  Single 
  -spina 
  group. 
  

  

  Adactylus 
  bennetii 
  : 
  ? 
  spina 
  short 
  but 
  strong 
  

  

  Adkinia 
  bipunctidactyla

  slender, 
  deeply 
  grooved 
  

  

  Adkinia 
  zophodactylus

  ? 
  spina 
  very 
  slightly 
  shorter 
  and 
  

  

  more 
  slender

  in 
  bipunctidactyla 
  

   Stenoptilia 
  pterodactyla 
  : 
  ? 
  spina 
  longer 
  but 
  more 
  

  

  slender 
  than 
  in 
  bipunctidactyla, 
  deeply 
  grooved 
  and 
  

  

  sometimes 
  slightly 
  divided 
  at 
  the 
  point. 
  The 
  grooving 
  

  

  of 
  the 
  spina 
  seems 
  to 
  indicate 
  that 
  the 
  single 
  form 
  has 
  

  

  been 
  more 
  recently 
  acquired 
  than 
  in 
  some 
  other 
  species, 
  

  

  and 
  this 
  conclusion 
  is 
  supported 
  by 
  the 
  occasional
