This trematode, know heretofore only from W. S. Nickerson's one finding in the intestine of the sheepshead, Aplodinotus grunniens, from the Lake Pepin region of the upper Mississippi, occurs not infrequently in a restricted portion of the intestine of the clam, Lampsilis luteola, in West Lake Okoboji. In this same lake it has been taken sparingly from the sheepshead also, and as clams are included in the fish's diet, direct transfer by this means is suggested.
