Despite the uncertainty of the pseudopodia as a basis of classification, their structure among the Rhizopoda is frequently so characteristic that the identification of some species of Amceba is comparatively easy. Thus Amceba protens has large and blunt pseudopodia in the adult phase, while the young form (known as A. radiosd)1 has sharper, stiffer, and hyaline pseudopodia. When a pseudopodium of A. proteus starts from the periphery, it continues as a stream until, as a rule, a long, lobose structure results. When, ho

When, however, a pseudopodium of A. blattce Butschli or of A. limicola Rhumbler starts from the periphery of the spherical body, it resembles a miniature eruption. A break is ,-X-—L.
