REMARKS The taxonomy of Trianguloscalpellum regium was recently reviewed ( Young 1998a: 28 ). This species has been reported from all the oceans, but probably this distribution encompasses more than one species ( Young 1998a ). It is frequently recorded from the abyssal plain of the North Atlantic.
