Could it be "Florida Sea Shells" by Bertha Aldrich and Ethel
Snyder ( Houghton Mifflin, 1935) ? ( A lovely old gem and
my lst shell book ever, purchased ~ 1950-1952). Mentions
the junonia, although not extensively. This book also mentions
"The Shell Book " by Julia Rogers (New York, Doubleday Doran, 1931)
