  This 
  species, 
  as 
  pointed 
  out 
  by 
  Weinkauff 
  (p. 
  17), 
  is 
  the 
  same 
  as 
  

   MargineUa 
  hematita, 
  Kiener.

   Hab. 
  — 
  Island 
  of 
  Ticao, 
  Philippines. 
  

  

  This 
  is 
  a 
  very 
  small 
  MargineUa 
  belonging 
  to 
  the 
  same 
  group 
  as 
  

   M. 
  'pisum, 
  Reeve 
  and 
  others. 
  The 
  description 
  is 
  practically 
  useless, 
  no 
  

   mention 
  being 
  made 
  of 
  the 
  columellar 
  folds. 
  

  

  It 
  is 
  pyriformly 
  ovate, 
  pellucid, 
  glossy 
  ; 
  spire 
  almost 
  concealed 
  

   by 
  callus, 
  not 
  raised 
  ; 
  labrum 
  thickened 
  and 
  incurved, 
  whiter 
  than 
  the 
  

   rest 
  of 
  the 
  shell, 
  not 
  denticulated 
  at 
  the 
  edge; 
  columella 
  with 
  three 
  

   strong 
  folds 
  anteriorly, 
  and 
  four 
  smaller 
  tubercles 
  above. 
  The 
  front 
  

   fold 
  of 
  all 
  joins 
  the 
  labrum, 
  forming 
  the 
  anterior 
  end 
  of 
  the 
  very 
  

   narrow 
  aperture. 
  

  

  The 
  lip 
  is 
  described 
  by 
  Reeve 
  as 
  "rather 
  thin", 
  but 
  as 
  this 
  

   monograph 
  was 
  written 
  not 
  long 
  before 
  his 
  death, 
  such 
  errors 
  are 
  

   perhaps 
  pardonable, 
  and 
  allowance 
  may 
  be 
  made 
  for 
  the 
  very 
  

   unsatisfactory 
  character 
  of 
  the 
  whole 
  production.

  Undoubtedly 
  a 
  MargineUa, 
  and, 
  as 
  pointed 
  out 
  by 
  Tate 
  & 
  May, 
  

   evidently 
  the 
  same 
  as 
  M. 
  Stanislas, 
  under 
  which 
  name 
  Mr. 
  Tenison- 
  

   Woods 
  had 
  already 
  described 
  it 
  two 
  years 
  previously.

  As 
  indicated 
  by 
  Mr. 
  Justice 
  Gillies, 
  this 
  species 
  is 
  evidently 
  the 
  

   MargineUa 
  muscaria 
  of 
  Lamarck. 
  I 
  do 
  not 
  agree 
  with 
  Tryon 
  (p. 
  23) 
  

   in 
  considering 
  M. 
  formicula 
  the 
  same 
  as 
  nmscaria.
