Ad Hargitts Tubularia parasitica. I have been enabled to 

 observe the development of the western representative of the genus 

 Corymorpha, C. palma, a few facts concerning which will show, 

 I think, that T. parasitica is but a young form of the pendula 

 on which it was growing. Beschreibt kurz die Entwicklung der 

 C. palma, ein ausführlicherer Bericht soll später folgen.
