Pseudocohnilembidae n. fam., a Hymenostome Ciliate Family Containing One Genus, Pseudocohnilembus n. g., with Three New Species*

Abstract
SYNOPSIS. A new family (Pseudocohnilembidae) of hymenostome ciliates is described based primarily upon the pattern of the buccal infraciliature which consists of two parallel rows of kinetosomes, nearly equal in length, representing the bases of two large membranes, and of argentophilic fibrils arranged in a more or less uniform design in the buccal cavity. A new genus (Pseudocohnilembus) with three species (one from Great Salt Lake, Utah, and two from the Atlantic coast) is described. These organisms bear superficial resemblance to Cohnilembus; an analysis of the buccal infraciliature of Pseudocohnilembus is presented, including a discussion of and comparison with that of Cohnilembus.
