  Remarks. 
  — 
  Simia 
  leonina 
  Humboldt 
  was 
  based 
  on 
  two 
  individuals 
  

   seen 
  living 
  in 
  captivity 
  in 
  Popaydn, 
  Colombia. 
  They 
  were 
  said 
  to 
  

   have 
  been 
  brought 
  from 
  Mocoa 
  (river 
  and 
  town 
  at 
  head 
  of 
  Rio 
  

   Caquetd) 
  and 
  the 
  Rio 
  Putumayo, 
  at 
  eastern 
  base 
  of 
  the 
  Cordillera 
  

   Oriental, 
  Colombia. 
  The 
  original 
  description 
  and 
  colored 
  plate 
  

   (Humboldt, 
  op. 
  cii., 
  p. 
  15, 
  pi. 
  5) 
  indicate 
  a 
  marmoset 
  whose 
  identifiable 
  

   characters 
  correspond 
  to 
  those 
  of 
  Leontocebus 
  rosalia. 
  To 
  this 
  day 
  

   there 
  has 
  been 
  no 
  confirmation 
  of 
  the 
  natural 
  occurrence 
  of 
  a 
  member 
  

   of 
  the 
  genus 
  Leontocebus 
  anywhere 
  within 
  the 
  Amazonian 
  region. 
  

   Until 
  the 
  contrary 
  can 
  be 
  demonstrated, 
  it 
  is 
  fitting 
  to 
  dispose 
  of 
  

   leonina 
  in 
  the 
  synonymy 
  of 
  rosalia. 
  Leontopithecus 
  fuscus 
  Lesson 
  is 
  

   simply 
  a 
  new 
  name 
  proposed 
  for 
  Simia 
  leonina 
  Humboldt 
  preoccupied 
  

   by 
  Simia 
  leonina 
  Shaw, 
  1800. 
  Simia 
  albijrons 
  Thunberg 
  (1819, 
  

   p. 
  65, 
  pis. 
  3, 
  4) 
  had 
  been 
  considered 
  by 
  some 
  authors 
  a 
  Leontocebus. 
  

   Cabrera 
  (1940, 
  p. 
  403) 
  deemed 
  it 
  unidentifiable 
  and 
  also 
  showed 
  the 
  

   name 
  to 
  be 
  preoccupied 
  by 
  Simia 
  albijrons 
  Humboldt, 
  1812.
