ALDINGA AXD THE RIVER-MTTRKAY CLIFFS, SOUTH AUSTRALIA. ;303 



Stoliczka {loc. cit. p. 142) suggested that probably the fossil was 

 C. coronopus ; and so far as this specimen permits a judgment, I cer- 

 tainly agree with him. 



Loc. Living: Coasts of Britain and France ; Mediterranean. Fossil: 

 Pliocene : Crag ; Pliocene of Italy and Sicily ; Mt. Gambler {B.) ;

A specimen from the River-Murray Cliffs apparently grew over 

 the stem of some seaweed, and rises into irregular nodulations. 

 The zocecia are ovate with an avicularium at the side by the lower 

 part of the oral aperture ; oral aperture suborbicular, angular at 

 the proximal edge, forming a sinus ; large spatulate avicularia dis- 

 tributed over the zoarium. Ovicell globose with large punctures. 



The size of the cells, apertures, and avicularia is the same as in 

 my Naples specimens.

A small badly preserved specimen from Adelaide is growing on 

 MicroporeUa ferrea^ W. This has smaller zocecia than a recent 

 specimen from Glenelg, S. Australia, in which the aperture is 0*13 

 millim., while in the fossil it is only O'l millim. In the fossil no 

 ovicells are preserved, and the avicularia do not rise above the 

 zooecia, whereas in the recent specimen the ovicells are the same as 

 those from Naples, and the avicularia, although they turn more in- 

 wards, closely resemble those from Naples. 



This I believe is related to Lagenipora spinulosa, Hincks. 



Loc. Living: Wilson Promontory and Queenscliff, Victoria (il/rtcG^.); 

 Glenelg, S. Australia (A. W. W. coU.). Fossil : Leithakalk of Nuss- 

 dorf (Vienna) {A. W. W. coU.), Adelaide. 



62. Cellepoea divisa, sp. nov. 



The zoarium is subglobular, 6-8 millim. in diameter. The zooecia 

 are small and irregular in shape, with a small round aperture 0*13 

 millim. wide, and inside this there is a plate extending about one 

 third across the aperture (fig. 1). There is a central " pit " round
