  DISCOGLOSSID^. 
  

  

  quite 
  as 
  short 
  and 
  broadly 
  rounded 
  as 
  in 
  the 
  Sardinian 
  

   form. 
  As 
  already 
  observed 
  by 
  Lataste, 
  this 
  difference 
  

   is 
  no 
  greater 
  than 
  that 
  between 
  specimens 
  of 
  Bana 
  

   tew,]3oraria, 
  and 
  is 
  certainly 
  not 
  more 
  constant. 
  With 
  

   regard 
  to 
  the 
  third 
  character, 
  I 
  need 
  simply 
  refer 
  to 
  my 
  

   tables 
  of 
  measurement 
  and 
  to 
  Camerano's 
  own 
  table, 
  

   where 
  Sardinian 
  as 
  well 
  as 
  Sicilian 
  specimens 
  are 
  

   shown 
  to 
  have 
  the 
  tibia 
  less 
  than 
  half 
  the 
  length 
  of 
  

   head 
  and 
  body. 
  

  

  Bedriaga 
  also 
  is 
  inclined 
  to 
  retain 
  D. 
  sardus 
  as 
  a 
  

   distinct 
  form, 
  althouofh 
  admittino^ 
  that 
  the 
  existence 
  

   of 
  annectant 
  specimens 
  renders 
  a 
  j)recise 
  definition 
  

   impossible. 
  On 
  the 
  whole, 
  he 
  finds 
  the 
  body 
  shorter 
  

   in 
  proportion 
  to 
  the 
  head 
  and 
  limbs 
  in 
  Corsican 
  and 
  

   Sardinian 
  specimens 
  than 
  in 
  those 
  from 
  Algeria 
  and 
  

   Portugal. 
  That 
  there 
  is 
  nothing 
  constant 
  in 
  that 
  

   supposed 
  difference 
  may 
  be 
  seen 
  from 
  the 
  following 
  

   measurements 
  (in 
  millimetres) 
  of 
  four 
  adult 
  males, 
  the 
  

   heads

  which 
  are

  It 
  will 
  be 
  noticed 
  that 
  the 
  Spanish 
  and 
  Algerian 
  

   specimens 
  o. 
  and 
  h 
  have 
  the 
  head 
  a 
  little 
  longer 
  in 
  

   proportion 
  to 
  the 
  body 
  than 
  in 
  the 
  Algerian 
  c 
  and 
  the 
  

   Sardinian 
  d 
  ; 
  that 
  the 
  width 
  of 
  the 
  head 
  below 
  the 
  eyes 
  

   is 
  as 
  great 
  in 
  proportion 
  in 
  the 
  Algerian 
  c 
  as 
  in 
  the 
  

   Sardinian 
  d; 
  and 
  that 
  the 
  hind 
  limb 
  is 
  shorter 
  in 
  pro- 
  

   portion 
  in 
  the 
  Algerian 
  c 
  than 
  in 
  the 
  Sardinian 
  d. 
  

  

  Heron-Hoyer's 
  D. 
  auritus 
  is 
  founded 
  on 
  Algerian 
  

   specimens 
  (which 
  had 
  been 
  previously 
  referred 
  by 
  

   Camerano 
  to 
  D. 
  scovazzii), 
  supposed 
  to 
  differ

  the 
  

   Europeans
