  A 
  typical 
  Drillia, 
  with 
  somewhat 
  angular 
  wliorls, 
  and 
  numerous 
  

   rounded 
  longitudinal 
  plicae 
  ; 
  finely 
  spirally 
  lirate 
  tliroughout. 
  The 
  

   ])licse 
  are 
  rendered 
  conspicuous 
  by 
  the 
  light-brown 
  colouring 
  of 
  tlie 
  

   interstices. 
  Perhaps 
  the 
  nearest 
  species 
  is 
  D. 
  griffithi, 
  from 
  which 
  it 
  

   may 
  be 
  readily 
  distinguislied 
  by 
  its 
  much 
  more 
  delicate 
  sculpture.

  I 
  have 
  only 
  seen 
  a 
  single 
  individual 
  of 
  this 
  species. 
  It 
  was 
  found 
  

   in 
  the 
  collection 
  of 
  the 
  late 
  Admiral 
  Keppel 
  without 
  any 
  indication 
  

   of 
  its 
  habitat, 
  but 
  comes 
  very 
  likely 
  from 
  Sierra 
  Leone, 
  where 
  the 
  

   Admiral 
  collected 
  largely. 
  

  

  The 
  shell 
  is 
  one 
  of 
  striking 
  character, 
  the 
  whorls 
  being 
  unusually 
  

   concave, 
  with 
  a 
  stout 
  prominent 
  keel, 
  crossed 
  by 
  ntimerous 
  oblong 
  

   somewhat 
  oblique 
  white 
  tubercles 
  or 
  short 
  plicae, 
  which 
  are 
  rendered 
  

   more 
  conspicuous 
  by 
  a 
  brown 
  intersecting 
  spiral 
  line.
