Identification help

[taz]

Hello

I'm slowly sorting through some shells, most of which I have been able to identify. However, there are some which I'm not sure of.

I've posted photos on my web site here:

<a href="http://www.tasmoths.net/shells/" target="_blank"><!-- m --><a class="postlink" href="http://www.tasmoths.net/shells/">http://www.tasmoths.net/shells/</a><!-- m --></a>

There are too many to expect anyone to identify them all but I'm hoping that someone may help me out with some  of the easier/obvious ones.

Shells 1 to 8 seem to be mostly  <i>Cypraea arabica</i> but a few of them look a little different.

I think #17 is <i>Cypraea errones</i>, #23 is some sort of Melongena sp and #25 is <i>Ryssota otaheitana</i> .

Any help is much appreciated.
