SYNOPSIS. Comparison of dimensional and other morphological details of adult suctorians recovered from the gills of five genera of fish from five widely separated localities in North America indicates that the practice of identifying a distinct suctorian species based upon the species of fish with which it is symbiotic is unfounded. Conversely, identification of suctorian species based on their adult morphology alone under certain conditions is justified. An emended diagnosis of Trichophyra piscium Bütschli, 1889, is presented. The pigment in T. piscium recovered from Oncorhynchus nerka (sockeye salmon) was characterized as melanin and its significance to the suctorians is discussed.
