22 Dr. R. V. Lendenfeld on Australian Sponges. 



Luffaria digitata^ is very meagrely described, but I think 

 it highly probable that it is identical with a sponge described 

 eighteen years ago by Selenkaf as Spongilia cactos, and 

 which has been investigated by F. E. Schulze:}: and myself §. 

 Carter has, apparently, not seen my paper on Sponges of 

 Port Phillip, otherwise I think that my description of this 

 sponge would have been sufficient for identification. I have 

 named it Dendrilla rosea, which name, having priority, ought 

 to replace the name Luffaria digitata given by Carter ||. The 

 most important feature of the sponge is its peculiar subdermal 

 cavity. Carter does not mention this ; but as he does not say 

 anything about the canal-system at all, it is probable that he 

 never examined any section-series. 



Darwinella australimisis^ is represented in my collection, 

 but the canal- system is not described by Carter, so that it is 

 difficult to identify the species. 



With Aplysina Icevis^* of Carter, seven distinct species in 

 my collection might be identified. These are very different 

 from one another, but all coincide with Carter's diagnosis of 

 the above species. They are forms which lead to the Dysideidas 

 of Marshall ft, of which Carter's Pseudoceratina durissima\X 

 may be a true representative. 



The diagnosis given by Carter of Aplysina purpurea §§ led 

 me to believe that it might be identical with a sponge exa- 

 mined by me and named Ap>lysilla violacea || || ; but now it
