  is 
  the 
  A. 
  rufi- 
  

   venti'is, 
  Smith, 
  at 
  present 
  standing 
  iu 
  the 
  Museum 
  under 
  

   the 
  name 
  of 
  A. 
  exilis 
  (Temm.). 
  A. 
  exilis 
  my 
  father 
  held 
  

   to 
  be 
  a 
  synonym 
  of 
  A. 
  hartlauhi 
  in 
  immature 
  plumage, 
  but 
  

   A. 
  hartlauhi, 
  A. 
  minullus, 
  and 
  A. 
  erythropus 
  (Hartlaub) 
  stand 
  

   separated 
  in 
  the 
  Museum. 
  Of 
  the 
  little 
  A. 
  minullus 
  we 
  

   have 
  23 
  specimens, 
  but 
  only 
  one 
  of 
  A. 
  erythropus, 
  obtained 
  

   through 
  Carfrae 
  in 
  1858. 
  

  

  Of 
  A. 
  rufiventris 
  we 
  have 
  twelve 
  specimens 
  from 
  Natal, 
  

   Lydenburg, 
  King 
  William-'s 
  Town, 
  Shoa, 
  Transvaal, 
  &c. 
  In 
  

   confirmation 
  of 
  a 
  theory 
  advanced 
  in 
  *The 
  Ibis' 
  for 
  1889 
  

   (p. 
  572), 
  that 
  species 
  will 
  sometimes 
  throw 
  out 
  a 
  " 
  sport 
  ^' 
  

   resembling 
  other 
  species, 
  it 
  may 
  be 
  mentioned 
  that 
  adult 
  

   males 
  of 
  our 
  British 
  Sparrow-Hawk 
  {A. 
  7iisus) 
  occasionally 
  

   vary, 
  so 
  as 
  to 
  resemble 
  A. 
  rufiventris, 
  in 
  having 
  the 
  breast 
  

   and 
  underparts 
  a 
  clear 
  rufous 
  without 
  any 
  transverse 
  bands 
  

   at 
  all. 
  Such 
  a 
  bird, 
  shot 
  in 
  Norfolk, 
  I 
  saw 
  some 
  years 
  ago 
  

   at 
  Mr. 
  Gunn's 
  shop, 
  and 
  another 
  was 
  obtained 
  by 
  Mr. 
  Henry 
  

   Doubleday 
  ('Zoologist,' 
  1875, 
  p. 
  4429). 
  But 
  the 
  best 
  

   example 
  of 
  this 
  plain-chested 
  variety 
  was 
  shot 
  in 
  Northum- 
  

   berland 
  and 
  is 
  in 
  the 
  Newcastle 
  Museum. 
  

  

  When 
  my 
  father 
  published 
  his 
  ' 
  List 
  ' 
  he 
  had 
  not 
  seen 
  

   Microhierax 
  sinensis, 
  Sharpe, 
  figured 
  by 
  David 
  and 
  Oustalet 
  

   under 
  the 
  name 
  of 
  M. 
  chinensis, 
  and 
  he 
  never 
  got 
  one 
  

   for 
  the 
  Museum 
  ; 
  but 
  he 
  was 
  shown 
  one 
  in 
  1887 
  by 
  

   Mr. 
  Styan 
  killed 
  at 
  Foochow 
  [cf. 
  Ibis, 
  1887, 
  pp. 
  234, 
  470), 
  

   and 
  he 
  notes 
  that 
  " 
  it 
  seemed 
  the 
  largest 
  of 
  the 
  genus, 
  in 
  

   coloration 
  very 
  like 
  M. 
  melanoleucus." 
  The 
  localities 
  given 
  

   for 
  it 
  by 
  David 
  are 
  the 
  province 
  of 
  Kiangsi, 
  in 
  the 
  centre 
  of 
  

   Southern 
  China, 
  and 
  Nankin. 
  This 
  species 
  differs 
  from 
  

   M. 
  melanoleucus 
  in 
  having 
  a 
  white 
  spot 
  at 
  the 
  back 
  of 
  the 
  

   neck, 
  but 
  Mr. 
  Seebohm 
  doubts 
  this 
  being 
  a 
  specific 
  diff'erence 
  

   (P. 
  Z. 
  S. 
  1890, 
  p. 
  345). 
  Besides 
  M. 
  sinensis 
  we 
  require 
  also 
  

   M. 
  melanoleucus. 
  

  

  Of 
  Microhierax 
  fringillarius 
  (Drap.) 
  the 
  Museum 
  has 
  a 
  

   large 
  series 
  from 
  Singapore, 
  Banjarmassing, 
  Baram, 
  Batavia^ 
  

   and 
  Sumatra. 
  

  

  Of 
  M. 
  erythrogenys 
  (Vigors) 
  we 
  have 
  four 
  from 
  Mindanao
