please help confirm identities of these shells

Hi paul, the palmarosae from S. India to Thailand are probably the prettiest. They are the ones with the pink fronds everyone wants. As you say, ones from the Philippines etc. can be very plain. I do consider torrefactus to be a good species, mainly by reason of shell morphology. I generally consider microphyllus to be a much smaller and slightly shorter spined shell, the colouring also seems to be more constant; very fine dark brown lines on a white background. I am looking into distribution at the moment to see if there is any reason to separate the species geographically too.
Cheers,
Dave
