Definitions

Compartment plate of cirripeds located on either side of carina, with radii on cardinal side and alae on rostral side.
(syn. latus (cardinal)) [Moore and McCormick, 1969]
Balanus trigonus: apical view; left lateral view; and operculum, body, and branchiae. [Anderson, 1980]
(Taxon-specific: Subclass Cirripedia) (Figure only.) [Anderson, 1980]
Balanus trigonus: wall plates, exploded; and interior of operculum. [Anderson, 1980]
(Taxon-specific: Subclass Cirripedia) (Figure only.) [Anderson, 1980]
(Taxon-specific: Subclass Cirripedia) Barnacle shell plate: in unstalked form, paired posterolateral plate, one between carina and each lateral plate. Consists of median paries with radius on one (carinal) side, ala on other (lateral) side.
(syn. carinolatus) [Stachowitsch, 1992]
(Taxon-specific: Subclass Cirripedia) One of pair of compartmental plates typically overlapping carina on each side, with radius on carinal side and ala on lateral side, sometimes absent; homologous with lepadomorph carinal latus (balanomorph Cirripedia). [McLaughlin, 1980]
