of the »Teichonidae« (with the exception of »Et/hardia Schulzeix, con- 
cerning which we both owe our anatomical information to Poléjaeff) 
were published and received in Europe many months before the date 
on which Dr. von Lendenfeld says he read the preliminary paper 
on which he bases his remarkable claim to independent discovery. 
As I have pointed out previously, Mr. Carter himself was the first 
to shew that »Teichonella labyrinthicac is a true Sycon, but this state- 
ment of his had passed quite unnoticed and no correct account of the 
anatomy of the sponge in question had appeared until the publication 
of my work. 
I am aware that in his Monograph of the Australian sponges 
Proc. Linn. Soc. N. S. W. Vol. IX p. 1140) Dr. von Lendenfeld 
accepted the »family« with some hesitation. He says »I have not seen 
any representatives of this family myself, but I am of opinion that they 
might perhaps he considered as colonies of Leucones or Sycones, as 
Marshall asserted, before Poléjaeff’s essay was published«. He also 
says of »Teichonella labyrinthica« (loc. cit. p. 1142) »The anatomy of 
this sponge is totally unknown, so that its name and position here are 
only preliminary«. How near Marshall’s opinion came to the truth of 
the matter Spongologists will be able to judge for themselves. Since 
the publication of the above remarks Dr. von Lendenfeld has 
repeatedly maintained the »family Teichonidae«, and continued to 
do so until the very year in which my preliminary results were 
published. In other words, from 1885 till 1890. Dr. von Lenden- 
feld stuck to the family, then, when the outcome of my researches on 
»T. labyrinthica« and »T. prolifera« had been published and sent to 
him, he suddenly dropped the »family« and adopted my views without 
giving any reasons for so doing. Surely it is taxing our credulity toa 
much to ask us to believe that he arrived at his results independently.

8. Über die Organisation der Choanoflagellaten. 
(Vorläufige Mittheilung.) 
Von Rudolf H. Franze, Assistent am Polytechnieum zu Budapest. 
eingeg. 30. December 1892. 
Gelegentlich des Studiums der Stigmata der Flagellaten, welche 
ich auch auf die sog. »Mundleiste« der Monadinen ausdehnte, wurde 
ich auf mehrere, bisher nicht erkannte Organisationsverhältnisse der- 
selben aufmerksam, welche mich veranlaßten, sowohl die Monadinen, 
als auch die Choanoflagellaten einer eingehenden Untersuchung zu
