  Another 
  character 
  used 
  by 
  Dobson 
  for 
  the 
  distinction 
  of 
  

   the 
  different 
  species 
  is 
  the 
  insertion 
  of 
  the 
  wing-membranes 
  ; 
  

   but 
  I 
  have 
  observed 
  that 
  this 
  character 
  is 
  not 
  so 
  valuable 
  as 
  

   in 
  the 
  Vespertilionidas, 
  as 
  it 
  is 
  not 
  possible 
  to 
  establish 
  

   exactly 
  the 
  point 
  of 
  insertion 
  of 
  the 
  wing-membranes. 
  

  

  I 
  am 
  indebted 
  for 
  the 
  opportunity 
  of 
  making 
  these 
  re- 
  

   searches 
  to 
  Mr. 
  Oldfield 
  Thomas, 
  who 
  permitted 
  me 
  to 
  use 
  

   the 
  large 
  material

  Gentlemen, 
  — 
  In 
  an 
  exploration 
  of 
  this 
  island, 
  in 
  company 
  

   with 
  Mr. 
  Meade- 
  Waldo, 
  we 
  have 
  collected 
  a 
  large 
  number 
  of 
  

   the 
  Chaffinch, 
  which 
  invariably 
  differs 
  in 
  its 
  coloration 
  from 
  

   its 
  congeners 
  in 
  the 
  islands 
  of 
  Teneriffe, 
  Canaria, 
  and 
  

   Gomera. 
  I 
  venture 
  without 
  hesitation 
  to 
  describe 
  it 
  as 
  

   distinct, 
  and 
  subjoin 
  the 
  diagnosis. 
  

  

  I 
  am, 
  

  

  Yours 
  faithfully, 
  

  

  H. 
  B. 
  Tristram.
