Mode of Origin and Development of Vorticellce, after Pineau. ( X 200.) in size so as to constitute a sort of pedicle. In this form, according to Pineau, it resembled Actlnopkrys tedkellata. Other pediculated specimens were soon seen which had assumed a pyriform shape, and then the pedicle was no longer contractile, though the other rays still exhibited very slow movements. Some of these organisms presented the trace of a circular mouth at their free extremity, and specimens which had at- tained this grade of development seemed to increase in size, whilst the mouth became larger and was at last pro- vided with a circle of vibratile cilia. As the organisms still further increased in size, the rays gradually disap- peared, and the previously motionless pedicle also began.
