teristic hook of H. peromysci n. sp., its eggs (av. .072 by .060 mm) are larger than those of H. straminea (.063 mm diam.), H. nana (.050-.053 by .037-.041 mm), and R. meriones (.048-.055 by .040-.042 mm). Of the three related species only H. nana is reported from North America.

NATURAL INTERMEDIATE HosTS Insects, principally beetles were collected for several months from the study

area and examined for the presence of cysticercoids. Fleas taken from host ani- mals were found to be negative as were carabid beetles Pterostichus californicus DeJean collected from the field. The infected beetles were all tenebrionids which are commonly called "stink beetles" because of their method of defense (see Eisner & Meinwald, 1966). By rearing the cysticercoids in hamsters (see Materials and Methods) and identifying the subsequent adult tapeworms, it was determined that Eleodes armata LeConte and E. dentipes Eschscholtz were inter- mediate hosts for Hymenolepis peromysci n. sp. Similarly E. longicollis LeConte and Stenomorpha tularensis Casey were found to harbor cysticercoids of H. citelli.

IN MEMORIAM WILLIAM W. CORT (1887-1971)

In the passing of Dr. W. W. Cort on 21 August 1971, the world lost one of America's most outstanding parasitologists, not only in his proliferation of papers (especially in helminthology) of highest quality but also in his influence on the development of modern parasitology in America during the past century.

Among the many societies to which Dr. Cort belonged and in which he held officerships was the American Microscopical Society. Long an active member, he served as President in 1937. Much of his professional career was spent as a faculty member at Johns Hopkins University, with summers of research and teaching at the University of Michigan Biological Station. In these two locations he served directly as doctoral advisor for some 50 graduate students in parasitology, many of whom continued in fields requiring microscopy as an indispensable tool in their research.

This notice is brief; but a full account is appearing elsewhere (Foster & Otto, Proc. Helminth. Soc. Wash., Jan. 1972). All members of our Society will be sad- dened by the knowledge of the passing of this great man.

--JOHN O. CORLISS
