  and 
  below 
  

   these 
  by 
  two 
  or 
  three

  fms., 
  and 
  Cerf 
  Island, 
  Masearenes, 
  in 
  10 
  fms. 
  

  

  This 
  species 
  bears 
  some 
  resemblance 
  to 
  C. 
  articulatum, 
  Adams 
  

   and 
  Eeeve, 
  especially 
  as 
  regards 
  the 
  aperture. 
  It 
  may 
  bo 
  distin- 
  

   guished 
  by 
  the 
  prominent 
  row 
  of 
  acute 
  nodules 
  just 
  below 
  the 
  

   suture, 
  the 
  corresponding 
  series 
  in 
  C. 
  articulatum 
  being 
  smaller, 
  so 
  

   that 
  the 
  whorls 
  at 
  this 
  part 
  are 
  narrower 
  than 
  below, 
  whilst, 
  on 
  the 
  

   contrary, 
  in 
  the 
  present 
  species 
  they 
  are 
  widest.

  This 
  is 
  a 
  most 
  curious 
  species, 
  on 
  account 
  of 
  the 
  prominent 
  canal 
  

   behind 
  the 
  aperture.
