Shell of the Week: The Royal Bonnet

The elegant Royal Bonnet, Sconsia grayi A. Adams, 1855, is a close relative of the famous Scotch Bonnet, Semicassis granulata. The Royal Bonnet, however, dwells in deeper water than the Scotch Bonnet, living at depths from 27−640 m (about 90−2,100 ft.) The species may reach 50 mm (about 2 inches) in length. The immature shell illustrated measures about 30 mm (or 1.2 inches.) It was collected (dredged) in early October during the 2021 Northeastern Gulf of Mexico Cruise led by Dr. Greg Herbert of the University of South Florida, and photographed by me aboard the Research Vessel Hogarth.
