 Hey Mark,

I think it depends upon who you believe or what book you read.  Some folks
put Angaria in with Turbinidae - despite the difference in opercs and shell
structure.  The Compendium seems to lump Angaria in with Astraeinae and your
Astrea heliotropium.  Me, I keep them separate because I don't want to
change the shell drawer layout.
