Esperellaßbrexilis, Tedania Brucei , Te Janio7ie foetida nn. S'p'p . — The Olyn- 

 thus is the common ancestor of the group. The outgrowth of radial tubes gave 

 rise to the Sycon type. The growth of the mesoderm and development of new 

 endodermic diverticula , coupled with the metamorphosis of radial tubes into fla- 

 gellated chambers, produced the Leucons. The efi"erent system is entirely endo- 

 dermic, the afferent system entirely ectodermic. The gemmule larvae and the egg 

 larvae of siliceous sponges are similar in essential respects : the presence of the 

 germ layers and the differentiation of one pole. The bud embryo exhibits an- 

 cestral traits (the only other instance being the development of Epenthesis Mac- 

 Cradyi.

Körper nackt, sich mit Fremdkörpern umhüllend. Vier nicht geknöpfte, solide 

 Tentakel. Danach steht der Polyp zwischen den Hydrariae und allen anderen 

 Hydroidpolypen. Er stimmt mit Frotohydra Greeft', hat aber nur birnförmige 

 Nesselkapseln , kann also nicht mit jener identificiert werden. Es ist nur Knos- 

 penbildung beobachtet worden.
