  The 
  Briiish 
  Museum 
  series 
  of 
  Asiatic 
  polecats 
  shows 
  these 
  

   animals 
  to 
  be 
  by 
  no 
  means 
  so 
  unvarying 
  in 
  colour 
  as 
  might 
  

   be 
  supposed 
  from 
  Mr. 
  Hollister's 
  statement 
  as 
  to 
  their 
  con- 
  

   stancy. 
  In 
  two 
  cases 
  sets 
  from 
  the 
  same 
  place 
  differ 
  con- 
  

   siderably 
  inter 
  se, 
  as^ 
  for 
  instance, 
  in 
  the 
  brown 
  or 
  white 
  

   colour 
  of 
  the 
  crown, 
  and 
  there 
  is, 
  of 
  course, 
  always 
  a 
  wide 
  

   difference 
  between 
  winter 
  and 
  summer 
  specimens.

  Three 
  males, 
  in 
  winter 
  pelage. 
  

  

  In 
  addition 
  to 
  these 
  three 
  specimens 
  I 
  have 
  before 
  me 
  a 
  

   female 
  in 
  winter 
  pelage 
  from 
  Przewalsk 
  (Coll. 
  Kutsenko) 
  and 
  

   the 
  type, 
  in 
  summer 
  pelage, 
  from 
  Mt. 
  Kara-Karyk, 
  Ferghana 
  

   (Coll. 
  Bare}). 
  The 
  last 
  was 
  said 
  by 
  its 
  collector 
  to 
  be 
  a 
  

   male, 
  a 
  statement 
  I 
  published 
  when 
  describing 
  the 
  subspecies 
  ; 
  

   but 
  while 
  the 
  skin 
  shows 
  no 
  external 
  evidence 
  of 
  sex, 
  its 
  

   agreement 
  in 
  size 
  and 
  skull- 
  characters 
  with 
  Mr. 
  Kutsenko's 
  

   female 
  is 
  so 
  close 
  that 
  I 
  am 
  now 
  disposed 
  to 
  think 
  that 
  it 
  also 
  

   is 
  a 
  female. 
  

  

  This 
  mistake, 
  to 
  which 
  I 
  regret 
  that 
  I 
  gave 
  currency, 
  may 
  

   result 
  in 
  the 
  invalidation 
  of 
  Mr. 
  Hollister's 
  '■^Mustela 
  lijmani,^^ 
  

   described 
  on 
  a 
  male 
  so 
  mucli 
  larger 
  than 
  the 
  Ferghana 
  speci- 
  

   men 
  that 
  Mr, 
  HoUister 
  appeared 
  to 
  be 
  quite 
  justified 
  in 
  

   distinguishing 
  it, 
  on 
  the 
  assumption 
  that 
  the 
  sexes 
  were 
  the 
  

   same. 
  Further 
  summer 
  skins 
  of 
  both 
  forms 
  will, 
  however, 
  

   be 
  needed 
  before 
  this 
  question 
  can 
  be 
  definitely 
  settled.
