摘要：

Electron microscopic studies of Arcella vulgaris have revealed a sexual process occurring in cysts. The evidence includes: 1) synaptonemal complexes in prophasic nuclei, 2) two consecutive divisions different from vegetative mitosis, 3) degeneration of certain products of these nuclear divisions, and 4) fusion of nuclei indicating karyogamy. The process is apparently autogamy preceded by a two-division meiosis. The testate amoebae can no longer be considered asexual.
