RE: Strange Casmaria (Cassis)
This is Casmaria ponderosa. A misplaced varix like this can occur in any species of Cassidae. It indicates the location of the shell lip during a past period of restricted shell growth, which could be caused by a period of unusually low temperature, or a period when food was scarce, etc.
