Well, Everyone!
Here I am again working on some of the shells in that same
old collection our club bought. I have Kevin Lamprell's
book on Spondylus and am trying to i.d. them (most have a
label, but they are innacurate).
I keep encountering the erm "gibbous" to refer to the
shell shape. Will someone explain this term to me,
please?
Thanks,
linda
