A. anneclens, like A. inequiannulata, is a small blood-sucking glossiphonid, the type of which is9 mm. long, 2 mm. wide, and about 1 mm. high. The general form is nmch like that of Glossiphoimifusca but considerably more slender; the body is strongly convex above, flat below, the region of thegastric caca about half round; the head end, with the sucker and mouth, have the typical glossi-phonid form; and the thick, prominent, hemispherical caudal sucker measures mm. in diameter.
