  Perhaps 
  not 
  full 
  grown, 
  this 
  interesting 
  little 
  species 
  possesses 
  

   a 
  peculiarity 
  in 
  form, 
  being 
  in 
  miniature 
  much 
  like 
  a 
  3Iitra 
  of 
  the 
  

   section 
  Turricula 
  both 
  in 
  form 
  and 
  disposition 
  of 
  coloration 
  pattern, 
  

   the 
  triple 
  band 
  around 
  the 
  body-whorl 
  being 
  notable. 
  The 
  Avhorls 
  

   are 
  all 
  considerably 
  suturally 
  impressed 
  and 
  ventricose, 
  multicostate, 
  

   and 
  spirally 
  finely 
  Urate.

   alhata,

  had 
  best 
  be 
  considered

  An 
  interesting 
  form, 
  of 
  which 
  only 
  one 
  specimen 
  was 
  obtained. 
  It 
  

   seems 
  to 
  me 
  sufiSciently 
  distinct, 
  however, 
  from 
  the 
  known 
  recent 
  

   species 
  to 
  attempt 
  a 
  description. 
  The 
  broadened 
  fusiform 
  contour, 
  

   conspicuous 
  central 
  acute 
  angle 
  in 
  the 
  lower 
  whorls, 
  thickish 
  oblique 
  

   ribs, 
  characterize 
  it 
  fully, 
  the 
  only 
  ally 
  known 
  to 
  me 
  being 
  scalata, 
  

   Souverbie, 
  from 
  Xew 
  Caledonia, 
  with 
  which 
  Tryon 
  merges 
  melayiostoma, 
  

   Garrett, 
  from 
  Fiji, 
  and 
  angicostata, 
  Reeve, 
  from 
  the 
  same 
  locality. 
  

   These 
  all 
  seem, 
  however, 
  to 
  differ 
  considerably.

  his
