the nuclei of young egg-cells occurs at the bottom of the ovarian 
tubes (slightly swelled at their extremity). It is here that during 
a short time new eggs are produced. The vagina begins on the 
ventral side of the cirrus-pouch, and runs nearly in a straight line 
in the middle of the median field to join the oviduct. This canal 
dilates on two points of its course. The first widening is longish 
but not very considerable ; it is probably the receptaculum seminis, 
in which I could not find spermatoids,* also the structure is not 
the same that one generally finds in the other cestodes for the 
same organ. The second widening, very short, is not far from 
the point where the vagina rejoins the oviduct. The structure is 
the same as that of the vagina, but with a much more powerful 
longitudinal and circular musculature. The oviduct begins with 
a very well developed muscular funnel. This funnel is carpeted 
inside by an epithelium. From this organ the oviduct goes to 
meet the vagina, forming distinct circumvolutions (fig. 3). The 
oviduct is very wide, and carpeted by an epithelium, formed 
partly by columnar cells, out of which issue long cilia. From the 
point where the oviduct meets with the vagina, it becomes very 
narrow. It descends towards the shell-glands, and it is there 
that the vitelloduct throws itself into the oviduct. The small and 
slightly vitelligenous gland is the sexual gland which is situated 
before the ovary, as in all the Prostliecocotylce. From the shell- 
glands the oviduct leads in a straight line towards the dorsal side 
of the proglottis, where it opens into the uterus. The uterus is 
therefore situated on the dorsal side of the ovary. Its most con- 
siderable diameter is in the median line of the strobila ; it 
diminishes promptly laterally, where it passes between the longi- 
tudinal vessels of the excretory system. This conformation of the 
uterus is found in the segments where the sexual glands are still 
well developed. It is in this state that the uterus is carpeted by 
very high cells. When the uterus is distended with eggs, these 
cells suffer a granular degeneration of which we find the remains 
between the eggs. Are these granules used to nourish the eggs 
which are for a long time devoid of an envelope, even when they 
have already begun their segmentation? Or do they help the 
* We must say that our material consisted only of a few well-preserved 
fragments.
