'â ^^Jv'""//! Fig. 10.- -Pscudodifflugia sp. circular mouth opening and mosaic shell (A). B, division stage. (Original.) are more or less globular or pyriform in shape. On such a proto- plasmic basis the shells of Difflugia species, Euglypha, Cyphoderia, Centropyxis, Arcella, etc., are deposited and these, once formed, are never changed (Fig. 10). Only rarely are these shelled rhizopods flattened or discoid as in Ilyalodiscus. The typical form in many shell-bearing or skeleton forming rhizo- pods may be due in its last analysis to the finer structure of the pro- toplasmic body in which the skeleton or shell parts are deposited. Dreyer (1892) has given much evidence to show that the form and size of the elements making up the skeletal or shell parts depend.
