Cypraea tigris schilderiana C. N. Cate 1961

Specimens with a shell size larger than 150 mm in length have been reported, although shells larger than 120 mm are rare. In most places where Cypraea tigris occurs, it hides in crevices and is active mostly during the night. In Hawaii, however, it is often found out in the open on the reefs, and sometimes moving actively during the day. It has been suggested that because of its larger shell size, this cowrie has a more difficult time finding crevices large enough to hide.

Meyer's Cowrie Genomic Database Project (2005)(http://www.flmnh.ufl.edu/cowries/) says this taxon was tested but found no molecular evidence to support it as a separate evolutionary significant unit (ESU) from Cypraea tigris
