174 The Hiftory of ANIMALS, 
This fpecies is found on the coafts of the North of England, but it is not common % 
it ufually adheres in clutters to wood that lies under water, 
P ollicipes albefcens pediculo cor pore breviori . 
The white Pollicipes, with the pedicle jhorter than the body . 
This is about three quarters of an inch in length ; and, in the Iargeft part, which is 
at the head of the pedicle, it is about half an inch in diameter: the body is of a py¬ 
ramidal form, and is fomewhat more than equal to the pedicle in length; it is com¬ 
pofed of a great number of oblong, pyramidal pieces of different diameters, and of a 
whitifh colour : the pedicle alfo is white, and is tbickeft at the top, whence it goes.all 
the way fmaller to the bafe. 
This fpecies is ufually formed in confiderable numbers together, and is not uncom-* 
mon on fome of our northern coatts. 
Pollicipes pediculo longiffmo dijlento . 
The P ollicipes ^ with a very long and diflended pedicle , 
This is a very lingular fpecies, and makes a very different figure from all the reft 5 
it’s pedicle is the moft confpicuous part of it: this is four inches long, and diftended to 
three quarters of an inch in diameter j it refembles a portion of a gut of fome animal, 
filled with a reddifh fluid : this is of equal, or nearly equal, diameter all the way, 
and is aflixed at one end to fome folid body, and at the other is terminated by a fhelly 
part, like the bodies of the former fpecies j this is about three quarters of an inch 
long, and is nearly equal in diameter to the pedicle at it’s bafe, but grows gradually 
fmaller to a point at the top: it appears fmall, in proportion to the pedicle, and is of 
a reddifh colour, and formed of a great number of valves. 
We meet with this on the Lancafhire coaft in great abundance ; the fluid, filling and 
diftending the pedicle, is of a gelatinous fubftance and infipid tafte. 
Pollicipes purpureus pediculo breviore dijlento . 
The purple Pollicipes , with ajhorter diftended pedicle. 
This is fomewhat like the preceding fpecies, but it is larger in the body, and fhorter 
and flenderer in the pedicle : the body or fhelly part is an inch long, and half an 
inch in diameter at the bafe : it is compofed of an irregular number of thin, pyrami¬ 
dal pieces of various fizes, and of a purplifh colour, variegated with white : the pedi¬ 
cle is two inches and a half long, and half an inch in diameter: it’s furface is fmooth, 
and it refembles, like the former, a thick membranous bag, filled with a reddifh flu¬ 
id : this is a thick, gelatinous matter, of an infipid tafte: the membrane, which in- 
clofes it, is tough and firm, but it is not very thick. 
We have this alfo on the Lancafhire coaft, and on fome other of our fhores $ it 
ufually is found fingly, not in clufters, but often many near one another. 
The other fpecies of the Pollicipes are, x. The oblong, yellow Pollicipes, with a 
fhort, flefhy pedicle. 2. The oblong, variegated Pollicipes, with a long conic, flefhy 
pedicle. 3. The white, long, and flender, pedicled Pollicipes. 4. The bluifh, fhort, 
and thick, diftended-pedicled Pollicipes. 5. The bluifh, longer and thicker dif¬ 
tended Pollicipes. 6. The flender pedicled, diftended, red and white Pollicipes. 
The fifh or animal, contained within the fhelly part of the Pollicipes, is very like 
that in the following genus, called by authors Conchas Anatifers; but the arms are 
longer and more deeply fringed, fo that they refemble feathers ftill more than thofe of 
that genus. The error of fuppofing birds to be produced out of thofe has alfo extend¬ 
ed itfelf to thefe, and they are called Goofe-fhells and Barnacle-fhells in the North of 
England, as well as the others. 
PENTELASMIS. 
E Pentelafmis is a genus of animals, compofed of a fhelly body, affixed to a 
flefhy and foft pedicle: the body is compofed of five valves, and the pedicle is 
fometimes fhort, and in other fpecies confiderably long.
