  Aniboina 
  and 
  New 
  Guinea 
  groups 
  of 
  islands, 
  except 
  Wood- 
  

   lark 
  Is. 
  In 
  8. 
  australis 
  (Queensland) 
  and 
  S. 
  naias 
  (Wood- 
  

   lark 
  Is.) 
  the 
  cheek-teeth 
  are 
  linear 
  (as 
  in 
  Macroglossus 
  ; 
  p 
  4 
  , 
  

   m

  p

  , 
  and 
  m

  only 
  half 
  as 
  broad 
  as 
  long). 
  The 
  former 
  is 
  

   in 
  every 
  other 
  respect 
  similar 
  to 
  the 
  New 
  Guinea 
  race 
  

   (papuana) 
  of 
  S. 
  crassa, 
  whereas 
  S. 
  naias 
  differs 
  by 
  having 
  

   lost 
  the 
  small 
  posterior 
  molar 
  above 
  and 
  below 
  (cheek- 
  

   teeth 
  J). 
  

  

  The 
  five 
  subspecies 
  of 
  S. 
  crassa 
  differ 
  from 
  each 
  other 
  only 
  

   in 
  general 
  size 
  or 
  in 
  the 
  length 
  of 
  the 
  tooth-rows. 
  Speci- 
  

   mens 
  from 
  New 
  Guinea 
  and 
  the 
  Aru 
  Islands 
  (S. 
  c.

   are 
  of 
  medium 
  size 
  ; 
  those 
  from 
  the 
  Key 
  Islands 
  (S. 
  c. 
  key- 
  

   ensis, 
  subsp.

  have 
  somewhat 
  shorter 
  tooth-rows, 
  those 
  

   from 
  the 
  Bismarck 
  Archipelago 
  (S. 
  c. 
  finschi) 
  average 
  a 
  

   little 
  smaller

  finally, 
  east 
  (Trobriand

   Islands

  (Amboina

   S.

  of

  the 
  size 
  of 
  the 
  animals 
  

   is 
  noticeably 
  increased, 
  though 
  not 
  more 
  so 
  but 
  that 
  there 
  is 
  

   still 
  no 
  absolutely 
  hard-and-fast 
  line 
  between 
  papuana 
  and 
  

   crassa, 
  nor 
  between
