confifi: of five pieces. This, from its appearance, I 
have called the Britifh Channel Penknife, to diftin- 
guifh it from the other. t 
Fig. 4. is a fpecies of Barnacle called Pouflepieds 
by the French, and defcribed by Rondeletius as com r 
monly found adhering to rocks on the coaft of Brit- 
tany. He fays the people there boil and eat the Item, 
which is firfl: of a moule-colour, and afterwards be^ 
comes red like our prawns. There are many heads, 
that arife out of one Item, each of which confifts of 
two {hells, in which are the fame parts of the ani- 
mal as in the other fpecies. This I have called the 
Cornucopia Barnacle. Some of the fhells of this 
Barnacle were drawn from a fpecimen in the Britifh 
Mufeum. This Lepas is the Mitella of Linnaeus. 
Fig. y. and 6. are the Barnacles called Conchas 
Anatiferae : thefe are the forts fo well known to 
Tailors, and formerly fuppofed to produce a large 
fpecies of duck called a Barnacle. Thefe confifi: of 
five fhells. The tube, that fupports one of thefe 
kinds, branches out like fome fpecies of corallines, 
bearing a fhelled animal at the end of each branch. 
They are generally found adhering to pieces of wood 
in the fea, and moft fhips have fome of them flick- 
ing to their bottoms. Thofe of the fouthern and 
warmer climates are generally of a larger kind than 
ihofe of the colder and more northern climates. 
The next divifion of thefe animals is, thofe that 
adhere by the bafe of their {hells, having no hems. 
Here I muft obferve, that the bottoms of the fe- 
veral fpecies of this divifion conform in fhape to the 
fubftances they adhere to, or grafp them in fuch a
