  distinguishable 
  by 
  its 
  cinnamon-waslied 
  sides

   rump

  the 
  more 
  blackish 
  backs 
  to 
  its

  Pseudalopex 
  smithersi, 
  sp. 
  n. 
  

  

  Ps. 
  culpceus 
  group, 
  but 
  the 
  body 
  reddish 
  throughout. 
  

  

  Size 
  apparently 
  rather 
  less 
  than 
  in 
  culpceus. 
  Fur 
  soft 
  and 
  

   thick, 
  not 
  very 
  long. 
  Colour 
  wholly 
  unlike 
  that 
  of 
  any 
  

   known 
  Pseudalopex, 
  owing 
  to 
  the 
  black 
  on 
  the 
  tips 
  of 
  the 
  

   hairs, 
  which 
  forms 
  so 
  prominent 
  a 
  feature 
  in 
  the 
  colouring 
  of 
  

   other 
  species, 
  being 
  here 
  replaced 
  by 
  rich 
  ochraceous 
  red, 
  

   the 
  underfur 
  being 
  still 
  creamy 
  buff 
  terminally 
  and 
  slaty 
  

   basally. 
  On 
  the 
  tail 
  alone 
  the 
  terminal 
  brush 
  is, 
  as 
  usual, 
  

   black, 
  the 
  bases 
  of 
  the 
  hairs 
  buffy, 
  and 
  the 
  hairs 
  of 
  the 
  caudal 
  

   gland 
  are 
  black 
  terminally 
  and 
  white 
  for 
  their 
  basal 
  two- 
  

   thirds; 
  the 
  hairs 
  of 
  the 
  rest 
  of 
  the 
  tail 
  tipped 
  with 
  rich 
  

   ferruginous. 
  As 
  a 
  result 
  we 
  have 
  an 
  animal 
  which 
  is 
  bright 
  

   reddish, 
  head, 
  body, 
  and 
  limbs, 
  though, 
  owing 
  to 
  the 
  buffy 
  

   underfur, 
  the 
  colour 
  is 
  not 
  as 
  strong 
  as 
  in 
  some 
  of 
  the 
  purely 
  

   red 
  Canidae. 
  Under 
  surface 
  dull 
  buffy 
  whitish 
  on 
  throat 
  

   and 
  lower 
  belly, 
  deeper 
  and 
  more 
  pinkish 
  buffy 
  on 
  the 
  chest 
  

   and 
  sides 
  of 
  belly. 
  Chin 
  with 
  a 
  slight 
  darkening, 
  as 
  in 
  

   culpceus, 
  not 
  a 
  definite 
  black 
  patch 
  as 
  in 
  the 
  azarica 
  group; 
  

   nor 
  is 
  there 
  any 
  trace 
  of 
  a 
  dark 
  patch 
  on 
  the 
  back 
  of 
  the 
  

   thighs. 
  

  

  Dimensions, 
  owing 
  to 
  the 
  specimen 
  being 
  a 
  made-up 
  

   tanned 
  skin, 
  not 
  able 
  to 
  be 
  taken, 
  but 
  the 
  size 
  appears 
  to 
  be 
  

   somewhat 
  less 
  than 
  in 
  Ps. 
  culpceus. 
  

  

  Hah.

  de

  This 
  most 
  remarkable 
  mountain-fox 
  is 
  closely 
  related 
  to 
  

   Pseudalope.v 
  cidpceus, 
  but 
  is 
  at 
  once 
  distinguished 
  from 
  that 
  

   and 
  every 
  other 
  member 
  of 
  the 
  genus 
  by 
  the 
  replacement 
  of 
  

   the 
  grizzled 
  black 
  and 
  white 
  of 
  the 
  body 
  by 
  rich 
  ferruginous.
