This is one of the less common species of Cyclops. I have 

 only to add to the two localities given in the Ray Society Mono- 

 graph, one other, — Salt-marsh at Poole, Dorset, where it was 

 found by the Rev. Dr. Norman, F.R.S. Herrick notices the 

 species in his report on the Crustacea of Minnesota, but his 

 remarks appear to refer only to specimens taken at Leipzig. It 

 has been found by G. 0. Sars in Norway, by Claus, Rehberg, 

 and Schmeil in Germany, and by Fric in Bohemia.
