Yes this is Cypraea (Erosaria) erosa. The other is an immature Strombus (Canarium) urceus.

 Paul Monfils thank you very much for your info. Do you know just how large the Strombus (Canarium) urceus can grow?
Thanks again Richard

Hi Richard,

Strombus urceus is usually about 35 to 45 mm in length when mature, but there is a slender, tall-spired form that reaches at least 70 mm.  I have often wondered if that form should be described as a different species, but so far no-one has done so.  Here's a picture of that form (66 mm):

Yes Paul, that is the form I have that is around the 70mm mark. I agree with you, it should be a named form as I have seen no intergrades.
