REGENERATION IN PEROPHORA VIRIDIS

ABRAHAM GOLDIN 1

1 Department of Zoology, Columbia University, and the Marine Biological Laboratory, Woods Hole, Mass.

1. Stolons of Perophora, isolated from between two zooids, regenerate at the cut ends but do not necessarily maintain their original distal-proximal polarity relationships.

2. Stolon tips, after isolation, maintain their distal-proximal polarity, the distal end displaying dominance.

3. The inner stolonic material, when expressed from the tunic, may grow and regenerate buds at any point along its axis.

4. Regeneration is hindered at ligatured ends of stolons.

5. When stolon-zooid systems are isolated and maintained under optimum conditions, the entire stolon-zooid system may grow.

6. The theoretical implications of the results of these experiments are discussed.
