Abstract

In the course of examination of the intestinal contents of 21 specimens of Eurycea bislineata (Green) collected at Oxford, Mass., during the summer of 1939 a single newt was found of which the small intestine was heavily infested with an astomatous ciliate. Observations and measurements were made on the living organisms which were later killed with hot saturated aqueous mercuric chloride solution containing 2% of acetic acid. These specimens were ultimately stained, some with acid carmine, others with Ehrlich's acid haematoxylin with or without a counterstain of eosin.
