  From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]: 
 
  Amitosis  \Am`i*to"sis\,  n.  [NL.  See  {A-}  not  and  {Mitosis}.] 
  (Biol.) 
  Cell  division  in  which  there  is  first  a  simple  cleavage  of 
  the  nucleus  without  change  in  its  structure  (such  as  the 
  formation  of  chromosomes),  followed  by  the  division  of  the 
  cytoplasm;  direct  cell  division;  --  opposed  to  {mitosis}.  It 
  is  not  the  usual  mode  of  division,  and  is  believed  by  many  to 
  occur  chiefly  in  highly  specialized  cells  which  are  incapable 
  of  long-continued  multiplication,  in  transitory  structures, 
  and  in  those  in  early  stages  of  degeneration. 
 
  From  WordNet  r  1.6  [wn]: 
 
  amitosis 
  n  :  the  direct  method  of  cell  division  characterized  by  simple 
  division  of  the  nucleus  without  formation  of  chromosomes
