ovaries of the female, and are not very unlike in general 
appearance to the ovaries of young females ; they differ 
however in being divided pretty deeply into several unequal 
lobes, the free extremities of which look towards each other. 
They send out each a very fine capillary tube or duct ; which, 
descending towards the rectum, is in one part of its passage 
convoluted on itself so as to resemble the human epididymis 
partially unravelled. 
The excretory duct above described terminates at the 
bottom of a thick pouch, which is situated between the rec- 
tum and the ventral integuments, and in form is not very 
unlike, though larger than the uterus, opening externally, as 
the uterus does, under the posterior margin of the last but 
one of the ventral segments of the abdomen. 
The interior mechanism of this pouch is extremely curi- 
ous ; for in the" upper part there is contained an apparatus 
somewhat in the shape of a coronet, of the colour and hard- 
ness of tortoise-shell : and at right angles to the centre of 
this there is fitted a similarly hard and horny substance, ( in 
shape resembling a short fiat club,) which descends towards 
the external opening of the pouch. 
Behind the pouch are situated one on each side, two oblong 
white bodies, which are twisted into three spiral coils, and 
then terminate by an inflected tube at the upper and back 
part of the pouch. These bodies evidently answer to the 
vesiculce seminales of insects in general : and resemble in 
their external character, and in their white pulpy contents, 
that oval body which is placed at the back of the uterus. 
There is also another pair of vesiculae seminales, as is fre- 
quently the case in insects, situated exteriorly to the former;
