<i>Paranophrys marina</i> n. g., n. sp., a New Ciliate Associated with a Hydroid from the Northeast Pacific (Ciliata: Hymenostomatida)*

Abstract

SYNOPSIS. The ciliate, Paranophrys marina n. g., n. sp., is described from a marine hydroid, Plumularia sp., collected in the San Juan Archipelago, Washington. Morphological studies were made on specimens treated with the Chatton‐Lwoff silver impregnation technique. Particular attention is given to the infraciliature of the buccal apparatus and its importance in generic and familial assignment within the order HYMENOSTOMATIDA.
