This shell has generally been referred to as C. scottii, 

 Brod., but Gray has priority of publication. Broderip gives 

 as the habitat the Strait of Sunda, near Angia, Java, and 

 Kiener the Moluccas; but Sowerby, in 1837, Garden Island, 

 Swan River. Menke in 1843 confirms this in his "Western 

 Coast of New Holland." Reeve cites not only Swan River 

 for the typical shell, but Port Lincoln for his variety B, 

 which is evidently C. thersites, Gaskoin. Ten. Woods writes, 

 "In more than one work it is spoken of as Tasmanian, but 

 I cannot find any trace of this species among cellections." 

 So also Tate and May reject it for Tasmania. It was listed 

 by Adcock for South Australia. Mr. E. H. Matthews has 

 a shell from Yorke Peninsula which was regarded as C. 

 scottii; it is a somewhat elongated example of C . thersites. 



I took it on Bunbury beach. Captain Irvine, of Fre- 

 mantle, told me that several specimens may somtimes be 

 obtained from the piers of the jetty, apparently feeding on 

 the coral-like incrustations. Tate's collection contained 5 

 examples ranging up to 81 mm. x 40 x 34 mm. from Geo- 

 graphe Bay. At Esperance Captain Douglas gave me 4 

 individuals said to have been gathered locally. These were 

 much longer, wider, and higher.

Gaskoin's habitat is "Salt Creek, Yorke Peninsula, South 

 Australia, on clusters of zoophytes at 2-3 fathoms." Angas 

 cites this as "the only place where it has hitherto been 

 found." But Reeve's variety B of C scottii from Port Lin- 

 coln is almost certainly this species. It has since been taken 

 in numbers at Black Point, Gulf St. Vincent, and in Hard- 

 wicke Bay, Spencer Gulf. One was dredged by me full
