Another sinistral Notocypraea and some interesting observations

摘要

I read with interest the excellent article on sinistral cowries by Harry Lee in the September 2010 issue of American Conchologist. Of particular interest was his reference to the Notocypraea declivis (G.B. Sowerby III, 1870) briefly mentioned in Griffiths's1962 review. The specific reference was this entry between his descriptions of Notocypraea declivis and Notocypraea dissecta (Iredale, 1831):"Remarks: The only sinistral specimen of Cypraeidae known to the author is in the South Australian Museum" (SAM). In April 1975 I wrote to the museum (SAM)inquiring about this shell, but a reply from the Curator of Marine Invertebrates, Dr. Zeidler, via his assistant Caroline Ristic,stated that no reference in their records to this or any other specimen of a sinistral Cvvraea could be found.
