Notes
The infraciliature of 11 species of the hypotrich ciliate Euplotes was studied with the Chatton-Lwoff silver impregnation technique. Particular attention was given to the number of dorsolateral kineties, the interkinetal network, the number and spatial arrangement of the ventral cirri, the morphology of the peristome and its bordering adoral zone of membranelles (AZM), and the shape of the macronucleus and the position of its replication bands during DNA synthesis. The following characteristics constitute a trustworthy basis for separation of species within the genus Euplotes: (1) the pattern of the dorsal interkinetal network; (2) the number of dorsolateral kineties; (3) the shape of the AZM and the number of membranelles composing it; (4) the number, spatial arrangement, and distribution of the ventral cirri; (5) the shape of the interphase macronucleus. Four new species of Euplotes are described, three from intertidal pools in Nassau, Bahama Islands (E. indentatus, E. magnicirratus, E. polycarinatus n. spp.) and one from a fresh-waer habitat in Madison, Wisconsin (E. octocarinatus n. sp.).
