  A living specimen observed. The entire shell is enveloped
      by the calymma and surrounded by radiating pseudopodia
      (drawn much too short). Between the two paired arms
      arises a large "sarcode-flagellum." The central chamber
      and the first enveloping ring are filled by the clear
      nucleus; the other rings and all the chambers of the
      arms contain numerous pink oil-globules.
