Since 1858 works on zoology and on the practice of medicine make 
mention of a tapeworm which 'Weinland described as Tcenia soliura 
var. oMetina. Opinions of authors have dilfered in regard to the 
exact status of the parasite in question, some writers considering 
that it represented a distinct species, others that it was a variety of 
Tcenia solium^ and still others, that it was a peculiar specimen of 
Tsenia. saginata. 
In a recent visit to Boston one of us found the original specimen, 
or rather all that seems to be left of it. in the AVarren Anatomical 
Museum, and through the courtesy of Doctor Mdiitney, curator of the 
museum, we have been able to reexamine this interesting material. 
In connection with_ a brief account of our rather unsatisfactory 
results it may be well to give a review of the history of the parasite 
in question, which now bears the U. S. P. H. & M. H. S. Xo. 9713. 
but which will be returned to the M^arren ^luseum.
