genus. The shells that are associated in this division exhibit a vivid and 
pleasing variation of colour, and their simple and unvarying structure 
renders them familiar and easy to distinguish. Although the genus Conus 
has increased in number and variety of species since the publication of 
the ‘Systema Nature’ in as full and rapid proportion as other genera of
