__FORCETOC__
==Definition==
*''according to Hottinger (2006):''
'''FISTULOSE CHAMBERLET''' - (marginal chamberlet; peripheral chamberlet auct.); in agglutinated foraminifera the space produced through separation either peripherally or laterally of part of the chamber from the main chamber-lumen by a paraporous partition. May occur in species with either solid or paraporous walls. In the latter case, the partition is a continuation of the paraporous inner wall-layer beneath the outward turning outer, solid layer, the [[pavement]].
