THE CIRRHOPODA. 285 
stalk carries are protruded a number of curled, articulated appen- 
hages—the cirrii; these would be the fect of the animal, if it 
had any use for ambulacral organs, and hence the name of the 
order—Czrrhipedia. 
Cirrhi is derived from the Latin cérrhus, a curl or lock of hair, 
and is a term employed by naturalists in every kingdom of Nature _ 
to describe any curled filaments or appendages. Upon a close 
examination of the plate, fine hairs or cils will be seen growing out 
of the articulations of these cirrhi. When in repose these organs 
are curled up like the young fronds of a fern; but when the 
creature requires their use, they are extended and deployed on 
every side. They are seldom at rest, for the anatifera looks 
to its cirrhi for its sustenance. Like the rest of the fixed and 
sedentary animals it lives upon the animalcules and other minute 
existences which throng sea water ; and these are brought to it by 
currents which are formed by the regular and symmetrical move- 
ments of the cirrhi and their cils; but, strange to say, the mouth 
is not situated, as we might naturally suppose, at the entrance of 
the shell between the rows of cirrhi, but at the lower part of the 
shell, and the currents are directed so as to enter it. The mouth 
is furnished with mandibles and jaws like many of the crustacea. 
The name Azatifera literally signifies goose-bearer, and the 
appellation is due to a popular belief that these peculiar-looking 
creatures are the eggs of the bernicle goose, attached to a stem. 
Whether the idea was originated by an old writer, one Gerard, who 
enlightened his readers in the year 1636, or whether he only 
chronicled an existing opinion, we cannot say. He begins his 
account with the profession, “ What our eyes have seen and hands 
have touched we shall declare ;” and then he proceeds to describe 
the birth of a young bernicle goose from a ship-barnacle. “There 
is a small island in Lancashire called the Pile of Foulders, wherein 
are found broken pieces of old and bruised ships, some whereof 
have been cast thither by shipwracke, whereon is found certain 
spume or froth, that in time breedeth into certaine shells, in shape 
like those of the muskle, but sharper pointed, and of a whitish 
colour, one end whereof is fastened into the inside of the shell, even 
as the fish of oisters and muskles; the other end is made fast into
