\Cir`ri*pe"di*a\, n. pl. [NL., fr. L. cirrus curl +
pes, pedis, foot.] (Zo["o]l.)
An order of Crustacea including the barnacles. When adult,
they have a calcareous shell composed of several pieces. From
the opening of the shell the animal throws out a group of
curved legs, looking like a delicate curl, whence the name of
the group. See {Anatifa}.
