Conchology (Gk. conche, shell), the science of shells, sometimes used as synonymous with the scientific study of molluscs, which were formerly classified according to the formation of their shells. Later science, however, studies them from the point of view of their internal characteristics, and the word conchology is now applied rather to the study and collection of shells simply, without regard to their occupants.
