  et 
  m^me 
  bien 
  plus 
  haut." 
  As 
  Aoius 
  does 
  not 
  occur 
  in 
  the 
  Bogotd 
  

   region 
  proper, 
  which 
  is 
  savanna, 
  the 
  type 
  locaUty 
  is 
  here 
  restricted 
  

   to 
  that 
  of 
  the 
  Goudot 
  specimens. 
  This 
  is 
  the 
  only 
  authentic 
  locality 
  

   for 
  specimens 
  of 
  the 
  original 
  series. 
  Ample 
  material 
  from 
  forests 
  of 
  

   the 
  Quindio 
  (Cordillera 
  Central, 
  department 
  of 
  Caldas) 
  is 
  available 
  

   and 
  more 
  has 
  been 
  recorded 
  in 
  literature. 
  Specimens 
  from 
  localities 
  

   in 
  the 
  typical 
  region 
  (Quindio 
  Pass, 
  Laguneta, 
  etc.) 
  conform 
  to 
  the 
  

   original 
  description 
  in 
  every 
  detail. 
  

  

  Distribution. 
  — 
  Forested 
  parts 
  of 
  the 
  Colombian 
  Andes 
  exclusive 
  of 
  

   the 
  northern 
  half 
  of 
  the 
  Sierra 
  de 
  Perija. 
  

  

  Characters. 
  — 
  Average 
  darkest 
  of 
  the 
  races; 
  pelage 
  extremely 
  coarse, 
  

   long 
  and 
  lax. 
  

  

  Remarks. 
  — 
  The 
  "diagnostic" 
  characters 
  of 
  lemurinus 
  are 
  premised 
  

   on 
  evidence 
  that 
  the 
  majority 
  of 
  specimens 
  from 
  the 
  interior 
  of 
  

   Colombia 
  live 
  at 
  higher 
  altitudes 
  than 
  those 
  of 
  the 
  coast 
  and 
  show, 
  

   consequently, 
  longer, 
  coarser, 
  and 
  laxer 
  pelage. 
  Beyond 
  this 
  no 
  

   single 
  character 
  serves 
  to 
  unite 
  individuals 
  here 
  held 
  to 
  represent 
  

   lemurinus 
  into 
  an 
  assemblage 
  distinct 
  from 
  all 
  others. 
  Variation 
  in 
  

   color 
  and 
  character 
  of 
  pelage 
  is 
  so 
  great 
  among 
  these 
  night 
  monkeys 
  

   that 
  two 
  discreet 
  family 
  groups 
  of 
  the 
  same 
  locality 
  are 
  apt 
  to 
  differ 
  

   more 
  from 
  each 
  other 
  than 
  either 
  of 
  them 
  from 
  a 
  series 
  of 
  any 
  other 
  

   locality 
  in 
  the 
  Colombian 
  Andes. 
  Specimens 
  from 
  the 
  typical 
  region 
  

   in 
  the 
  Rio 
  Cauca 
  drainage 
  of 
  the 
  Cordillera 
  Central 
  include 
  individuals 
  

   inseparable 
  from 
  others 
  throughout 
  the 
  range 
  of 
  the 
  genus. 
  The 
  

   partial 
  synonymy 
  of 
  lemurinus 
  given 
  above 
  reflects 
  the 
  variability 
  of 
  

   the 
  race. 
  

  

  Aotus 
  lanius 
  Dollman 
  was 
  described 
  as 
  "a 
  mountain 
  form 
  allied 
  to 
  

   Aotus 
  trivirgatus." 
  Neither 
  comparison 
  with 
  nor 
  reference 
  to 
  lemur- 
  

   inus 
  Geoffroy 
  was 
  made. 
  The 
  type 
  is 
  the 
  same 
  specimen 
  previously 
  

   identified 
  by 
  Sclater 
  (op. 
  cit., 
  1890) 
  as 
  vociferans. 
  A 
  specimen 
  from 
  

   the 
  Rio 
  Toche, 
  a 
  stream 
  descending 
  from 
  the 
  southern 
  flank 
  of 
  Mount 
  

   Tolima 
  and 
  draining 
  into 
  the 
  Magdalena, 
  may 
  be 
  regarded 
  as 
  strictly 
  

   representative 
  of 
  lanius. 
  It 
  is 
  richly 
  brown 
  in 
  color 
  and 
  almost 
  

   indistinguishable 
  from 
  a 
  brown 
  phase 
  individual 
  of 
  lemurinus 
  from 
  

   the 
  typical 
  Quindio 
  region 
  across 
  the 
  divide 
  in 
  the 
  Rio 
  Cauca 
  drain- 
  

   age. 
  As 
  in 
  the 
  preceding, 
  descriptions 
  of 
  aversus 
  and 
  pervigilis 
  by 
  

   Elliot 
  include 
  no 
  reference 
  to 
  lemurinus 
  and, 
  it 
  may 
  be 
  added, 
  the 
  

   vague 
  villosus 
  Gray, 
  1847, 
  from 
  the 
  same 
  general 
  region. 
  Topotypes 
  

   of 
  aversus, 
  from 
  Fusagasuga 
  in 
  the 
  Magdalena 
  Valley, 
  southwest 
  of 
  

   Bogota, 
  are 
  in 
  pale 
  brown 
  phase 
  with 
  a 
  well-defined 
  blackish 
  median 
  

   dorsal 
  band. 
  This 
  last 
  character 
  is 
  not 
  so 
  uniformly 
  clear 
  in 
  any 
  

   of 
  the 
  available 
  series 
  from 
  the 
  Cordillera 
  Central. 
  These 
  topotypes 
  

   differ 
  even 
  more 
  widely 
  from 
  the 
  typical 
  series 
  of 
  aversus 
  and 
  serve 
  to 
  

   emphasize 
  the 
  lack 
  of 
  consistency 
  in 
  characters 
  of 
  this 
  oi' 
  any 
  other 
  

   group 
  of 
  night 
  monkeys 
  described 
  from 
  Colombia. 
  No 
  two 
  series
