  Mr. 
  O. 
  Thomas 
  on 
  

  

  Of 
  the 
  two 
  small 
  voles 
  of 
  t!iis 
  region 
  I 
  assigned, 
  in 
  my 
  

   ])aper 
  on 
  the 
  Carrnthers 
  mammals, 
  the 
  name 
  evei'smanni, 
  

   Poliakoff, 
  to 
  the 
  Microtus, 
  and 
  not 
  to 
  the 
  Stenoci'am'iis, 
  on 
  

   the 
  ground 
  that 
  Biichner's 
  figure 
  of 
  the 
  skull 
  clearly 
  indicated 
  

   a 
  Microtns 
  and 
  that, 
  as 
  he 
  mentions 
  Polinkoft^s 
  original 
  

   specimens, 
  this 
  tignre 
  miglit 
  be 
  supposed 
  to 
  be 
  taken 
  from 
  

   one 
  of 
  them. 
  Whether 
  Buchner''s 
  Przwalski 
  specimens 
  

   were 
  of 
  the 
  same 
  form 
  or 
  not 
  did 
  not 
  affect 
  the 
  question. 
  

  

  (Since 
  I 
  wrote, 
  however, 
  Mr. 
  Hollister 
  *, 
  in 
  agreement 
  

   with 
  Kashtcheidio, 
  has 
  again 
  put 
  eversmanni 
  into 
  Steiio- 
  

   croniuSj 
  and 
  I 
  therefore 
  now 
  accept 
  his 
  conclusion, 
  at 
  least 
  

   until 
  an 
  expert 
  examination 
  can 
  be 
  made 
  of 
  tlie 
  types

  This 
  series 
  shows 
  well 
  how 
  the 
  colour 
  intensifies 
  as 
  age 
  

   advances, 
  the 
  younger 
  specimens 
  being 
  greyish 
  buff, 
  while 
  

   the 
  older 
  ones 
  attain 
  a 
  rich 
  cinnamon. 
  

  

  I 
  can 
  find 
  no 
  tangible 
  difference 
  between 
  the 
  Djarkent 
  

   examples 
  and 
  the 
  three 
  original 
  specimens 
  obtained 
  by 
  

   Mr. 
  Oarruthers 
  on 
  the 
  southern 
  slopes 
  of 
  the 
  Barlik 
  Mountains. 
  

  

  By 
  the 
  help 
  of 
  this 
  series, 
  however, 
  I 
  am 
  now 
  able 
  to 
  

   distinguish 
  the 
  skull 
  of 
  ursulus 
  from 
  that 
  of
