Color often red or reddish during life, especially about the apertures. Branchial sac usually with more than four large folds on each side, stigmata usually straight (spiral in a few cases); stomach elongate, tapering into the intestine, and bearing a hepatic organ of small tubes. Gonads few (usually but one on each side), elongate, hermaphroditic, the left commonly in, or partly in, the intestinal loop. No renal sac." (Van Name 1945: 218)
