152 AUSTRALIAN SPONGES DESCRIBED BY CARTER, 



The Boltenia is probably Boltenia australis. The name Boltenia 

 australiensis given by Carter (1) is not warranted. 



Chondrilla nucula O.S. is mentioned as occurring in Port 

 Phillip. (2) I have not found any specimens of this Sponge in 

 any part of the Australian coast. I have, however, described a 

 species of Chondrilla as C. secunda, n.s., from Port Phillip, in a 

 paper read some time ago before the Linnean Society of N.S.W. 

 (3) This species is somewhat different from C. nucula O.S., in 

 the shape of its spicules, and particularly the configuration of the 

 canal -system, but which outwardly appears very similar to the 

 Adriatic species, of which I brought a specimen with me. I think 

 it very probable that Carter's specimen is to be referred to my 

 Chondrilla secunda, a Sponge very abundant in Port Phillip. 



Luffaria digitata (4) is very meagerly described, but I think it 

 highly probable that it is identical with a Sponge described 

 eighteen years ago by Selenka (5) as Spongelia cactos, which has 

 also been investigated by F. E. Schulze (6) and myself (7). 



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. (8)
