The Scotch bonnet, Semicassis granulata granulata, also known as the ridged bonnet, is a medium-sized subspecies of sea snail, a marine gastropod mollusc in the subfamily Cassinae, the helmet snails and bonnet snails.
The name "Scotch bonnet" comes from the fact that the checkered shell of this species has a vague resemblance to a traditional tartan hat, as used to be commonly worn in Scotland.
