Regeneration in the polychæt Chætopterus variopedatus

Abstract

1. Regeneration from different levels in the polychæt worm Chætopterus variopedatus has been studied.2. Regeneration can occur posteriorly from any segment, but anteriorly only from segment XIV forwards.3. Where regeneration occurs at all, given sufficient time, it will be complete, i.e. the original segments occupy in the new worm the relative position they originally occupied in the old worm.
