Read July iz.f" g “'HE famous foffiJ, which Dr. Lyttcl- 
* 75 3 ‘ A. ton Chew’d to the Royal Society fome 
time ago from Dudley in Staffordihire, and which is 
engraved and deferibed in N° 4.96 of the PranJ'aPtions y 
caufed many arguments to what clafs of animals it 
belonged, hr. Pococke afterwards produced two or 
three fpecimens of it extended, which proved it of 
t ie crultaceous tril e of animals. But none of his faid 
fpecimens being very fair, 1 have taken the liberty to 
lend you a very fair fpecimen of the faid foil'll ex- 
tended, fent me lad week from the iron mines at 
Colnbrookdale in Shropihire, and which ablolutely 
determines me to pronounce it to be the remains of a r 
crudaceous animal, of that kind called Pediculi ma- 
rini , which are fealed all round, and can at will roil 
themfelves up: And this particular kind (not to my 
knowlege yet difeover’d from fea) may be juflly 
Jynonymed Pedi cuius marinas major trilobos. 
Tho’ 1 heretofore thought it not deferibed by any 
Englidi author, yet I find it is deferibed and figured, 
tho badly, by our late member Mr. Edw. Lhuyd, 
in his Lithophylacium Britannicum lchnographia >
