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 C. friendii, but this is not sufficient 
to specifically separate them. Their aes ised seems 
certain.

Iredale proves the name C. wmbilicata, Sowerby, to be 
preoccupied by Dillwyn, and renames it OC. 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 V ictoria or South Australia, nor in my dredging 
off this coast up to 300 fathoms. C. armeniaca was dredged 
in the Great Australian Bight, TO eee west of Eucla a 
therefore in Western ARR paLEE waters. 1 fositelir

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.
