__FORCETOC__
==Definition==
*''according to Hottinger (2006):''
'''INTRASEPTAL INTERLOCULAR SPACE''' - the [[interlocular space]] formed between the posterior [[bilamellar wall]] of a [[chamber]] and the distal bilamellar wall of the preceding chamber, as a result of a deeply sunken suture. Intraseptal spaces may be open to the exterior along their margins either continuously or through openings between points of marginal adherence of consecutive lateral chamber walls.
