  Volvox  \Vol"vox\,  n.  (Bot.) 
  A  genus  of  minute,  pale-green,  globular,  organisms,  about  one 
  fiftieth  of  an  inch  in  diameter,  found  rolling  through  water, 
  the  motion  being  produced  by  minute  colorless  cilia.  It  has 
  been  considered  as  belonging  to  the  flagellate  Infusoria,  but 
  is  now  referred  to  the  vegetable  kingdom,  and  each  globule  is 
  considered  a  colony  of  many  individuals.  The  commonest 
  species  is  Volvox  globator  often  called  globe  animalcule.

  plants,  having  locomotive  powers  something  like  those 
  of  animals.  Among  these  are  {Volvox},  the 
  {Desmidiac[ae]},  and  the  siliceous  {Diatomace[ae]}.
