A closely allied species occurs in horses and asses in many parts of Africa. Watsonius watsoni (Fig. 79) is a related species, also reddish brown in color, found in the small intestine of West African negroes. A closely related species, Paramphistomum cervi, is found in the stomach of sheep and cattle in Egypt and has a life history almost identical with that of the sheep liver fluke. This or a very similar species occurs in the stomach of cattle in the United States. Several large flukes of the genus Fasciolopsis n • ii ™ i 7 . sucker (v. s.).

It normally inhabits the small intestine of the hog but occasionally parasitizes man. The larval stages are said to encyst in shrimps, but Leiper had no success in in- fecting hogs with the cysts which he found in shrimps. Fig. 79. Watsonius watsoni.
