the termination of the Plates covering the tall on 
the left Side, 
Thefe Plates diverged likewife on the right Side, as 
in the Females, but not on the left Side, as in the Males. 
Fig. the 4th^ A, the diverging of the Plates onthe 
right Side ; B, the Plates no fVays diverging. 
Upon removing Part of the great Shell, I found the 
internal Parts of Generation in both Sexes exadly 
correfponding to thofe externally deferibed. 
In the right Side adjacent to the Heart, the Oviduct 
was regularly difpofed, it was full of Ova^ and fent 
ofF its OviduB or Uterus.^ to the antepenultimate Leg. 
Fig. the ^th^ F, the Ovary ; G, the Ovidudl or Ute- 
rus leading to the antepenultimate Leg. 
In the left Side the 1 efticle was rightly difpofed as 
to its Form, Subftance, and Situation, Part of which 
I was obliged to remove, in Order to (hew the PeniSy 
which terminated as in all Males, at the Tubercle in the 
firft Joint of the laft Leg. Fig, the jighy E, the Penis • 
I, Pa7't of the tejticle unremoved. 
I had fome Thoughts of removing fo much of the 
great Shell as was neceffary to fhew the Courfe and 
Terminations of the Uterus and Penisy at their proper 
Orifices. But confidering that by that Means the Tail 
would tooeafily feparate from the Trunk, and the Ap- 
pearances of the other Marks be rendered lefs obvious,’ 
I chofe only to lay them open at the Back, believing 
that to be fufHciently fatisfadory to thofe who under- 
ftand the Structure of that Animal, I have (teeped it 
in three different Spirits, and carefully difpofed it in a 
Glafs, which I have flopped in the beft Manner I can, 
that it may remain in the Repofitory, as an undeniable 
Proof of fo remarkable a Fad.
