Hello to all and thank you for so many of you welcoming me to the list.
I am still trying to photograph & scan all my cypraea.  I am putting
data on a spreadsheet and have one question on the average sizes of
cypraea.

I only have the book "Cowries" by Dr. John Taylor & Jerry Walls
published in 1975 for reference.  Many of you recommended several
websites which also list average sizes for cypraea.  I have noticed that
the average sizes listed on Hardy's site are different than those in the
Taylor/Walls book.  In your opinion, which should I use?  I will be
getting the Guide to Worldwide Cowries by Dr. Felix Lorenz soon to help
me learn more about my collection.

Thank you,
Karen
