  Bulletin 
  of 
  the 
  British 
  

  

  Fringilline 
  bird 
  from 
  the 
  Sandwich 
  Islands. 
  Mr. 
  Rothschild 
  

   had 
  proposed 
  for 
  it 
  the 
  name 
  of 
  Pseudonestor 
  xanthophrys, 
  

   and 
  had 
  prepared 
  the 
  following 
  description 
  : 
  — 
  

  

  Pseudonestor, 
  gen. 
  nov. 
  

   This 
  genus 
  is 
  nearest 
  allied 
  to 
  Psittacirostra, 
  but 
  differs 
  in 
  

   the 
  following 
  points 
  : 
  — 
  

  

  1. 
  Male 
  and 
  female 
  are 
  similar 
  in 
  colour 
  and 
  markings, 
  

   whereas 
  they 
  are 
  quite 
  differently 
  coloured 
  in 
  Psittacirostra. 
  

  

  2. 
  The 
  female 
  is 
  considerably 
  smaller 
  than 
  the 
  male, 
  

   whereas 
  the 
  sexes 
  are 
  similar 
  in 
  size 
  in 
  Psittacirostra. 
  

  

  3. 
  The 
  principal 
  difference 
  is 
  that, 
  whereas 
  the 
  female 
  of 
  

   Pseudonestor 
  has 
  a 
  beak 
  similar 
  to 
  that 
  of 
  Psittacirostra 
  

   though 
  much 
  more 
  curved, 
  the 
  male 
  of 
  Pseudonestor 
  has 
  an 
  

   enormously 
  hooked 
  bill, 
  much 
  resembling 
  in 
  shape 
  that 
  of 
  a 
  

   Nestor 
  Parrot, 
  the 
  maxilla 
  being 
  nearly 
  twice 
  the 
  length 
  of 
  

   the 
  mandible. 
  In 
  Psittacirostra, 
  on 
  the 
  other 
  hand, 
  the 
  

   bills 
  of 
  the 
  sexes 
  are 
  the 
  same.
