Stalked cirripeds, with shell largely formed of scuta, terga, and carina; other parts may be added. Lepas aiiatifera* (fig. If4) is the goose barnacle, which owes common name to a medieeval myth which claimed that the Irish (or bernicle) ^1 goose developed from these animals. L. /'ascicu!aris,*(tig. 430), abundant floating on the eastern coast. Anelasma squalicola, a thin-skinned barnacle, is parasitic on sharks and forms a transition to the Rhizocephala. Order II. Balanidse. Sessile cirripeds with calcareous shell formed of carina, rostrum, and lateralia; scuta and terga forming the valves (fig. 437). BaJannshalanoides,* common on our coast. Coroniila diademata, attached to the skin ^'o- ^ faseinaarh* , , goose barnacle.
