  5. 
  Lacerta 
  muralis, 
  Lain 
  - 
  . 
  

  

  In 
  every 
  respect 
  undistinguishable 
  from 
  Spanish 
  and 
  Portu- 
  

   guese 
  specimens. 
  

  

  6. 
  Psammodromus 
  microdactylies, 
  Bttg. 
  

  

  The 
  number 
  of 
  specimens 
  sent 
  by 
  M. 
  Vaucher 
  now 
  amounts 
  

   to 
  twenty- 
  one. 
  In 
  addition 
  to 
  these 
  I 
  have 
  also 
  examined 
  

   two 
  from 
  Mogador, 
  collected 
  by 
  Lieut. 
  Quedenfeldt 
  and 
  

   kindly 
  sent 
  to 
  me 
  for 
  the 
  British 
  Museum 
  by 
  Prof. 
  F. 
  E. 
  

   Schultze. 
  I 
  am 
  thus 
  enabled 
  to 
  draw 
  up 
  the 
  following 
  sup- 
  

   plementary 
  notes 
  on 
  this 
  little-known 
  species, 
  which 
  has 
  not 
  

   hitherto 
  been 
  found 
  out 
  of 
  Morocco. 
  

  

  The 
  number 
  of 
  femoral 
  pores 
  varies 
  from 
  10 
  to 
  13 
  on 
  each 
  

   side, 
  the 
  usual 
  number 
  being 
  12. 
  The 
  coloration 
  of 
  the 
  upper 
  

   parts 
  in 
  fresh 
  specimens 
  varies 
  from 
  pea-green 
  to 
  olive, 
  with 
  

   or 
  without 
  brown 
  or 
  black 
  spots, 
  which 
  may 
  be 
  mixed 
  with 
  

   white, 
  as 
  in 
  P. 
  hispanicus 
  ; 
  a 
  more 
  or 
  less 
  distinct 
  brown 
  or 
  

   reddish 
  lateral 
  band 
  is 
  constantly 
  present 
  ; 
  lower 
  surfaces 
  

   white, 
  outer 
  row 
  of 
  ventrals 
  lemon-yellow 
  ; 
  throat 
  of 
  males 
  

   bluish. 
  Young 
  with 
  small 
  black 
  and 
  white 
  ocelli 
  on 
  the 
  

   sides 
  ; 
  upper 
  lip 
  pure 
  white 
  ; 
  a 
  pure 
  white 
  black-edged 
  streak 
  

   from 
  the 
  eye 
  to 
  above 
  the 
  tympanum 
  and 
  a 
  second 
  from 
  the 
  

   angle 
  of 
  the 
  mouth 
  through 
  the 
  lower 
  half 
  of 
  the 
  tympanum 
  

   to 
  the 
  axil. 
  

  

  7. 
  Psammodromus 
  algirus, 
  L. 
  

  

  8. 
  Acanthodactylus 
  vulgaris, 
  var. 
  lineomaculatus, 
  D. 
  & 
  B. 
  

  

  9. 
  Chalcidts 
  ocellatus, 
  Forsk. 
  

  

  The 
  specimens, 
  four 
  in 
  number, 
  sent 
  by 
  M. 
  Vaucher 
  from 
  

   Tangier 
  belong 
  to 
  the 
  colour-variety 
  which 
  I 
  have 
  desig- 
  

   nated 
  as 
  var. 
  C 
  in 
  the 
  ' 
  Catalogue 
  of 
  Lizards.' 
  The 
  upper 
  

   surfaces 
  are 
  bronzy 
  brown 
  above, 
  without 
  any 
  spots, 
  except 
  

   in 
  some 
  specimens 
  a 
  small 
  basal 
  margin 
  to 
  each 
  scale, 
  and 
  

   with 
  a 
  light 
  pale 
  brown 
  or 
  golden 
  upper 
  and 
  a 
  black 
  lower 
  

   lateral 
  band 
  ; 
  lips 
  with 
  black 
  and 
  white 
  tessellation. 
  They 
  

   have 
  32 
  scales 
  round 
  the 
  body. 
  I 
  may 
  here 
  remark 
  that 
  a 
  

   specimen 
  from 
  Assab, 
  collected 
  by 
  Dr. 
  Ragazzi 
  and 
  recently 
  

   communicated 
  to 
  me 
  by 
  the 
  Marquis 
  Doria, 
  has 
  only 
  24 
  scales 
  

   round 
  the 
  body 
  ; 
  it 
  differs 
  from 
  the 
  typical 
  form 
  (A) 
  only 
  

   in 
  the 
  absence 
  of 
  ocelli 
  on 
  the 
  back. 
  The 
  variation 
  in 
  the 
  

   number 
  of 
  longitudinal 
  rows 
  of 
  scales 
  therefore 
  ranges 
  from 
  24 
  

   to 
  38 
  in 
  this 
  species.
