Torelle, E. (1). Regeneration in Holothuria. In: Zoolog. 

 Anz. 35, p. 15 — 22. — Untersucht wurden 6 Dendrochiroten : 

 Cucumaria grubei, C. syricusiana, C. planci, Thyone briareus, 

 Th. fusus, Phyllophorus urna grubei, 3 Aspidochiroten : Holothm-ia 

 stellata, H. sp., H. impatiens, 3 Synaptidae: Synapta digitata, 

 S. inhaerens, S. hispida. — Die Resultate werden wie folgt zu- 

 sammengefaßt: „I.Parts of the body of species belonging to the 

 family Dendrochirota regenerate more readily than do species 

 observed belonging to the families Synaptidae and Aspidochirota. 

 — 2. Parts of the body posterior to the lantern regenerate more 

 readily than does the part containing the lantern. — 3. Animals 

 divided longitudinally do not survive the Operation. — 4. Animals 

 whose body-wall is cut open from oral to aboral end regenerate 

 new tissue to close the wound and replace missing parts auto- 

 tomously thrown off. — 5. The removal of a part of a radius is 

 apparently a more serious injury to Cucumaria grubei than the 

 removal of a part of the interradius. But it is not clear if this 

 is due to the removal of a part of the radial nerve or to the removal 

 of a part of the longitudinal muscle. — 6. The intestine usually 

 regenerates either from the cloaca, or from a part of the old inte- 

 stine near the cloaca. — 7. The new lantern is formed by a pro- 

 liferation of the material composing the bodywall. Buds from 

 the old radial nerves grow down into the lantern and ultimately 

 form the ringnerve."

 cia by sperm immersed in Solutions of Alcohol, Ether, Ammonium 

 Hydroxide or Ammonium Chloride. In: Bull. Wisconsin Nat. 

 Hist. Soc. 5 (1907), p. 112—124. — Durch die schon im Titel der 

 Arbeit angegebene Behandlung können inaktive Spermien aktiv 

 gemacht werden; bei den aktiven ist die Wirkung von der Dauer 

 der Behandlung abhängig. Schwache Lösungen wirken in längerer 

 Zeit ähnlich wie starke in kurzer Zeit.
