  The 
  liistory 
  of 
  this 
  species 
  is 
  curious. 
  Originally 
  part 
  of 
  Gould's 
  

   hursatella, 
  it 
  was 
  described 
  by 
  Pfeiffer 
  in 
  1849 
  as 
  coarctata. 
  He 
  then 
  

   recognized 
  that 
  that 
  name 
  was 
  preoccupied, 
  and 
  abandoned 
  it 
  in 
  favour 
  

   of 
  cavernula, 
  H. 
  & 
  J., 
  a 
  totally 
  different 
  shell. 
  Meantime 
  Hombron 
  

   and 
  Jacquinot 
  had 
  described 
  it 
  as 
  turricida 
  (nom. 
  praeoc.) 
  and 
  Reeve 
  

   under 
  its 
  present 
  name 
  of 
  streptaxon, 
  which 
  was 
  forthwith 
  adopted 
  by 
  

   Pfeiifer 
  himself. 
  

  

  Garrett 
  notes 
  that 
  a 
  " 
  variety 
  (local) 
  occurs 
  which 
  is 
  uniform 
  

   whitish". 
  The 
  short 
  description 
  given 
  in 
  the 
  Voyage 
  au 
  Pole 
  Slid 
  is 
  

   stated 
  to 
  liave 
  been 
  drawn 
  up 
  from 
  the
