  In 
  this 
  review 
  of 
  Lagothrix 
  but 
  one 
  species 
  is 
  recognized 
  : 
  L. 
  

   humboldti 
  Geoff., 
  = 
  L. 
  lagotricha 
  Humb. 
  The 
  latter 
  name 
  

   is 
  among 
  the 
  synonyms 
  but 
  the 
  law 
  of 
  priority 
  is 
  disregarded. 
  

   L. 
  cana, 
  in 
  fact 
  all 
  described 
  forms, 
  are 
  considered 
  as 
  merely 
  

   representing 
  a 
  variety 
  of 
  coloring 
  of 
  the 
  one 
  species 
  resulting 
  

   from 
  age 
  and 
  sex.

   Three 
  species 
  are 
  recognized: 
  L. 
  cana; 
  L. 
  humboldti 
  = 
  L. 
  

   lagotricha, 
  which 
  name 
  is 
  rejected 
  as 
  insufficiently 
  described, 
  

   and 
  L. 
  infumata

  made 
  a 
  synonym; 
  and

  Two 
  species 
  are 
  apparently 
  recognized 
  in 
  this 
  List, 
  L. 
  cana 
  

   and 
  L. 
  infumata; 
  but 
  under 
  the 
  last 
  as 
  its 
  first 
  synonym 
  is 
  

   Simia 
  cana 
  Geoff. 
  (!) 
  Of 
  course 
  a 
  form 
  cannot 
  be 
  both 
  a 
  

   species 
  and 
  a 
  synonym, 
  and 
  the 
  method 
  adopted 
  by 
  the 
  Author 
  

   is 
  puzzling 
  to 
  say 
  the 
  least. 
  If 
  cana 
  and 
  infumata 
  are 
  the 
  same, 
  

   then 
  cana, 
  having 
  been 
  published 
  eleven 
  years 
  before 
  infumata, 
  

   becomes 
  the 
  name 
  of 
  the 
  species, 
  and 
  infumata 
  the 
  synonym, 
  

   but 
  never 
  otherwise 
  as 
  von 
  Pelzeln 
  has 
  given 
  it.

  ; 
  are 
  

   all 
  considered 
  synonyms 
  of 
  L. 
  infumata, 
  but 
  which 
  is 
  itself 
  a 
  

   synonym 
  of 
  L. 
  cana 
  Geoff., 
  this 
  last 
  being 
  considered 
  the 
  adult.
