Carelia cochlea — Atlas historical reconstruction of the complete adult fossil shell, Cooke 1931 plate VIII figure 12, no.77938B, labelled Kalihikai. Preserved russet-brown shell color is represented; living body appearance and Cooke’s conjectural black live color are not reconstructed. Coastal terrestrial soil and leaf litter are representative scenery, rather than an observed living station or evidence of present survival.
