The specific identification of a megalurous cercaria found in the snail Oxytrema plicifera was accomplished by completing the life cycle in the laboratory. This species is compared with the eastern Philophthalmus megalurus and P. gralli with which it was once confused. The eggs, miracidia, and rediae of the Oregon species were found to be similar to those of the above species. The body and organ sizes and sucker ratios for the cercariae and adult stages obviously indicate that the Oregon species is Philophthalmus megalurus.
