Argentophilic structures of the miracidium of Echinostoma trivolvis were described from 80 specimens reared from material originally collected in eastern Pennsylvania, U.S.A. Miracidia were impregnated with 0.5% aqueous silver nitrate solution. The miracidium has 18 epidermal plates arranged in 4 rows of 6 + 6 + 4 + 2 = 18. Up to 20 papillalike structures on the terebratorium were arranged along 3 axes and in 5 groups. A single papilla was located at the base of each of the 6 epidermal plates of the first row. The eyespots were located posterior to the first row of plates and 2 excretory pores were located anterior to the last row of plates.
从最初在美国宾夕法尼亚州东部采集的材料中培育出的80个三歧棘口吸虫毛蚴标本，描述了其嗜银结构。毛蚴用0.5%的硝酸银水溶液浸染。毛蚴有18块表皮板，排列成4排，即6 + 6 + 4 + 2 = 18。穿刺器上多达20个乳头状结构沿3个轴排列成5组。单个乳头位于第一排6块表皮板每块的基部。眼点位于第一排板的后方，2个排泄孔位于最后一排板的前方。
