  This 
  small 
  species 
  is 
  of 
  very 
  different 
  character 
  to 
  the 
  others 
  at 
  

   present 
  associated 
  with 
  it, 
  though 
  when 
  examined 
  with 
  ahigh])ower 
  

   it 
  will 
  be 
  seen 
  to 
  possess 
  many 
  kindred 
  qualities 
  — 
  the 
  l)eautifully 
  

   cancellate 
  ochreoiis

  incrassate 
  riblets,

  An 
  Arctic 
  species, 
  named 
  Defrancia

  by

  is, 
  

   judging 
  by 
  the 
  figure, 
  of 
  much 
  the 
  same 
  character.

  This 
  is 
  comparable 
  with 
  Paphnella 
  vestalis, 
  Hedley, 
  an 
  e'lually 
  

   exquisite 
  form, 
  the 
  sinus 
  in 
  both 
  is 
  non-existent, 
  and 
  the 
  ornamenta- 
  

   tion 
  and 
  shape 
  very 
  similar. 
  Our 
  species 
  is 
  the 
  coarser 
  of 
  the 
  two, 
  

   and 
  the 
  whorls 
  more 
  sharply 
  angled.
