228 THE ANIMAL PARASITES OF MAN 



oncospheres of this species, from which subsequently the small 

 cysticerci originate in the intestinal wall (fig. 155) ; when fully 

 developed they fall into the intestinal lumen and become tape- 

 worms. The identity of the two forms has nevertheless been 

 disputed (Moniez, R. Blanchard, v. Linstow), though their near 

 relationship cannot be denied. Grassi gave mature segments of 

 Hymenolepis murina to six persons, but only one person evacuated 

 a tapeworm. This, however, proves nothing in a district where 

 Hymenolepis nana frequently occurs in man ; it was, moreover, 

 not possible to infect rats with segments of Hymenolepis nana (of 

 man). Accordingly this form may represent an independent species, 

 which, however, like Hymenolepis murina, also omits an inter- 

 mediary host. 



[Stiles and others state that the intermediate hosts of the 

 Hymenolepis are insects and Myriapoda. F. V. T.]
