Note 111 — 3. Genus—TETRACLITA. Pl. 10, 11.
Reading edition
The longitudinally folded walls, as described by Spengler, the blue colour, the habitat, namely, associated with B. tintinnabulum from the East Indies, and more especially the expression “Valvulæ operculi cardine dentato mobilis,” apparently referring to the highly prominent articular ridge of the scutum, leave little doubt on my mind that I have rightly named the present species.
