ResumoThe calanoid copepods discussed herein represent a small number of incompletely known, closely allied species for which three generic names have been proposed.'To this list are added two new species from collections made among the keys of the Dry Tortugas, Florida, by Mr. Clarence Shoemaker of the United States National Museumin the course of an amphipod survey of that region (Shoemaker, 1933(Shoemaker, , 1956)).The debris washed from rocks and corraline algae taken at very shallow depths of a few inches to a few feet has yielded not only amphipods but other Crustacea among which were many small copepods.These included mostly Harpacticoida and Cyclopoida characteristic of such a habitat, but some Calanoida were also present.Among these were adults of the two new species and a few subadult males of an unknown species that are herein assigned to the genus Ridgewayia.This rather unusual genus has been known since 1903 when Thompson and Scott described the female of R. typica from Ceylon.Since then, closely allied species have been described as the types of new genera without comment on their obvious relationship to Ridgewayra.
