depressor muscle crests
In cirripeds (Balanomorpha), elevated denticles on interior of tergum near basicarinal angle for attachment of depressor muscles (crests may extend apically) [Moore and McCormick, 1969].
(Subclass Cirripedia):
Barnacle plate feature: on inner surface of tergum in unstalked form, elevated denticles or ridges near basicarinal angle. Serves as site of attachment of depressor muscle [Stachowitsch, 1992].
(Subclass Cirripedia):
Elevated denticles or ridges on inner surface of tergum near basicarinal angle for attachment of depressor muscles (balanomorph Cirripedia) [McLaughlin, 1980].
