120 Descriptions of Neiv, 



Eschar a patellaria. I have not seen Moll's work; but 

 Heller's figure certainly looks different, and he shows the 

 cells all connected by six tubes. No avicularia have been 

 seen. 



It agrees with Diachoris in nothing but the disjunction of 

 the cells, and seems to me certainly a true Membranipora. 



I add a list of species of Membranipora, known to me to 

 occur in Victoria : — 



M. membranacea, L. 



M . pilosa, L. 



M . flagellum, M/G. 



M. umbonata, Busk. 



M. cervicomis, Busk. 



M. Rosselii, Sav. 



M. patellaria, Esper. 



M. Lacroixii, Sav. 



M. papulifera, M/G. 



M. acifera, M'G. 



M. serrata, M f G. 



M. pyrula, Hincks ( = lineata, M/G.). 



M. corbula, Hincks. 



M. flustroides, Hincks. 



A form differing only from the English in having the 

 spines longer and narrower, and the ovicell narrower and 

 deeper, has been dredged by Mr. Wilson, and by myself at 

 Port Phillip Heads. I have not seen the avicularia. 



M. punctigera, Hincks. 

 M. Flemmingii, Busk. 



I have examined two imperfect specimens, seemingly 

 referable to this species, dredged at Port Phillip Heads by 

 Mr. Wilson. 



M. (Lepralia) trifolium, M'G. 

 M. spinosa, Q. and G. 

 M. ciliata, M'G. 

 M. albispina, M'G. 

 M. radicifera, Hincks. 

 M. permunita, Hincks. 

 M. catenularia, Hincks. 

 M. crassa, M'G.
