  Two 
  species 
  are 
  here 
  recorded 
  which 
  have 
  been 
  referred 
  to 
  the 
  

   genus 
  Lasiopyga: 
  Simla 
  diana 
  and 
  5. 
  cethiops. 
  The 
  first 
  is 
  

   the 
  well 
  known 
  Monkey, 
  Lasiopyga 
  diana 
  from 
  Liberia, 
  the 
  

   other, 
  however, 
  is 
  not 
  so 
  easily 
  determined. 
  De 
  Winton 
  (1. 
  c.) 
  

   considers 
  it 
  to 
  be 
  the 
  species 
  afterwards 
  called 
  by 
  Desmarest 
  

   (1. 
  c.) 
  C. 
  griseoviridis 
  from 
  the 
  region 
  of 
  the 
  Upper 
  Nile, 
  

   Abyssinia, 
  Sennaar 
  and 
  Kordofan, 
  but 
  Linnaeus' 
  description, 
  

   which 
  was 
  evidently 
  taken 
  from 
  Hasselquist's, 
  for 
  it 
  is 
  doubt- 
  

   ful 
  if 
  he 
  ever 
  saw 
  a 
  specimen, 
  presents 
  certain 
  difficulties 
  that 
  

   make 
  it 
  more 
  than 
  probable 
  some 
  other 
  animal 
  than 
  the 
  one 
  

   from 
  the 
  White 
  Nile 
  was 
  intended. 
  The 
  difficulty 
  is 
  met 
  with 
  

   in 
  the 
  sentence 
  "Cauda 
  tecta, 
  subtus 
  ferruginea." 
  Now 
  the 
  

   tail 
  of 
  the 
  White 
  Nile 
  species 
  is 
  speckled 
  grayish 
  above, 
  and 
  

   white 
  beneath, 
  and 
  this 
  fact 
  would 
  seem 
  at 
  once 
  to 
  compel 
  us 
  

   to 
  believe 
  that 
  cethiops 
  Linn., 
  is 
  not 
  the 
  same. 
  The 
  Linnaean 
  

   species 
  may 
  possibly 
  be 
  L. 
  ascanius 
  which 
  has 
  a 
  red 
  tail 
  above 
  

   and 
  below 
  except 
  at 
  the 
  base, 
  or 
  L. 
  cephus 
  of 
  which 
  in 
  the 
  12th 
  

   edition 
  he 
  makes 
  a 
  variety. 
  That 
  it 
  belongs 
  to 
  one 
  of 
  the 
  

   Petaurista, 
  or 
  so-called 
  Mthiops 
  groups 
  is 
  most 
  likely, 
  but 
  its 
  

   determination 
  is 
  not 
  easy 
  of 
  accomplishment, 
  and 
  all 
  that 
  can 
  

   be 
  said 
  with 
  any 
  degree 
  of 
  certainty 
  is, 
  that, 
  while 
  in 
  some 
  

   degree 
  it 
  resembles 
  C. 
  griseoviridis 
  Desm., 
  it 
  is 
  not 
  that 
  

   species, 
  nor 
  can 
  it 
  be 
  referred 
  to 
  any 
  known 
  species, 
  and 
  must 
  

   therefore 
  take 
  a 
  place 
  among 
  the 
  undeterminable 
  forms.

  In 
  this 
  the 
  12th 
  edition 
  of 
  Linnaeus' 
  work 
  under 
  Simia, 
  four 
  

   species, 
  now 
  placed 
  in 
  Lasiopyga, 
  are 
  given, 
  but 
  among 
  them, 
  

   cethiops, 
  of 
  the 
  1758 
  edition, 
  as 
  a 
  species 
  is 
  not 
  found. 
  They 
  are 
  

   S. 
  diana; 
  (S.) 
  sabcea 
  undeterminable; 
  (S.) 
  cephus; 
  and 
  (S\) 
  

   nictitans 
  first 
  described. 
  Under 
  (S.) 
  cephus 
  var. 
  B, 
  is 
  (S.) 
  

   cethiops, 
  but 
  in 
  the 
  diagnosis 
  no 
  mention 
  is 
  made 
  of 
  the 
  color 
  of 
  

   the 
  tail, 
  simply 
  caudata 
  imberbis, 
  showing 
  it 
  was 
  a 
  long 
  tailed 
  

   monkey. 
  Evidently 
  Linnaeus 
  was 
  not 
  certain 
  of 
  the 
  distinctness 
  

   of 
  his 
  S. 
  cethiops, 
  and 
  so 
  in 
  his 
  edition 
  reduced 
  it 
  to 
  a 
  variety 
  of 
  

   a 
  reddish 
  tailed 
  species.
