  Mah. 
  — 
  Japan 
  (Stearns). 
  

  

  A 
  fine 
  and 
  very 
  distinct 
  species, 
  the 
  columellar 
  area 
  suffused 
  often 
  

   with 
  pink, 
  and 
  otherwise 
  variegated 
  with 
  brown 
  streaked 
  painting. 
  

   Small 
  papillae 
  present 
  on 
  the 
  columellar 
  area. 
  As 
  the 
  name 
  implies, 
  

   it 
  is 
  a 
  massive 
  shell, 
  proportionately 
  speaking, 
  the 
  ribs 
  blunt 
  and 
  

   rounded, 
  rather 
  after 
  the 
  fashion 
  of 
  M. 
  oniscus 
  (L.). 
  There 
  is 
  a 
  deep 
  

   sulcation 
  posteriorly. 
  In 
  general 
  form 
  this 
  species, 
  separated 
  .by 
  

   Hanley 
  because 
  of 
  the 
  above-mentioned 
  sulcus, 
  serves 
  to 
  unite 
  

   typical 
  Mortem 
  with 
  Oniscidia.

  The 
  unique 
  type 
  in 
  the 
  British

  is 
  not 
  quite 
  adult. 
  

  

  The 
  ribs 
  are 
  17, 
  close, 
  echinate-spinulose, 
  the 
  penultimate 
  whorl 
  

   also 
  bearing

  short, 
  regular

  Hah. 
  — 
  China. 
  

  

  Much 
  larger 
  in 
  all 
  its 
  parts 
  than 
  the 
  very 
  similar 
  cancellatum 
  ; 
  

   indeed. 
  Reeve 
  has 
  figured 
  this 
  species 
  under 
  that 
  name. 
  This 
  was 
  

   at 
  all 
  events 
  Mr. 
  Edgar 
  Smith's 
  fixed 
  opinion 
  — 
  and 
  that 
  specimen, 
  

   being 
  from 
  the 
  Cumingian 
  Collection, 
  is, 
  doubtless, 
  in 
  the 
  Britisli 
  

   Museum. 
  I 
  have 
  a 
  very 
  fine 
  example, 
  formerly 
  in 
  Mr. 
  J. 
  J. 
  

   Macandrew's 
  possession, 
  75 
  X 
  40 
  mm. 
  Its 
  principal 
  points 
  of 
  

   distinction 
  seem 
  to 
  lie 
  in 
  its 
  size, 
  more 
  frequent 
  longitudinal 
  costse, 
  

   being 
  18 
  against 
  12 
  in 
  its 
  smaller 
  ally, 
  special 
  ridges 
  thicker 
  and 
  

   more 
  markedly 
  imbricate, 
  columellar 
  area 
  more 
  porcellanous 
  in 
  

   consistency, 
  and 
  shining 
  white, 
  papillce 
  not 
  so 
  numerous 
  and 
  close.
