Cypraea and conus

[dave r]

Hi Rafa, the first pictures seem to be of some species of Ranellidae.The other three are:
#1 Conus ? catus, coronatus, too worn to positively identify.
#2 Cypraea errones
#3 Cypraea caurica
It would really help if when you post these pictures you could tell us where the shells were found and also what size they are. This would make identification a lot easier in many cases.
Cheers,
Dave
