  from 
  

  

  in 
  his 
  Catalogue, 
  a 
  monograph 
  which 
  has 
  entirely 
  revolu- 
  

   tionized 
  our 
  knowledge 
  o£ 
  the 
  group. 
  The 
  fact 
  also 
  that 
  the 
  

   genus 
  is 
  named 
  after 
  Dr. 
  G. 
  E. 
  Dobson 
  creates 
  a 
  suitable 
  

   juxtaposition 
  of 
  two 
  names 
  that 
  must 
  always 
  be 
  historical 
  in 
  

   connection 
  with 
  the 
  classification 
  of 
  the 
  Chiroptera.

  Allied

  K.

  with 
  which 
  it 
  shares 
  the 
  

   varied 
  Vizcacha- 
  or 
  Lagidium-Vike 
  fur, 
  strongly 
  spotted 
  con- 
  

   dition 
  of 
  wings, 
  and 
  coalescence 
  of 
  the 
  inner 
  with 
  the 
  main 
  

   cusp 
  of 
  p^, 
  but 
  distinguished 
  by 
  the 
  further 
  coalescence 
  of 
  

   the 
  corresponding 
  cusps 
  in 
  the 
  lower 
  jaw 
  and 
  by 
  its 
  greater 
  

   size.

  Fur 
  long, 
  hairs 
  of 
  back

  10 
  mm.

   length. 
  General 
  colour 
  above 
  irregulaily 
  varied 
  drab-grey, 
  

   singularly 
  like 
  thatof 
  Lagi'dium, 
  and 
  in 
  this 
  way 
  corresponding 
  

   with 
  that 
  of 
  A^.

  and 
  differing 
  from

  of 
  the 
  more 
  

   nmlovmly 
  coloured 
  jy. 
  pajnianus. 
  Dorsal 
  streak 
  beginning 
  

   at 
  withers, 
  rather 
  well 
  marked 
  considering 
  the 
  waviness 
  of 
  

   the 
  hair, 
  but 
  not 
  nearly 
  so 
  much 
  so 
  as 
  in

  surface 
  drabby

  Ears, 
  arms, 
  and 
  digits 
  profusely 
  

   spotted 
  with 
  yellow, 
  more 
  so 
  than 
  in 
  the 
  allied 
  species; 
  wing- 
  

   membranes 
  also 
  much 
  mottled 
  with 
  yellow. 
  

  

  Skull 
  much 
  larger 
  and 
  heavier 
  than 
  that 
  of

   slightly 
  exceeding 
  in 
  size 
  the 
  largest 
  skulls 
  of 
  N.papuanus. 
  

  

  Teeth 
  agreeing 
  with 
  those 
  of 
  N.

  and 
  minutus 
  in 
  the 
  

   fusion 
  of 
  the 
  inner 
  with 
  the 
  outer 
  cusp 
  of

  but 
  differing

  This 
  species 
  curiously 
  bears 
  out 
  Dr. 
  Andersen's 
  arrange- 
  

   ment 
  of 
  the 
  genus 
  by 
  the 
  correlation 
  of 
  its 
  wavy 
  fur 
  with 
  

   the 
  structure 
  of 
  p^, 
  just 
  as 
  in 
  his 
  group 
  '* 
  b^/' 
  consisting 
  of 
  

   A^. 
  minutus 
  and 
  varius. 
  Then, 
  being 
  even 
  more 
  mottled 
  and 
  

   spotted, 
  it 
  equally 
  goes 
  further 
  in 
  dentition,

  its 
  p^
