From p. 115 of Lee, H.G., 2009. Marine Shells of Northeast Florida.
Jacksonville Shell Club, Inc. 204 pp. + 19 color plates. 28 May.
[The figured shell was collected on Amelia Island, Nassau County, Florida. On
line 6, "gulf" should be "Gulf, and "C. semiplicata" should appear in
Roman, not italic, type.
review of museum specimens in early 2014, we believe the Perry shell to be C.
scutulata rather than an un-named species as indicated five years earlier.]
