- according to Hottinger (2006):
PASSAGE – the means of communication between adjacent compartments of the same chamber; it is an opening that may be sited below the frontal chamber wall (preseptal), after the septal wall (postseptal) as in alveolinids, or at the fusion between exoskeleton and endoskeleton, as in verbeekinids. In peneropliform to concentric architectures, the passages may be semiannular-annular, in a preseptal position, as in Sorites, or paired in lateral positions, separating exoskeleton from endoskeleton, as in Anchispirocyclina or Orbitopsella.
