The excreta of these animals are associated with a certain amount of slimy albuminoid matter, and in cer- tain localities these excreta become so numerous that the term " coprolitic mud" has been proposed for the deposits containing them. The animal remains found in deep- ""^y- sea deposits are either siliceous or calcareous, those of a chitinous char- acter being extremely rare, if not entirely absent. The siliceous remains of radiolaria (see Figs. 110 to 117) and the spicules of siliceous sponges are widely distributed over the ocean- fioor, the radiolarian skeletons being so abundant in certain regions as to make up a very large part of the deposit, which.
