  On 
  the 
  Javan 
  Species 
  of 
  Zosterops. 
  

  

  Of 
  these 
  six 
  species 
  four 
  have 
  been 
  recorded 
  from 
  West 
  Java 
  

   and 
  two 
  from 
  East 
  Java. 
  Two 
  of 
  the 
  West-Javan 
  species 
  are 
  

   known 
  with 
  certainty 
  only 
  from 
  that 
  island, 
  and 
  diflFer 
  from 
  all 
  

   other 
  species 
  of 
  the 
  genus 
  in 
  having 
  the 
  crown 
  and 
  nape 
  ash- 
  

   grey, 
  in 
  strong 
  contrast 
  to 
  the 
  olive 
  of 
  the 
  rest 
  of 
  the 
  upper 
  

   parts. 
  They 
  have 
  been 
  regarded 
  as 
  so 
  aberrant 
  that 
  they 
  have 
  

   been 
  separated 
  under 
  the 
  generic 
  name 
  of 
  Oreosterops 
  (Bona- 
  

   parte, 
  Compt. 
  Rend, 
  xxxviii. 
  p. 
  264). 
  Zosterops 
  fallax 
  is 
  de- 
  

   scribed 
  as 
  very 
  common 
  in 
  West 
  Java, 
  and 
  Zostei'ops 
  j 
  avanica, 
  

   which 
  differs 
  from 
  it 
  principally 
  in 
  having 
  a 
  broad 
  white 
  eye- 
  

   stripe, 
  was 
  brought 
  from 
  West 
  Java 
  by 
  Dr. 
  Horsfield. 
  In 
  

   both 
  these 
  species 
  the 
  belly 
  and 
  flanks 
  are 
  yellow. 
  The 
  third 
  

   West-Javan 
  species 
  has 
  a 
  wide 
  range_, 
  from 
  South 
  Tenasserira 
  

   and 
  the 
  Malay 
  Peninsula 
  to 
  Borneo, 
  Sumatra, 
  and 
  Timor. 
  

   Zosterops 
  auriventer 
  belongs 
  to 
  the 
  typical 
  group 
  in 
  which 
  

   the 
  crown 
  and 
  nape 
  are 
  olive 
  like 
  the 
  rest 
  of 
  the 
  upper 
  parts. 
  

   It 
  may 
  at 
  once 
  be 
  distinguished 
  from 
  the 
  other 
  Javan 
  species 
  

   by 
  its 
  bright 
  yellow 
  belly, 
  which 
  is 
  very 
  conspicuous 
  between 
  

   the 
  ash-grey 
  flanks. 
  It 
  would 
  be 
  very 
  interesting 
  to 
  be 
  

   sure 
  that 
  the 
  locality 
  of 
  Timor 
  is 
  correctly 
  assigned 
  to 
  this 
  

   species, 
  and, 
  if 
  so, 
  to 
  know 
  whether 
  it 
  occurs 
  in 
  East 
  Java. 
  

  

  The 
  fourth 
  West-Javan 
  species 
  has 
  also 
  been 
  recorded 
  

   from 
  Sumatra 
  and 
  Borneo, 
  and 
  appears 
  to 
  be 
  closely 
  allied 
  

   to 
  the 
  species 
  described 
  from 
  East 
  Java. 
  Both 
  are 
  olive 
  

   above 
  and 
  yellow 
  beneath, 
  but 
  in 
  the 
  latter, 
  Zosterops 
  gallio, 
  

   there 
  is 
  a 
  black 
  spot 
  in 
  front 
  of 
  the 
  eye, 
  which 
  is 
  absent 
  in 
  

   the 
  former, 
  Zosterops 
  flava. 
  

  

  The 
  sixth 
  Javan 
  species 
  was 
  discovered 
  in 
  1886 
  by 
  Mr. 
  

   Whitehead, 
  at 
  an 
  elevation 
  of 
  5000 
  feet 
  above 
  sea-level, 
  near 
  

   Tosari 
  in 
  East 
  Java. 
  It 
  appears 
  to 
  have 
  been 
  identified 
  with 
  

   Zosterops 
  mmventer 
  (Sharpe, 
  Ibis, 
  1889, 
  p. 
  427) 
  — 
  a 
  perfectly 
  

   distinct 
  species 
  with 
  ash-grey 
  flanks 
  and 
  bright 
  yellow 
  belly. 
  

   Mr. 
  Whitehead's 
  bird 
  is 
  most 
  nearly 
  related 
  to 
  the 
  Indian 
  

   White-eye 
  {Zosterops 
  palpcbrosa) 
  , 
  and 
  is 
  probably 
  not 
  more 
  

   than 
  subspecifically 
  distinct 
  from 
  that 
  widely-spread 
  species. 
  

   In 
  the 
  colour 
  of 
  the 
  upper; 
  parts 
  it 
  is 
  intermediate 
  between 
  

   Zosterops 
  palpebrosa 
  and 
  Zosterops 
  simplex, 
  being 
  greener 
  

   than 
  the 
  Indian 
  species, 
  but 
  yellower 
  than 
  the 
  Chinese 
  bird.
