Les septa se développent au dessous des tissus mous du fond et de la paroi des 

 loges sous-tentaculaires, ils ne sont pas le résultat de la calcification des mésen- 

 téroïdes. Le très jeune polypier est cylindrique; arrivé à une certaine hauteur 

 (2 — 3 mm) l'un des tentacules, sa loge et le bord correspondant du peristome 

 s'incline et arrive en contact de la surface sur laquelle le polype s'est fixé. Une 

 adhérence nouvelle s'établit et le calice devient ovale.

The ova take their origin in the Endoderm and pass into the Ectoderm. They 

 do not always rest upon the supporting lamella. The spermatozoa are ectodermal 

 in origin. The author considers Hydractinia as degenerate and the gonophore 

 as a retrograded umbrella. The ova of Hydractinia are laid at a definite period of 

 the day. Segmentation is total and equal. By breaking down of endoderm cells 

 the coelenteric cavity arises.

The most noticeable peculiarity in the development of this form is the formation 

 of the entocodon or »Glockenkern« as a hollow (not a solid) invagination, and the 

 absence of any trace of manubrium and mouth. Like in the Narcomedusae the 

 gonads are developed on the walls of the manubrium and the marginal sense- 

 organs have an endodermal axis. But Limnocnida has hollow tentacles. On the 

 possible origin of marine forms in the lake Tanganyika.
