  marked 
  

   as 
  subspecies 
  ( 
  !),

  the 
  only 
  ones 
  known 
  to 
  the 
  

   Author, 
  (although 
  L. 
  sannio 
  (Thos.), 
  was 
  represented 
  in 
  the 
  

   British 
  Museum 
  Collection 
  by 
  the 
  type), 
  and 
  a 
  list 
  of 
  the 
  

   described 
  species 
  is 
  given, 
  or 
  taken 
  from 
  Herr 
  Matschie's 
  paper 
  

   on 
  the 
  genus. 
  Mr. 
  Pocock's 
  method 
  of 
  employing 
  subspecific 
  

   names 
  is 
  somewhat 
  perplexing, 
  for 
  it 
  is 
  generally 
  understood 
  

   by 
  Naturalists 
  that 
  a 
  subspecies 
  can 
  only 
  be 
  properly 
  established 
  

   when 
  there 
  are 
  intergrades 
  between 
  it 
  and 
  a 
  closely 
  related 
  

   species. 
  Now 
  nearly 
  all 
  the 
  recognized 
  subspecies 
  in 
  this 
  

   paper, 
  save 
  perhaps 
  L. 
  nigripes 
  (Du 
  Chaillu), 
  and 
  which 
  is 
  

   intermediate 
  between 
  L. 
  grayi 
  and 
  L. 
  pogonias 
  in 
  only 
  one 
  

   particular, 
  a 
  little 
  more 
  black 
  on 
  the 
  back, 
  and 
  L. 
  ellenbecki 
  

   which 
  is 
  the 
  same 
  as 
  L. 
  hilgerti, 
  have 
  no 
  intermediates, 
  and
