very hairy, efpecially at the Joints, and fo 
is the whole Body of the Animal, which oc-

tangled with the Dirt and Scurf of the Wa¬ 
ter, as to prevent its Figure from being tru¬ 
ly feen. 
The Divilions of the Body ^are each of 
them covered on their upper or back Part 
with a Scale or Cruft, extending beyond and 
hiding the Infertions of the Legs, which 
however are fhewn in N° 11, where the Ani¬ 
mal is turned on its Back. To the hinder- 
moft of thefe Diviftons the Tail is fixed, 
which is perhaps the moft remarkable Part 
of the Animal. Its Length is about three 
Times as much as that of the largeft Divifton 
of the Body $ its Breadth nearly equal to its 
Length, but tapering fuddenly towards the 
End, like the Tails of fome of the Beetle 
Kinds. From the back Part thereof, which 
is covered with a Shell 'or Cruft, arife two 
joined Branches, ftanding out at an Angle 
of about 45 Degrees to the Plane they rife 
from, each dividing again into two, and hav¬ 
ing Briftles like the Legs. The Ufe of thefe 
Branches is not yet difcovered. 
On the under or Belly Part are placed two 
Sets of Valves, riling up and falling down, 
alternately, in a perpendicular Direction: thefe 
may probably ferve for the Purpofe ofLungs, 
or as the moveable Coverings of the Gills of
