is pyriform and thick walled ; the cirrus and vagina are beset with 

 bristles directed outwards ; the receptaculum seminis is fusiform ; the 

 ovary is large and double, and consists of radially placed club-shaped 

 tubes that do not anastomose and do not branch ; the vitellarium is

at the posterior border of the proglottids, the round shell gland in 

 front of it ; the uterus consists of a median trunk and fifteen to 



twenty-four non-ramified lateral branches 

 on each side ; the embryonal shell is thick 

 and has radial stripes it may be round 

 (31-2/4 to 33-8/4) or oval (39/4 by 33*8/4); 

 the spines of the oncospheres measure 

 7 /4 to 8 /4 in length (fig. 197). 



At present only two specimens are 

 known ; they came from a black soldier 

 from the vicinity of Lake Nyasa. The 

 cysticercus is unknown ; perhaps it lives 

 in the zebu, the flesh of which the Askaris 

 <After v. Linstow.) are in the habit of devouring uncooked.
