  BRACHYTELEUS 
  

  

  The 
  genus 
  Brachyteleus 
  was 
  here 
  first 
  established, 
  and 
  B. 
  

   arachnoides 
  was 
  redescribed 
  as 
  Brachyteles 
  ( 
  !) 
  macrotarsus.

  Under 
  his 
  genus 
  Eriodes 
  = 
  Brachyteleus 
  three 
  species 
  are 
  

   named. 
  (£.) 
  arachnoides; 
  (E.) 
  tuberijer, 
  and 
  (£.) 
  hemi- 
  

   dactylus, 
  the 
  last 
  two 
  = 
  B. 
  arachnoides. 
  E. 
  hemidactylus 
  

   was 
  simply 
  another 
  name 
  proposed 
  for 
  hypoxanthus 
  because 
  as 
  

   the 
  Author 
  supposed, 
  it 
  had 
  been 
  given 
  to 
  two 
  species, 
  he 
  

   believing 
  that 
  the 
  presence 
  or 
  absence 
  of 
  the 
  thumb 
  constituted 
  

   a 
  specific 
  character.
