A Contribution to a Knowledge of North American Fresh-Water Cyclopidae

Abstract

It is my purpose in this paper to make a first contribution to a revision of the nomenclature of this genus, such as is usually found necessary when, for the first time, the work of unaffiliated investigators is brought into careful comparison. I have embodied in this paper, not a complete revision of the American species of Cyclops, but only such results of my study on that group as have now been brought to a satisfactory conclusion.
