Two species of the genus Stephanochasmus have been found in the fishes examined for parasites at the station of the Carnegie Institution of Washington, situated on the island of Tortugas in the Gulf of Mexico. These are S. casus Linton and S. sentus Linton. The anatomy of these worms contains several novel and interesting features, and that of the first named will be described here in detail.
