  Differing 
  from 
  L. 
  Schwilpi 
  chiefly 
  hj 
  its 
  much 
  smaller 
  size 
  and 
  by 
  

   the 
  columella, 
  which, 
  being 
  scarcely 
  twisted 
  and 
  not 
  nearly 
  so 
  oblique, 
  

   is 
  not 
  expanded 
  into 
  the 
  very 
  thick 
  callus 
  of 
  that 
  form 
  ; 
  the 
  aperture 
  

   is 
  also 
  more 
  ovate 
  and 
  much 
  less 
  auriform 
  in 
  shape.

  species 
  

   appears

  a 
  very 
  shallow

   which 
  runs

  the 
  side 
  of

  Hah. 
  —

  Province,

  Confined 
  to 
  a 
  limited 
  area 
  like 
  most 
  species 
  of 
  the 
  genus 
  in 
  China. 
  

  

  ViviPARA 
  Chinensis, 
  Gray. 
  

  

  This 
  common 
  Chinese 
  species 
  was 
  obtained 
  at 
  Shi 
  Tao, 
  and 
  as 
  it 
  

   has 
  been 
  noticed 
  in 
  our 
  previous 
  paper 
  as 
  occurring 
  at 
  the 
  Chusaii 
  

   Islands 
  and 
  about 
  Hong-Kong, 
  it 
  has 
  a 
  considerable 
  distribution 
  north 
  

   and 
  south. 
  Like 
  the 
  previous 
  species 
  it 
  appeared 
  to 
  be 
  closely
