  faunae 
  certainly 
  have 
  much 
  in 
  common. 
  The 
  following 
  species 
  are, 
  so 
  

   far 
  as 
  we 
  at 
  ])resent 
  know, 
  peculiar 
  to 
  these 
  two 
  islands 
  and 
  the 
  smaller 
  

   ones 
  immediately 
  adjacent 
  to 
  them 
  :

  Tlie 
  following' 
  additional 
  species 
  are 
  common 
  to 
  the 
  two 
  islands 
  and 
  

   range 
  to 
  the 
  north, 
  but 
  seem 
  to 
  reach 
  their 
  southwestern 
  limit 
  in 
  

   Basilan.

  Z6?o- 
  

   cephus 
  cinnamomens 
  on 
  the 
  other 
  hand, 
  aie 
  common 
  to 
  Mindanao 
  and 
  

   Basilan, 
  and 
  range 
  to 
  the 
  westward, 
  but 
  do 
  not 
  get 
  farther 
  north 
  than 
  

   Mindanao. 
  

  

  So 
  much 
  for 
  the 
  resemblaiu^es 
  between 
  the 
  two 
  islands. 
  There 
  are, 
  

   however, 
  a 
  number 
  of 
  more 
  or 
  less 
  important 
  differences. 
  Eight 
  

   species 
  are, 
  so 
  far 
  as 
  we 
  at 
  present 
  know, 
  peculiar 
  to 
  Mindanao. 
  They 
  

   are 
  : 
  

  

  1. 
  linho 
  ijiiDH'yi. 
  5. 
  rrionoclnlus 
  hicoJor.

  Some 
  of 
  these 
  apparent 
  diiferences 
  will 
  doubtless 
  disappear 
  as 
  w^ 
  

   learn 
  more 
  of 
  the 
  birds 
  of 
  Basilan, 
  which 
  are 
  much 
  less 
  well 
  known 
  

   than 
  those 
  of 
  Mindanao, 
  but 
  that 
  island 
  also 
  has 
  its 
  peculiar 
  species, 
  

   and 
  there 
  is 
  little 
  probability 
  that 
  more 
  than 
  one 
  of 
  them 
  exists 
  in 
  

   Mindanao. 
  They 
  are 
  as 
  follows: 
  

  

  1. 
  I'hdholrcron 
  hriinueiceps. 
  4. 
  PtiJock'hla 
  hasilauica. 
  

  

  2. 
  Penelophhs 
  basilauicits. 
  5. 
  Dendrobia,s1ss 
  hasHanica. 
  

  

  3. 
  Maeronus 
  strlatieeps. 
  

  

  We 
  may 
  admit 
  that 
  such 
  Mindariao 
  forms 
  as 
  Buho 
  gurneyi, 
  Priono- 
  

   chilus 
  hicolor 
  and 
  Parus 
  nehrkornw 
  may 
  have 
  been 
  overlooked 
  in 
  Basi- 
  

   lan, 
  and 
  that 
  Demlrobiastes 
  hasilanica 
  may 
  have 
  escaped 
  detection 
  in 
  

   Mindanao, 
  but 
  it 
  is 
  decidedly 
  improbable 
  that 
  genera 
  like 
  Crauorrhiniis 
  

   and 
  Bolbopsittacus 
  should 
  have 
  escaped 
  all 
  the 
  collectors 
  who 
  have 
  

   visited 
  Basilan.
