Despite its incorrect formation (the correct one would be Cassididae, based on the genitive form of Cassis), the ICZN has placed the name Cassidae Latreille, 1825 on the official list of family names, therefore avoiding homonymy with Cassididae Stephens, 1831 (based on Cassida Linnaeus, 1758, a chrysomelid beetle); Opinion 1023 (1974, Bulletin of Zoological Nomenclature 31: 127–129).
Basket-hilted rapiers and sword-rapiers, characterised by pierced shell-guards, made during the same period are known as Pappenheimer rapiers.

The Registry of World Record Size Shells is a conchological work listing the largest (and in some cases smallest) verified shell specimens of various marine molluscan taxa.A successor to the earlier World Size Records of Robert J. L. Wagner and R. Tucker Abbott, it has been published on a semi-regular basis since 1997, changing ownership and publisher a number of times.
The maximum recorded shell length is 301 mm. [2] The shell of Cassis tuberosa is typically cream colored with dark brown spots. The dorsal surface will have fine growth lines and fine spiral lines to create a "canceled effect". [3]
Smaller rings may be attached to a main ring, as at Fig Island 1 in South Carolina and the Rollins shell ring in Florida. Shell rings in southwest Florida are often associated with large mounds and other shell works. Shell rings in Georgia average 53 metres (174 ft) in diameter, and those in South Carolina 64 metres (210 ft) in diameter.
