Turrid, plural turrids, is a common name for a very large group of predatory sea snails, marine gastropod mollusks which until recently were all classified in the family Turridae. However, recently the family was discovered to be polyphyletic and therefore was split into a number of families. The single most complete collection of turrids in museums worldwide is in the Academy of Natural Sciences of Philadelphia malacology collection; this is because of specialized collecting by the American malacologist Virginia Orr Maes (1920-1986).
