BRITISH FRESH-WATER ENTOMOSTRACA. 533 



D. bacillifer Koelbel [Brady (36)]. 



Only noted by Brady (36) from Loch Earn, Perthshire, so far 

 as I am aware. As the adult male was not seen, the record is 

 not so satisfactory as it might be. 



D. laciniatus Lilljeborg [8chmeil (44) ''Nachtrag"; T. & A. 



Scott (54)]. 



Confined to Scotland apparently, and a rare species even there. 

 Mr. J. Hewitt tells me, however, that it occurs pretty constantly 

 in Lewis. 



D. sanctipatricii Brady [Brady (36)]. 



If this is really distinct from I), laciniatus, it seems to be 

 peculiar to the British fauna. It has only been found as yet 

 by Professor Brady in Connemara (36). 



Eurytemora Giesbrecht. 



E. velox (Lilljeborg) [Schmeil (44) = E. lacinulata ; Brady (36) 

 := E. clausii\ 



Temora velox Brady (35). 



E. clausii Brady (36), Scott (20, 46, 47). 



E. lacinulata Scourfield (29). 

 Usually occurring in or near brackish water, but also thriving 

 in absolutely fresh water far inland, as at Higham Park, Essex, 

 the East London Waterworks reservoirs, little loch above Ruther- 

 glen (47), etc. 



E. affinis (Poppe) [Schmeil (44), Brady (36)]. 



Rarely, if ever, found far away from brackish water influence. 



Cyclopidae. 

 Cyclops 0. F. Mliller. 

 C. strenuus Fischer [Schmeil (44), Brady (36)]. 

 C. brevicaudatus and C. clausii Lubbock (42). 

 C. strenuus and C. yulchellus Brady (35). 

 C strenuus, C. ahyssorum, and C. vicinus Brady (36). 

 C. ewarti Brady (36), Scott (20, 46). ^ 

 Lilljeborg (40) admits no less than five variations of the strenuus 

 type to rank as species — viz., C. stre^iuus, C. scutifer, C. kolensis, 

 C. miniatus, and C. vicinus ; but it is doubtful whether these can 

 all be maintained. We certainly have some of these forms in 

 this country, but no separata records exist except for " vicinus,^' 

 The C. ewarti Brady is almost certainly an immature stage of 

 this species.
