Good Morning!

I need some help on identifying four small Pectinids; they are on our club URL.   Go to - www.stlshell.com.   At the top of the opening page, click on "Site Map."   Then scroll down to "Membership," where you should find three names.   Click on
"Linda & William Bush," and you should get the pictures of four small Pectinids, arranged in order of descending size.   One of these was tentatively identified as a young vexillum, but I have no way of knowing which one - the dealer who sent them didn't indicate which one.

Thanks ahead of time,
Linda
