    preserved, so that a number of points I have been obliged to leave for further study. The present study, however, reduces the known leporine forms (Andrya and Bertia excepted) to a comparatively satisfactory system. It must be held in mind that every classification proposed for the Cestoda for some years to come is experimental and provisional, for helminthology is not yet so far advanced that we can tell with any degree of certainty what characters or combinations of characters should be looked upon as of family, subfamily, generic, subgeneric, specific, and varietal value, and what characters should be attributed to host-influence. Bate of American species.—“Notes on Parasites—-38: Preliminary note to CA Revision of the Adult Leporine Cestodes,’V1 established August 28, 1895, as the date of the new specific names used in this paper. Important notice to helminthologists.—Owing to the fact that Hassall and I have been using material from different helminthological collec- tions, more particularly from the collection of the Bureau of Animal Industry, collection of the United States National Museum, collection of Hassall, collection of Stiles, and collection of Leidy (University of Pennsylvania) bearing parallel current numbers, some confusion has arisen because the same number sometimes appears in all five collec- tions. These five collections were commenced independently, and as their union (temporary or permanent) was not foreseen, this duplication of numbers could not be avoided. To avoid such confusion in the future as far as possible, the collection of the Bureau of Animal Industry and collection of Stiles will be cov- ered into the United States National Museum, and receive the current numbers of the helminthological collection of the Museum. The numbers which have been published will not be affected by this change, so far as can now be foreseen. The numbers of a few of the specimens which have been distributed, however, will in all probability be changed. Records of these specimens have been kept in the Zoolog- ical Laboratory, Bureau of Animal Industry, and new labels bearing the new numbers will be written and mailed to specialists and museums possessing such specimens as are affected by the renumbering of the collections. The Leidy collection, as I have stated in another publication, is depos- ited with me only temporarily and will be eventually returned to the University of Pennsylvania. Duplicates, however, will be kept with the United States National Museum. Family T^ENIIDZE.
