title: [Presence of a membrane system associated with the nucleus in the gamete of Pomacentrus leucostictus (teleostean fish)].
abstract: In the course of spermiogenesis of Pomacentrus leucostictus, a membraneous formation in the shape of a stack of saccules is applied to the nuclear envelope of the spermatid and persists into the spermatozoon stage. This formation occurs at the time the nuclear envelope of the spermatid forms, just at the end of the last maturation division.
