anterior and ventral to that of the testis. The two halves are 
connected by a bridge which lies dorsal of the intestine, just 
behind the point where the dorsal cecum is given off. In 
this region are to be found the youngest ova, which pass from 
here right and left into the peripheral parts of the organ as 
they ripen. They appear to be budded off from the follicular 
epithelium which lines the whole of the organ. In the condi- 
tion of maximum development the ovary extends forward, 
obliterating the perivisceral space and filling the dotted area 
marked ov!. in fig. 4. The oviduct I have not been able to 
identify with certainty, but a structure which may be of that 
nature starts from the proximal edge of the ovary near the 
median bridge, and runs ventrally towards the region of the 
first thoracic appendage. It is probably visible with certainty 
only during the passage of an ovum; the vasa deferentia 
would have been similarly unrecognisable but for their being 
charged with spermatozoa for nearly their whole length. 
With regard to other structures in the body, a large mass 
of cells (gl. in figs. 4, 5) lies on each side of the intestine 
between the union of the stomodeeum and that of the hepatic 
diverticula with the alimentary canal. This gland, as it may be 
called, is not surrounded by any connective-tissue capsule or 
perivisceral epithelium, and consists of cells with large round 
nuclei, and strongly suggesting germinal cells in their histo- 
logical appearance. Against this possibility, however, argue 
the facts that they are not in contact with the ovary at any 
point, and that the youngest ova are to be found in the 
median bridge mentioned above as connecting the two halves 
of the ovary. No duct appeared to be connected with these 
“ slands,”’ and they are not continuous with each other below 
the intestine. A glandular mass in nearly the same position 
was recorded by Lacaze-Duthiers in his account of Laura. 
Starting in the oral cone, apparently in a loose network of 
connective tissue, a duct with clearly defined lumen runs back- 
wards to open at the base of the (first or) second appendage. 
As to the function or homology of this duct, I have no sug- 
gestion to offer at present.
