Haeckel 1865 Tafel

Ernst Haeckel's 6 week stay in Villefranche in March-April 1864 allowed him make observations on living cells. This plate is from "Ueber den Sarcodekörper der Rhizopoden" (1865). New species he described in his 1865 report are Acanthodesmia polybrocha, or Polyplecta polybrocha (fig.3, Actinelius purpureus (fig. 4) and Cyrtidosphaera echinoides, now known as Acanthosphaera echinoides (Fig. 5).
