  Having 
  recently 
  been 
  busy 
  with 
  the 
  synonymy 
  of 
  some 
  of 
  

   the 
  Palsearctic 
  birds, 
  I 
  have 
  had 
  occasion 
  investigate 
  the 
  

   original 
  description 
  of 
  Emberiza 
  saharce. 
  Dr. 
  Sharpe 
  (Cat. 
  

   B. 
  Brit. 
  Mus. 
  xii. 
  p. 
  563) 
  gives 
  it 
  as 
  '^ 
  Tristram, 
  Ibis, 
  

   1859, 
  p. 
  295 
  ; 
  " 
  but 
  this 
  is 
  clearly 
  an 
  error, 
  for 
  the 
  species 
  

   was 
  known 
  by 
  that 
  name 
  several 
  years 
  before 
  1859, 
  and 
  

   Canon 
  Tristram 
  certainly 
  did 
  not 
  there 
  describe 
  it, 
  or 
  claim 
  

   to 
  do 
  so 
  — 
  he 
  merely 
  included 
  it 
  in 
  his 
  list 
  of 
  Algerian 
  

   birds 
  as 
  " 
  Fringillaria 
  saharae 
  of 
  Bonaparte," 
  and 
  remarked 
  

   on 
  the 
  differences 
  between 
  it 
  and 
  Emberiza 
  striolata. 
  The 
  

   earliest 
  reference 
  to 
  the 
  bird 
  that 
  I 
  can 
  find 
  is 
  that 
  of 
  Mal- 
  

   herbe, 
  who 
  in 
  his 
  list 
  of 
  the 
  birds 
  of 
  Algeria 
  (1855) 
  attributed 
  

   the 
  name 
  to 
  Levaillant, 
  jr., 
  as 
  ^'Emberiza 
  safiari,

  and 
  in 
  his 
  preface, 
  

   referring 
  to 
  this 
  work, 
  writes
