The calcareous remains of foraminifera, corals, alcyonaria, Calcareous annelids, Crustacea, echinoderms, bryozoa, molluscs, tunicates, 'â ''''⢠and fishes seem to bulk more largely in deep-sea deposits than the siliceous remains. The Globigerina and Pteropod oozes and the Coral muds and sands owe their names to abundance in Fig. 116. Clathrocaniuin regintv, Haeckel. From the surface (magnified).

Reference may also be made to the teeth of sharks (see Figs. 126 and 127) and the earbones of whales (see Figs. 128 and 129) found occasionally in all deposits, but characteristically in the Red clay areas especially of the
