Amoeba diffluens, exhibiting a few of its changes of form. The genera Difflugia, Arcella, and Cyphidium (1,2, 3, fig. 7) seem to be merely Amoebae endowed with a power of constructing for them- selves a carapax or shelly covering of various forms, from the orifices of which the fluent body of the animalcules can be made to protrude, and thus become convertible into instruments of locomotion. In Cyclidium, Pantotrichum, and Clucto- monas, and their loricated representatives, C/ies- totypla, C/uftoglcna, Peridinium, and Gleno- dinitim, forming the families Cyclidida? and Peridinaeadae, we first find a new system of locomotive organs making their appearance in the shape of vibratile cilia. The locomotive cilia are variously disposed in different genera; sometimes they are disse- minated over the entire surface of the animal, either irregularly or arranged in regular rows ; sometimes they are only partially distributed or are confined to the region of the mouth and anterior part of the body ; but, whatever their situation, their action is similar; they are inces- santly in a state of active motion, either pro- pelling the animalcule through the water, or causing currents to flow in definite directions, by the agency of which food is brought to the oral opening. 1.
