it is no more completely or darkly coloured in that than in 

 this. Usually the lateral borders are less callous, and less 

 deeply blackish-brown in G . friendii, but this is not sufficient 

 to specifically separate them. Their specific identity seems 

 certain.

Iredale proves the name C. umbilicata, Sowerby, to be 

 preoccupied by Dillwyn, and renames it C. hesitata; so C. 

 armeniaca becomes the species name, and hesitata the 

 varietal. Though the latter is found to the east of Australia 

 as far north as New South Wales, and is not very uncommon 

 in Tasmania, yet it has not been taken along the southern 

 coast of Victoria or South Australia, nor in my dredging 

 off this coast up to 300 fathoms. C. armeniaca was dredged 

 in the Great Australian Bight, somewhere west of Eucla, and 

 therefore in Western Australian waters.

This is recorded from New South Wales and Queensland, 

 and has been sent to me from Cape Banks, Byron Bay, and 

 Moreton Bay; from Cambridge Gulf, Broome, Carnarvon, 

 Geraldton, and Pelsart Island. I have taken it at Rottnest 

 Island and at Ellensbrook. It was given to me as from 

 Albany, but I did not find it myself when collecting there, 

 and am disposed to think it does not occur there, nor else- 

 where along the southern coast of Australia.

Menke localizes it on the western shore of New Holland; 

 Angas in Port Jackson, Brazier makes Botany Bay its 

 southern limit ; Gross' collection has examples from Moreton 

 Bay and North Queensland; Tate's North-west Australia; 

 and I have taken it at Ellensbrook, south of Cape Naturaliste. 

 Two fine specimens were given to me by a gentleman, who 

 had them given to him at Albany, but this locality is pro- 

 bably incorrect ; I found none there.
