frequent occurrence in Loch Dow and in Black Loch, 

 Kinross-shire. This is the first record of it from both of 

 these counties. 



Notoclromas monacha (Miiller) was also common in Loch 

 Fitty and in pools at Luffness Links. This species does not 

 appear to have been previously recorded for the east of 

 Scotland ; it is easily distinguished by its peculiar form and 

 colour (being black, or nearly so). 



Candona acuminata (Fischer). Loch Fitty is the only one 

 of the nine localities here represented where this Candona 

 was obtained, though I have it from other districts. It is one 

 of the rarer British species, and has been observed in only a 

 few places in Scotland. 



? Candona hyalina, Brady and Eobertson. A Candona 

 which seems to belong to the species named was of frequent 

 occurrence in Loch Fitty ; it was also obtained, though not 

 common, in Lurg Loch and Dow Loch. I found by dissect- 

 ing the animal that it differed especially in the length of the 

 joints of the antennules and antennae from either C. kingsleii 

 or C. fahceformis ; the form of the shell also differs from both 

 these species. The dorsal margin slopes upward similarly 

 from each end, and forms a distinct central ridge. All the 

 specimens examined were females. Though only the east 

 end of Loch Fitty was searched, no fewer than eighteen 

 species of Ostracoda were obtained. 



Gypris ohliqua, Brady. This is a rare species in Scotland, 

 and hitherto appears to have been observed in only four 

 localities, viz., Lewis, Isle of Skye, Bute, and Cumbrae, 

 which are all on the west coast. I am now able to add two, 

 though closely adjoining, localities toward the east coast for 

 this Cypris — Dow Loch and Lurg Loch in Kinross-shire. It 

 is a very neat and distinct species. The colour of the 

 specimens for these two lochs is a rich chocolate-brown, 

 similar to those recorded by Mr Eobertson of Millport from 

 the Isle of Man, while those from a lochan or tarn on the 

 hillside above Millport, Cumbrae, are bright green. 



Candona euplectella, Robertson. A reference to this species, 

 which when clean and in good form excels in beauty all 

 other European Ostracoda, will conclude my remarks on the
