arising, as in //. i/imti, from jx>lar tulx-rcles on the inner 

 wall. There is, however, too much divergence in the seg- 

 ments to permit the identification with H. nana, and the 

 writer is disinclined to regard the peculiarity of the ova 

 noted as sufficient basis for separating these specimens as 

 a novel species.

 of man has been met in the work of the laboratory three times 

 within the past few years. Dr. William Pepper (Path. Mus., 

 170) obtained, after recognition of the ova in the stool and 

 the administration of an anthelmintic, an entire strobile in 

 the dejecta of a Norwegian sailor in the University Hospital 

 in KM)."). I )r. H. N. Willson, in 1<M)(>, referred to the laboratory 

 a portion of a strobile of the parasite (Path. Hist., 852) which 

 he had obtained after administration of an anthelmintic 

 from the feees of a young male Polish student in the University 

 of Pennsylvania; and in the spring of 1907, Dr. C. LeR. 

 (Jriswold, then a fourth-year medical student, obtained a 

 meter or more of the strobile of the same species of tapeworm 

 i I'ath. Hist., 1822) from another student. The host in this 

 last instance was an American, but had spent his previous 

 summer vacation in European travel; and as all the symp- 

 toms suggestive of parasitism had followed this European 

 sojourn, it is possible that this, too, was an instance of the 

 importation of the worm. 



A number of fragments of what the writer believes to be 

 the same parasite (Path. Hist., 1454) were found in the large 

 intestine of a gray fox, Canis cinereo argentatus (P. Z. G. 

 Lab., 1001). The head was not found in this case. The 

 anatomy of the links corresponds closely with the recognized 

 structure of proglottides from man, but the ova are distinctly 

 smaller than those from the worm from human subjects 

 (averaging 0.054 mm. long and 0.030 mm. transversely) and 

 are slightly more pointed toward the operculated end. . An
