EDITH M. PRATT, JB SC. 



found in the Forth, he thought that its habitat must be in ponds and 

 ditches which flow into the Forth. Since then it has been taken by 

 Scott in Loch Morar (Inverness-shire) and in Loch Moray. 



Only a few specimens of this species were taken in April and none 

 were taken in June. 



Cyclops ojfinis, Sars. 



Cyclops affinis, Brady, Brit. Copep. vol. i. p. 112, pi. xv. figs. 11—14, pi. xxiv. 

 B, figs. 10—15 ; id. Rev. Brit. Fresliw. Cyc. and Cal. p. 21, pi. viii. 



Brady says that this species seems to be of rare occurrence. Scott 

 records it from some of the Scottish lakes. It was taken in 

 Bassenthwaite in April, 1897, and has not since been taken. 



Cyclops Kaufmanni, Uljanin. (See note, p. 125.) 



Cyclops Kaufmanni, Brady, Brit. Copep. vol. i. p. 113, pi. xxiv. figs. 6— 12 ; 

 id. Rev. Brit. Freshw. Cyc. and Cal. p. 24, pi. ii. fig. hi. 



This species, although very limited from all accounts in its distribution, 

 was by far the most abundant species taken in April, 1898 ; in June it 

 was rare. 



Cyclops phaleratus, Koch. 



Cyclops phaleratus, Brady, British Copepoda, vol. i. p. 116. 



This species is not very common, though fairly widely distributed. 

 It has been taken in a few of the Scottish lakes by Scott, in Ireland 

 and North of England by Brady, but has not been recorded from the 

 English lakes. It was taken in Bassenthwaite in April, 1898, when it 

 was rather rare. No specimens were taken in June. 



Cyclops serrulatus, Fischer. ' 



Cyclops serrulatus, Brady, British Copepoda, vol. i. p. 109, pi. xxii. ; id. 

 Rev. Freshw. Cyc. and Cal. p. 18, pi. vii. fig. 1. 



This is the most common species of the genus. It occurs almost 

 universally over Britain, and has been recorded by almost all 

 continental writers. Specimens were only taken in Bassenthwaite in 

 June.
