contact with the anteriorly situated ovary. It is impossible to 
say where ovary ends and “ uterus” begins. There is nothing in 
these facts to forbid the assumption that the eggs leave the ovary 
and migrate directly into the parenchyma, not reaching it wid 
a uterus. 
Towards the end of the body the uterine cavities, if they be 
such, have completely disappeared, and the embryos (text-fig. 3) 
are more or less evenly scattered through the parenchyma. They 
even get to be found in the cortical parenchyma, though by no 
means numerously. It is not infrequent among tapeworms for

the ripe embryos to lie also in the cortical parenchyma; and 
in an ally of the present species, viz. Linstowia brasiliensis, the 
eggs stray thither*. The ripe embryos of the present species 
are hexacanth, as is usual; each appears to be wrapped in three 
shells—unless the outermost membrane, which is more stainable 
by hematoxylin, be regarded as belonging to the maternal tissues. 
The spaces of the parenchyma, in one of which each embryo hes, 
fit the shells fairly accurately, and show no signs of being 
independent cavities lined by an epithelium.
