Latreille (1825) separated them with family rank under the name Lamellata. Guilding (1829) proposed the emended form polyplakiphora, and finally Dall (1870) proposed as a further emendation polyplaciphora, Fischer (1885), Haddon (18SU), Pilsbry (1892), Sykes (1896), and Thiele (1910) all accepted Gray's name poly- plaoophora.
