Abstract: The recovery of 51 specimens of Trichuris skrjabini (Baskakov, 1924) from sheep raised at the Meat Animal Research Center, Clay Center, Nebraska, increased the number of species of Trichuris reported from domestic ruminants in the United States to 3: T. ovis (Abildgaard, 1795), T. discolor (von Linstow, 1906), and T. skrjabini. Trichuris skrjabini was first described from Camelus dromedarius and C. bactrianus in Turkestan, USSR, by Baskakov in 1924. It has never been recorded heretofore in the Western Hemisphere, although it has been reported from many different ruminants in Asia and Europe. Trichuris discolor was first described by von Linstow in 1906 from Bos indicus, in Colombo, Ceylon; it has since been reported throughout the world. Since previous descriptions are incomplete and differ from one another, T. skrjabini and T. discolor are here redescribed and compared with specimens of T. ovis, also from the United States, as an aid to their identification. It is suggested that T. skrjabini may have been introduced into the United States in 1856 with camels imported by the U. S. Army for possible use as beasts of burden in the deserts of the Southwest. This report present redescriptions of the distinctive features and body measurements of adult male and female T. discolor from cattle in Louisiana and Mississipi, and T. skrjabini from Nebrasca sheep. Comparisons of body measurements are made with previously published descriptions of these two species and with T. ovis (Abildgaard, 1795), the other species of Trichuris reported from domestic ruminants in the United States.
