Abstract

The literature has been searched for records of single-transection regenerations which are presented in text and table. In the Lumbricidae, except in case of E. foetida, which had previously been considered, the information available is insufficient even to permit recognition of existence of major morphogenetic regions. I n C. lacuum alone have both seem to indicate specific variation in minor as well as major aspects of patterns of regenerative capacity. Results of one-level and simultaneous two-levels regeneration must be clearly distinguished. In view of the influence of a second regeneration taking place simultaneously, regenerative capacity in earthworms must be first determined from regenerations at single transections.
