I would also like to thank George and Bret for the screen saver, a great
Xmas present.

George there is one little problem, the Spondylus is not Spondylus
wrightianus but Spondylus imperialis, the difference is in the interstitial
spining, in imperialis the minor spines are v shaped with a centre minor
spine, this does not occur in wrightianus. It is a magnificent specimen that
you figure, the photography is excellent and shows the interstitial spining
perfectly.
