term the JyVtf or m Appendages. Thefein the Male are 
. thick, hard, and void of Hair. Fig. the ij, C C, 
the t^o Jyliform Appendages. 
The Tail is continued, from the Trunk in a gra* ■ 
dual Decreafe of ’ its Dimenfion, and is covered by 
Plates, which extend themfelves but little below the 
Subftance of the Tail, and terminate in acute Angles, 
without any Ways diverging. Fig. the \ D D, 
the terminations of the Plates. 
It is to be obfervedjthat fometimes thefe Plates are edg* 
ed with Ihort and thin Hair, and fometimes have noHair. 
The Female on the other Hand, in the Place of the 
Tefticle has an Ovary, which, like the Tefticle, ex- 
tends itfelf from the Stomach to near one half of the 
Tail. From the Middle of the Ovary a Dud defcends to 
the Legs, which opens at a round Hole edged with 
Hair in the firftBone of the laft Leg but two: This is 
the Uterus. Fig. the A A, the Entrance into 
the t^o Vaginas. 
The two ProcelTes, which I have termed ISfympha- 
form^ in the Female make a more obtufe Angle at the 
Union of their Bafes ; are lefs hairy, and leave a Paf- 
fage, through which it is probable the Ova are emit- 
ted, to be affixed to the Appendages under the Tail.

The two ftyliform Appendages in the Female are 
foft, thin, and edged with long Hair. Fig. the 2^,

The Plates covering the Tail are extended much 
farther under the Tail than in the Males, befide 
which they diverge, in order to leave a greater Space 
for containing the Ova ; for the better Defence of which 
they terminate broad, and are edged with thick and 
long Hair. Fig. the id^ F F, the terminations of 
the Plates covering the tail. In
