  This 
  water-shrew 
  is 
  very 
  like 
  the 
  N.fodiens 
  of 
  Northern 
  

   Europe, 
  but 
  would 
  seem 
  to 
  be 
  sufHcientlj 
  distinguished 
  by 
  

   the 
  characters 
  above 
  described. 
  Owing- 
  to 
  its 
  long 
  rich 
  fur^ 
  

   strongly 
  contrasted 
  coloration, 
  and 
  well-marked 
  white 
  caudal 
  

   fringe 
  it 
  is 
  even 
  more 
  beautiful 
  than 
  most 
  examples 
  of 
  the 
  

   European 
  animal.

  Although 
  with 
  rather 
  more 
  prominent 
  front 
  incisors 
  than 
  

   ordinary 
  araneus, 
  and 
  thus 
  leading 
  on 
  towards 
  the 
  species 
  

   now 
  to 
  be 
  described, 
  these 
  shrews 
  can 
  be 
  matched 
  in 
  this 
  

   respect 
  by 
  some 
  Scandinavian 
  specimens, 
  and 
  may 
  therefore 
  

   be 
  assigned 
  to 
  S. 
  araneics. 
  On 
  the 
  other 
  hand, 
  the 
  shrew 
  of 
  

   the 
  same 
  group 
  from 
  the 
  Thian-shan 
  should 
  certainly 
  bear 
  a 
  

   special 
  name. 
  Indeed, 
  I 
  distinguished 
  and 
  named 
  it 
  some 
  

   years 
  ago, 
  but 
  its 
  description 
  seems 
  never 
  to 
  have 
  been 
  

   published. 
  

  

  Sorex 
  asper,

  n. 
  

  

  Allied 
  to 
  S. 
  araneus, 
  but 
  the 
  upper 
  incisors 
  and 
  unicuspids 
  

   much 
  enlarged. 
  

  

  Colour 
  brown, 
  no 
  tricolor 
  pattern 
  perceptible. 
  Under 
  

   surface 
  of 
  a 
  summer 
  specimen 
  also 
  brown, 
  little 
  lighter 
  than 
  

   the 
  upper 
  colour; 
  of 
  a 
  winter 
  specimen 
  hoary 
  grey 
  with 
  

   slaty 
  bases 
  to 
  the 
  hairs. 
  Fur 
  of 
  summer 
  specimen

  of 
  

   winter 
  specimen 
  7*5 
  mm. 
  in 
  length. 
  

  

  Skull 
  like 
  that 
  of 
  S. 
  araneus, 
  but 
  the 
  muzzle 
  longer. 
  

  

  Anterior 
  upper 
  incisors 
  large, 
  heavy, 
  much 
  projected 
  

   forwards, 
  their 
  upper 
  front 
  profile 
  starting 
  forwards 
  nearly 
  

   horizontally 
  from 
  the 
  bone 
  supporting 
  them, 
  instead 
  of 
  being 
  

   continued 
  in 
  the 
  same 
  slanting 
  line 
  as 
  the 
  profile 
  of 
  the 
  

   bone. 
  Unicuspids 
  very 
  large 
  and 
  heavy, 
  the 
  combined 
  

   length 
  of 
  the 
  first 
  three 
  2'3 
  mm., 
  their 
  breadth 
  especially 
  

   great 
  in 
  proportion. 
  Molars 
  not 
  larger 
  than 
  in 
  araneus, 
  so 
  

   that 
  the 
  muzzle 
  is 
  longer 
  in 
  proportion 
  than 
  in 
  that 
  species.
