  Classification 
  of 
  marmosets 
  treated 
  here 
  places 
  the 
  most 
  specialized 
  

   genus 
  Leontocebus 
  last. 
  Hairy-faced 
  tamarins, 
  subgenus 
  Tamarin, 
  

   of 
  the 
  genus 
  Marikina, 
  are 
  most 
  generalized 
  as 
  well 
  as 
  most 
  diversified 
  

   and 
  widely 
  distributed. 
  They 
  are 
  listed 
  first. 
  The 
  bare-faced 
  

   tamarins, 
  Oedipomidas 
  (subgenus) 
  and 
  Marikina 
  (sensu 
  stricto), 
  are 
  

   nearly 
  related 
  but 
  divergent 
  branches 
  of 
  the 
  common 
  tamarin 
  stock.
