  Compared 
  with 
  M. 
  fairhanki, 
  Tfevill, 
  by 
  the 
  authors, 
  and 
  yet 
  

   placed 
  in 
  a 
  different 
  genus. 
  The 
  fact 
  is 
  that 
  Manff 
  ilia 
  and 
  ClathureUa, 
  

   though 
  distinct 
  enough 
  in 
  tlie 
  extremes, 
  are 
  yet 
  so 
  linked 
  by 
  species 
  

   bearing 
  common 
  characteristics 
  as 
  to 
  be 
  often 
  impossible 
  to 
  define 
  

   satisfactorily. 
  None 
  of 
  the 
  specimens 
  I 
  have 
  seen 
  are 
  apically 
  

   perfect, 
  and 
  the 
  authors 
  do 
  not 
  mention 
  their 
  apical 
  characters; 
  but 
  

   I 
  consider 
  tliis 
  species 
  allied 
  to 
  others 
  now 
  placed 
  in 
  Mangilia, 
  and 
  

   class 
  it 
  there 
  accordingly.

  Reeve's 
  figure 
  of 
  the 
  type 
  exhibits 
  a 
  more 
  attenuate 
  

   shell 
  than 
  ours, 
  with 
  produced 
  canal, 
  yet 
  we 
  have 
  compared 
  it 
  with 
  

   our 
  specimens 
  closely 
  at 
  tbe 
  British 
  Museum, 
  and 
  are 
  satisfied 
  as 
  to 
  

   their 
  identity. 
  The 
  original 
  specimen 
  came 
  from 
  tbe 
  Straits 
  of 
  

   Macassar, 
  Celebes, 
  and 
  was 
  dredged

  It

  the

   apical 
  whorls
