  Variations. 
  — 
  Apart 
  from 
  the 
  description 
  of 
  indi- 
  

   vidual 
  variations, 
  which, 
  as 
  we 
  have 
  seen, 
  are 
  very 
  

   considerable 
  in 
  this 
  species, 
  attempts 
  have 
  been 
  made 
  

   to 
  distinguish 
  a 
  broad-snouted 
  and 
  a 
  sharp-snouted 
  

   variety, 
  to 
  which 
  Fatio 
  has 
  given 
  the 
  names 
  of 
  brevi- 
  

   rostris 
  and 
  acutirostris. 
  This 
  distinction 
  cannot 
  be 
  

   upheld, 
  as 
  we 
  find 
  the 
  two 
  forms 
  occurring 
  pro- 
  

   miscuously, 
  and 
  the 
  prognathism 
  affecting 
  only 
  young 
  

   or 
  half-grown 
  specimens. 
  The 
  only 
  form 
  which 
  

   appears 
  to 
  be 
  entitled 
  to 
  varietal 
  distinction 
  is 
  the 
  

   Spanish 
  var. 
  parvipalmata, 
  which 
  is 
  constantly 
  dis- 
  

   tinguished 
  by 
  a 
  shorter 
  web, 
  as 
  we 
  have 
  seen 
  above,
