Numerous trichomonad flagelletes from the intestines or various birds have been described; but as fas as the writer has been able to discover, none from the intestine of the coot, Fulica americana. Martin and Robertson (1911) described Trichomones eberthi and T. gallinerum from the caecum of fowls; Kotlan (1923) described Tetratrichomonas avatis from the caecum of ducks; Tyzzer (1930) described flagellates from the ruffed grouse.
However, the species described by the above authors are quite different from Trichomonas to be described in this paper. This organism is definitely a member of the genus Trichomonas since it possesses the distinguishing characteristics of the group: four free anterior flagella, an undulating membrane, a chromatic basal rod, an axostyle, a trailing or posterior flagellum, and an anteriorly located nucleus. This flagellate, however, is unusual in possessing a long narrow rod-shaped parabasal body or rod which is a constant character.
