  The 
  majority 
  of 
  the 
  species 
  referred 
  to 
  in 
  this 
  communication 
  were 
  

   collected 
  by 
  Staff-Surgeon 
  K. 
  H. 
  Jones 
  at 
  Hong-Kong 
  and 
  Wei- 
  

   hai-wei 
  between 
  the 
  years 
  1905 
  and 
  1907, 
  but 
  those 
  from 
  Shi 
  Tao, 
  

   in 
  the 
  province 
  of 
  Shantung, 
  were 
  obtained 
  by 
  the 
  late 
  Mr. 
  C. 
  A. 
  

   Schwilp, 
  who 
  resided 
  at 
  that 
  place. 
  The 
  species 
  from 
  Wei-hai-wei 
  

   include 
  four 
  which 
  were 
  not 
  observed 
  there 
  in 
  1901-2, 
  and 
  one 
  

   of 
  these 
  at 
  any 
  rate, 
  Eulota 
  {Cathaica) 
  fasciola, 
  Drap., 
  has 
  probably 
  

   been 
  introduced 
  since 
  that 
  time, 
  pei'haps 
  from 
  Shanghai, 
  where 
  it 
  

   is 
  fairly 
  common. 
  This 
  species 
  is 
  very 
  conspicuous 
  and 
  not 
  at 
  all 
  

   likely 
  to 
  be 
  overlooked. 
  The 
  remarkably 
  local 
  distribution 
  of 
  many 
  

   species 
  as 
  noticed 
  in 
  our 
  former 
  paper 
  ^ 
  is 
  again 
  borne 
  in 
  upon 
  us. 
  

   Many 
  species 
  are 
  here 
  noted, 
  on 
  account 
  of 
  the 
  localities 
  in 
  which 
  

   they 
  were 
  found, 
  in 
  evidence 
  of 
  their 
  area 
  of 
  distribution. 
  

  

  Helicakion 
  imperatoe, 
  Gould. 
  

  

  Of 
  this 
  common 
  Hong-Kong 
  species 
  a 
  specimen 
  was 
  taken 
  at 
  

   Little 
  Hong-Kong 
  Wood 
  in 
  1906, 
  which 
  instead 
  of 
  being 
  of 
  the 
  

   usual 
  reddish 
  horn 
  colour 
  was 
  of 
  a 
  distinct 
  greenish 
  hue. 
  This 
  is 
  

   the 
  only 
  shell 
  of 
  this 
  species 
  so 
  coloured 
  which 
  was 
  observed 
  at 
  

   Hong-Kong. 
  

  

  EuLOTA 
  (Cathaica) 
  FASCIOLA 
  (Drap.). 
  

  

  This 
  species, 
  there 
  is 
  little 
  doubt, 
  has 
  been 
  introduced 
  into 
  Wei- 
  

   hai-wei 
  since 
  1902, 
  perhaps 
  from 
  Shanghai, 
  with 
  which 
  port 
  there 
  

   is 
  constant 
  communication, 
  especially 
  during 
  the 
  summer 
  months, 
  

   but 
  possibly 
  from 
  Tien-tsin 
  to 
  the 
  north, 
  or 
  even 
  from 
  the 
  mainland 
  

   opposite. 
  This 
  is 
  not 
  a 
  species 
  which 
  is 
  easily 
  overlooked, 
  and 
  it 
  

   was 
  not 
  observed 
  on 
  the 
  mainland 
  of 
  Shantung. 
  On 
  the 
  island 
  of 
  

   Wei-hai-wei 
  it 
  is 
  confined 
  to 
  the 
  residential 
  portion, 
  over 
  which 
  

   it 
  is 
  rapidly 
  spreading, 
  being 
  particularlj^ 
  partial 
  to 
  gardens 
  and 
  

   their 
  walls. 
  The 
  specimens 
  are 
  of 
  fair 
  size, 
  and 
  all 
  of 
  them 
  present 
  

   one 
  band 
  on 
  the 
  bod^^-wliorl 
  with 
  the 
  exception 
  of 
  two, 
  in 
  one 
  of 
  

   which 
  tliere 
  are 
  two 
  bands 
  and 
  the 
  other 
  is 
  bandlcss. 
  One 
  immature 
  

   sinistral 
  specimen 
  was 
  obtained. 
  

  

  SucciNEA 
  Sinensis, 
  Gray. 
  

  

  It 
  is 
  of 
  interest 
  to 
  note 
  that 
  this 
  species 
  is 
  commonly 
  enough 
  

   found 
  at 
  Hong-Kong 
  in 
  different 
  parts 
  of 
  the 
  island 
  and 
  at 
  various 
  

   altitudes, 
  but 
  always 
  in 
  flower-pots. 
  Although 
  often 
  to 
  be 
  seen 
  

   wandering 
  away 
  from 
  the 
  pots 
  in 
  which 
  they 
  live, 
  they 
  do 
  not 
  

   seem 
  able 
  to 
  establish 
  themselves 
  elsewhere. 
  Probably

  species
