Abstract
The "throbbing" brood-sacs of the fluke Leucochloridium which are sometimes found in the tenacles of snails belonging to the genus Succinea are indeed spectacular. Two examples of the sporocysts were found in a collection of eleven Succinea retusa taken on July 29, 1947, at the hanging bog on the west shore of Silver Lake, Dickinson County, Iowa. Only one sporocyst included a mature brood-sac, this was about 5.0 X 1.5 mm. with a long (20 mm.) thin stalk connecting it to the rest of the sporocyst. Its distal end was capped with red-brown; immediately below this a narrow creamwhite band followed by another broad band of red-brown, then a broad band of cream-white, finally another band of red-brown which shades into the cream-white of the remaining half of the brood-sac. The brood-sac contained numerous metacercariae. Apparently this is similar to the red-brown brood-sac described by Woodhead (1935).
