in den Schlußbemerkungen folgender Passus enthalten ist, den ich in 

 wörtlicher Übersetzung wiedergebe : »Die sonderbare Umhüllung der 

 Gemmulae von Sp. fragilis [Lordü] und Trochospongilla erinaceus 

 entspricht genetisch dem unscheinbaren Netz zwischen 

 den Amphidisken der Meyenia- {Ephydatia-)ATten, des- 

 gleichen demjenigen zwischen den Belegnadeln der 

 Spongilla- Arten. In beiden Fällen functionirt dieses aus Luft- 

 kammern bestehende Gewebe als hydrostatischer Apparat, der bei den 

 zwei europäischen Arten: Sp. fragilis und Trochospo7igilla erinaceus 

 zur mächtigsten Entwicklung gelangt ist.« 



Ich habe beiden Herren meine Arbeit zugeschickt, sie scheinen 

 aber obige Stelle ganz übersehen zu haben.
