Brazier records it from Bellinger River beaches, New 

 South Wales; Hedley from Queensland. It has been sent to 

 me from Carnarvon, North-west Australia. Brazier cites 

 it from Rowley Shoals, and I have taken it at Ellensbrook. 

 It has not been found on the southern shores.

Gray gives New Holland as its habitat; Shirley cites 

 Moreton Bay. Ellensbrook, west coast of Western Australia, 

 one beach specimen in good condition, colour slightly faded. 

 Hedley, in Jour. Roy. Soc. W. Austr., vol. i., 1916 (1914-

 1885, vol. vii., p. 190, writes: — "C. fallax, E. A. Smith, is 

 an unfigured variety, credited to Western Australia. It 

 differs from the normal shell in being larger, more pyriform, 

 white spots smaller and less clearly defined ; they appear to 

 blend into the fawn colour of the dorsum, which is paler than 

 in C. cribraria." My shell is rather less than I'l inch, the 

 maximum of C. cribraria given by Trybn, and less still than 

 my cabinet specimens of this species, which reach 125 inch. 

 The relative sizes of my example, and the largest of these are 

 27 mm. x 16 x 13 and 30 mm. x 18 x 14*5. Its dimen- 

 sions, therefore, do not suggest G. fallax, nor does the colour 

 ornament, for the spots are typically large, and allowing for 

 some fading of the yellow-brown foundation tint are 

 typically distinct. It seems, therefore, to be a typical 

 C. cribraria. It has not been found on the southern shore 

 of Australia. .

It has been taken along the shore of South Australia 

 from MacDonnell Bay to Fowler Bay and on St. Francis 

 Island. It reaches 16 mm. in length, and is well and 

 typically coloured. Dredged off Beachport, 2 in 40 fathoms, 

 up to 11 '5 mm., 2 in 110 fathoms, and in 200 fathoms 1 

 showing colour spots ; off Cape Jaffa, in 90 fathoms 1 eroded ; 

 off Cape Borda, Kangaroo Island, in 55 fathoms 2 very poor,
