Abstract
During the spring semesters of 1955 and 1956, while the writer was under the supervision of Dr. A. E. Noble, a preliminary survey was initiated on parasites in local fishes, amphibians, and reptiles occurring in the vicinity of Stockton, California. The collection of specimens in this survey included sixteen green sunfish, Lepomis cyanella, and two bluegills, L. macrochirus. Larval trematodes recovered from the heart and liver of these specimens belonged to the family Diplostomatidae Poirier (1886) which is characterized by a conspicuous constriction separating the fore and hind-bodies. The leaf-like forebody with the lateral borders converging ventrally to form a spoon-like concavity containing the holdfast organ and acetabulum, a hind-body enclosing the reproductive organs, and a bursa copulatrix at the posterior and are diagnostic characteristics.
