  The 
  bones 
  of 
  the 
  carpus 
  and 
  manus 
  of 
  this 
  individual 
  are 
  

   only 
  in 
  part 
  preserved, 
  but 
  those 
  represented 
  in 
  figure 
  5 
  will 
  

   serve 
  to 
  indicate 
  the 
  general 
  nature 
  of 
  the 
  fore 
  foot. 
  There 
  

   were 
  apparently 
  five 
  digits 
  in 
  this 
  foot, 
  although 
  the 
  fifth 
  was 
  

   small 
  or 
  rudimentary. 
  The 
  metacarpals 
  were 
  quite 
  short, 
  as 
  

   indicated 
  by 
  the 
  third 
  and 
  fourth. 
  The 
  phalanges 
  were 
  also 
  

   short, 
  and 
  the 
  median 
  ones, 
  at 
  least, 
  possessed 
  claws. 
  

  

  The 
  above 
  description 
  and 
  figures 
  of 
  Stylinodon 
  will 
  in 
  

   themselves 
  be 
  conclusive 
  evidence 
  to 
  most 
  anatomists 
  that 
  this 
  

   genus 
  has 
  close 
  affinities 
  with 
  the 
  Edentates, 
  if 
  it 
  is 
  not 
  a 
  

   typical 
  member 
  of 
  that 
  group. 
  Its 
  relation 
  to 
  other 
  allied 
  

   genera 
  will 
  be 
  discussed 
  in 
  a 
  later 
  communication.

  The 
  reference 
  in 
  the 
  original 
  description 
  of 
  Stylinodon 
  to 
  its 
  

   resemblance 
  with 
  Toxodon 
  is 
  also 
  worthy 
  of 
  some 
  consideration, 
  

   as 
  the 
  latter 
  genus 
  is 
  now 
  believed 
  to 
  be 
  nearly 
  related 
  to 
  various 
  

   forms 
  long 
  considered 
  Edentates, 
  but 
  at 
  present 
  regarded 
  by 
  

   many 
  as 
  aberrant 
  Ungulates, 
  since, 
  notwithstanding 
  the 
  appar- 
  

   ent 
  resemblance 
  of 
  the 
  feet 
  to 
  those 
  of 
  Edentates, 
  the 
  teeth 
  

   indicate 
  affinities 
  with 
  the 
  perissodactyles.

  peculiar 
  group,

  Chalicotheria, 
  of 
  which 
  Chalico- 
  

   therium,

  is 
  the

  is
