rence, that the Shell being open a good Part 
of its Length, the Animal can thereby put 
out and draw in its Legs and Part of the 
Body when it pleafes.

fmall Globules, though not pearled as thofe 
of Land Infedts, but all contained in one In¬ 
tegument, wherein they appear to be in fome 
Degree moveable. The Animal has two of 
thefe Eyes: but as he always lies on one 
Side when placed in a Drop of Water to be 
examined by the Microfcope, no more than 
one can then be feen ; which induced Mr. 
Bradley to imagine it had only one Eye, and 
from thence to call it Mono cuius; but who¬ 
ever beholds the monffrous Pidture that

whether this Difference be owing to their Food, or fomo 
other Accident, or whether they are of different Species, I 
am unabk to determine.
