t lie western end of the South Australian coast, and is found 



as far north as Rottnest. It is taken alive on the beach at 



Albany, and also in 100 fathoms, so that it has a wide range 

 of depth.

Gmelin gives hab.(1); Sowerby, in 1837, South Africa; 

 Kiener, Indian seas and shores of New Holland ; Angas gives 

 Guichen Bay, South Australia,- and adds, "It is a Tasmanian 

 species, not extending into the South Australian gulfs, where 

 several allied species have their habitat" ; Ten. Woods gives 

 "common" in Tasmania; Brazier questions the locality of 

 a specimen from Moreton Bay, or the identification of the 

 shell. But Hedley cites it from Queensland; and Hedley and 

 May record it from 100 fathoms off Cape Pillar, Tasmania. 



Sowerby, in his Thesaurus, ventures the opinion that 

 comptoni, declivis, piperita, and bicolor are all varieties of 

 angustata; while Beddome creates the varieties subcarnea , 

 Ancey, mayi, and albata. Pritchard and Gatliff discuss this 

 question fully, and declare all to be varieties. I have no 

 hesitation in supporting these authors and in confirming 

 Sowerby's further suspicion as to the varietal position of C. 

 pulicaria, Reeve. C. angustata, Gmelin, the typical ventri- 

 cose form, is not very common in South Australia, but is 

 most so in the eastern part, as MacDonnell Bay, where occurs 

 the very elegant form figured by Reeve, pi. xvii., fig. 91, 

 covered with a bluish-white enamel. It is found, however, 

 along the whole coastline of South Australia to the west, as 

 far as explored, and at Albany up to 24'5 mm. in length. 

 Like all its varieties it may have several transverse ridges.
