PLATE 125. Concharida. Diam. Page. Fig. 1. Conchopsis aspidium, n. sp., × 150 [1726] Lateral view, from the left side. Fig. 2. Conchopsis aspidium, n. sp., × 300 [1726] The hinge of another specimen, in which the two valves are connected by a ligament (as in figs. 8 and 9, Pl. 123). Fig. 3. Conchopsis orbicularis, n. sp., × 200 [1725] Lateral view, from the left side. Fig. 4. Conchopsis navicula, n. sp., × 150 [1727] Lateral view, from the right side. In the lower (posterior) half of the figure is visible the central capsule with its dark nucleus, in the upper (anterior) half the phæodium with two broad sagittal wings. Fig. 5. Conchopsis navicula, n. sp., × 400 [1727] Three single pores with their hexagonal external frame and the dilated internal ovate or ampullaceous channel. Fig. 6. Conchopsis navicula, n. sp., × 400 [1727] Hinge of the shell, from the right side. Fig. 7. Conchopsis compressa, n. sp., × 150 [1725] Lateral view from the left side. The triangular central capsule with the dark nucleus is visible. Fig. 8. Conchopsis compressa, n. sp., × 150 [1725] Dorsal view of the upper valve with its keel. Fig. 9. Conchopsis pilidium, n. sp., × 80 [1726] The two valves separated and seen obliquely, half from the lateral, half from the internal side. The inner opening of each valve is bordered and partly closed by a broad horizontal velum or diaphragm like the deck of a boat.
