Extract

1. A new variety of the trematode Harmostomum opisthotrias is reported from the North American opossum.

2. Body proportions in this genus are more constant than linear dimensions and are, therefore, considered more desirable as a basis for taxonomic distinctions.

3. The occurrence of this parasite in a host with a range as limited and a phylogenetic position as critical as that of the opossums suggests the possibility of valuable information to be obtained through host-parasite relationship studies in this group. Investigators who are working with this material should keep the problem in mind.
