A pebble deriving its shape from a zoophyte apparently related to the Ventriculites [Spongites labyrinthieus, of Mantell). The aperture at the base has arisen from the decomposition of the process of attachment. Fig. 15. A pebble enclosing part of the base of a Ventriculite ; the circular spots on the largeend are sections of the ramifications of the stirps or base of the zoophyte; for thisfigure and the following are drawn in an inverted position. Fig. 16, is a similar fossil, split vertically, and showing the enclosed stem of the FOSSIL FAUNA. 107 PLATE Zoophytes. Fig. 1. A spongite [Scyplda costata, of Goldfuss), from Switzerland. The fossil spongeous bodiesnamed Scyphia, are characterized by the mass or body being either cylindrical,simple or branched; fistulous, and terminating in a rounded pit; entirely composedof a firm reticulated tissue. Like the other bodies comprised in the group ofAmorphozoa, the form in this genus is exceedingly diversified, and as the structure isoften but obscurely shown, the determination of these fossils is oftentimes is however convenient, in the present state of our knowledge, to distinguish theprincipal kinds by names which may be modified or abandoned, when the structureand natural affinities of the original organisms are more accurately determined.
