Mature specimens of trematodes were obtained from the gall bladder of 9 birds from among 48 Japanese tree sparrows, Passer montanus saturatus STEJNEGER which were captured during the period extending from November 30,1961 to July 10,1962 in Tottori. The infected birds are ones which were captured during the period from November 30 to December 5. It is to be noted that the rate of infection is high ; the infected birds each harbored 2 to 10 individuals of this parasite with 7 or more parasites in the most. The parasites were fixed in 70% alcohol under slide glass pressure, stained with DELAFIELD's hematoxylin and mounted in balsam. This trematode differs from the previously known species morphologically. Many genera and species of Dicrocoeliidae have been known, but only a few genera and species in Japan. In the cases of collection of parasites in small wild birds, it is needful to examine fully not only the intestine but other organs. So, here the authors wish to review a part of the systematics of the trematodes belonging to Family Dicrocoeliidae with a report of a new trematode.
