Freshwater Copepoda 13 



Cyclops vicinus is new to America, but very likely will be shown to have the same 

 distribution as C. strenuus. 



Cyclops capillatus has before this only been known from Scandinavia. 



Taking the material as a whole, it is noticeable that it bears a striking 

 resemblance to the fauna of northern Europe and Asia, but that the two faunae 

 are not identical. Even in the circumpolar regions, the entomostracan faunae of 

 the eastern and western continents are differentiated from each other. This is 

 due, doubtless, to the lack of continuity in land surfaces, for, as shown elsewhere, 

 copepods are largely dependent on water carriage for their distribution, so that 

 fresh water copepods will be limited in their distribution to the opportunities 

 offered by contiguous bodies of fresh water.
