  The 
  type 
  of 
  Callithrix 
  infulatus 
  "Licht 
  .," 
  is 
  in 
  the 
  Berlin 
  

   Museum. 
  Lichtenstein's 
  name 
  is 
  only 
  in 
  manuscript 
  and 
  of 
  course 
  is 
  

   not 
  tenable. 
  But 
  Kuhl, 
  when 
  in 
  Berlin, 
  described 
  in 
  his 
  Beitrage 
  

   Zoologie, 
  Lichtenstein's 
  specimen 
  under 
  the 
  name 
  that 
  was 
  already 
  

   given, 
  and 
  therefore 
  it 
  will 
  stand 
  as 
  Aotus 
  infulatus 
  Kuhl, 
  and 
  

   Spix's 
  name 
  of 
  felinus 
  given 
  three 
  years 
  after 
  will 
  become 
  a 
  synonym. 
  

  

  Bates 
  (1. 
  c.) 
  states 
  he 
  once 
  saw 
  an 
  individual 
  of 
  this 
  species 
  

   which 
  was 
  surprisingly 
  tame. 
  It 
  was 
  as 
  lively 
  and 
  nimble 
  as 
  the 
  

   species 
  of 
  Cebus, 
  less 
  mischievous, 
  but 
  far 
  more 
  confiding 
  in 
  its 
  

   disposition 
  and 
  delighted 
  to 
  be 
  caressed 
  by 
  all 
  who 
  came 
  into 
  the 
  

   house. 
  Its 
  cleanliness 
  and 
  pretty 
  ways 
  and 
  appearance 
  made 
  it 
  a 
  great 
  

   favorite. 
  The 
  gentle 
  disposition 
  of 
  this 
  particular 
  animal, 
  however, 
  

   might 
  be 
  attributed 
  to 
  the 
  treatment 
  it 
  received 
  from 
  its 
  owner, 
  who 
  

   allowed 
  it 
  to 
  sleep 
  with 
  him 
  in 
  his 
  hammock 
  and 
  to 
  nestle 
  in 
  his 
  

   bosom 
  as 
  he 
  lay 
  reading. 
  Bates 
  further 
  relates, 
  under 
  the 
  name 
  of 
  

   N. 
  felinus, 
  that 
  he 
  kept 
  one 
  of 
  this 
  species 
  for 
  many 
  months, 
  a 
  young 
  

   one 
  having 
  been 
  given 
  him 
  by 
  an 
  Indian. 
  A 
  colony, 
  to 
  which 
  this 
  one 
  

   belonged, 
  was 
  discovered 
  by 
  the 
  Indian; 
  for 
  these 
  animals 
  even 
  when 
  

   sleeping 
  are 
  aroused 
  by 
  the 
  least 
  noise, 
  and 
  if 
  one 
  passes 
  by 
  the 
  tree 
  in 
  

   which 
  they 
  have 
  their 
  nest, 
  a 
  number 
  of 
  owl-like 
  striped 
  faces 
  appear 
  

   at 
  the 
  edge 
  of 
  the 
  hollow 
  in 
  the 
  trunk. 
  He 
  was 
  obliged 
  to 
  keep 
  it
