please help confirm identities of these shells

[shellhunk]

Wow guys I really envy your knowledge about shells. <img src="smile/eek.gif" alt="smile/eek.gif" style="border:0" /> This shell was sold as brunneus in the shell market (Philippines). I bought it as brunneus (They all look the same) but while checking the shells I just noticed the spines look different from the rest. I had an idea it's palmarosae (I researched a bit). Just had second thoughts coz I'm not an expert. And it is only 1 in the bunch of brunneus.

At least now I know.  <img src="images/smiley/smile.gif" alt="" border="0" /> I'm going to check for palmarosae whenever I see brunneus in a basket.   <img src="images/smiley/biggrin.gif" alt="" border="0" />

Thank you guys.  <img src="images/smiley/clap.gif" alt="" border="0" />
