the Cypris (jihhosa recorded by Dr 

 Baird from a ditch in Surrey more than fifty years ago be the 

 same species. I have obtained it in considerable abundance 

 in one particular part of the loch. Comparatively it is a 

 moderately large Ostracod, of a yellowish colour. It is 

 much compressed laterally, but has the dorsal margin pro- 

 minently arched. 



Erpetocypris olivacea, Brady and Norman, from Dudding- 

 ston Loch, is as yet a comparatively rare species, though in 

 localities where it does occur it may be fairly plentiful. 

 Till lately Duddingston Loch was the only Scotch locality 

 where it had been observed. I am now able to exhibit 

 specimens from Kinghorn Loch, Fifeshire, and from Black 

 Loch, Kinross- shire. 



Erpetocypris tiimefacta (Brady and Eobertson). This 

 species, which does not appear to have previously been 

 recorded from anywhere near Edinburgh, is exhibited in this 

 collection from Duddingston Loch, pools at Luffness Links, 

 Loch Eitty (Fifeshire), and Black Loch (Kinross-shire), and 

 is of frequent occurrence in all these localities. 



Candoiia rostrata, Brady and Norman, not previously 

 recorded from the Edinburgh district, has been obtained from 

 Duddingston Loch, Loch Fitty (Fifeshire), Lurg Loch and 

 Black Loch (Kinross-shire). It seems to me that this will 

 ultimately be found to be a generally distributed species. 



Cypris piibera, O. F. Muller. I obtained this fine species 

 at Kinghorn Loch in considerable abundance. I have also 

 seen specimens from Kilconquhar Loch, near Largo. It has 

 been previously recorded from Duddingston Loch (a young 

 specimen from this loch is also on one of the slides 

 exhibited), the Town Loch near Dunfermline, and Lin- 

 lithgow Loch. Its distribution in Scotland seems to be 

 confined to the middle and eastern counties, but perhaps 

 when the invertebrate fauna of these islands becomes more 

 thoroughly worked up, C. picbcra may be found to have a 

 wider range. 



Cyclocypris glohosa (G. 0. Sars) was one of the more 

 common species in Loch Fitty, Fifeshire; it was also of
