  The 
  type-specimens 
  collected 
  by 
  Sir 
  Lewis 
  Pelly 
  are 
  in 
  poor 
  

   condition, 
  but 
  I 
  have 
  but 
  little 
  doubt 
  are 
  the 
  same 
  as 
  my 
  callutephati 
  a, 
  

   described 
  twenty 
  years 
  later. 
  Nuclear 
  whorls 
  smooth, 
  second 
  and 
  

   third 
  carinate. 
  The 
  double 
  row 
  of 
  nodules 
  encircling 
  the 
  whorls 
  at 
  

   the 
  ribs, 
  and 
  the 
  very 
  narrow 
  cylindrical 
  contour, 
  distinguish 
  this 
  

   interesting 
  little 
  shell. 
  There 
  is, 
  however, 
  a 
  near 
  ally 
  in 
  the 
  same 
  

   dredging, 
  wliich 
  I 
  have 
  described 
  in 
  this 
  paper 
  under 
  the 
  name 
  of 
  

   M.

  Allied

  but 
  with 
  much 
  thickened

   lip 
  and 
  abbreviate 
  contour. 
  I 
  now 
  doubt 
  its 
  being 
  a 
  Lienardia 
  

   (= 
  Glyphostoma), 
  the 
  columella 
  is 
  plain 
  and 
  smooth, 
  and 
  the 
  general 
  

   ' 
  facies 
  ' 
  that 
  of 
  the 
  typical 
  genus. 
  It 
  has 
  only 
  occurred 
  in 
  small 
  

   quantity.

  A

  M. 
  falvocincta, 
  Nevill, 
  and 
  pellyi,

   but 
  differing 
  in 
  the 
  absence 
  of 
  fine 
  spiral 
  striae 
  over 
  the 
  whorls, 
  which 
  

   both 
  these 
  species 
  possess. 
  Tiie

  pure 
  

   white

  oaken-brown.

  Evidently 
  not 
  a 
  Clathurella, 
  but, 
  like 
  M. 
  alhata, 
  Sm., 
  which 
  is 
  an 
  

   ally, 
  we 
  are 
  not 
  sure 
  about 
  its 
  true 
  generic 
  position. 
  It 
  is 
  very 
  

   abundant 
  in 
  the 
  latter 
  dredging 
  mentioned, 
  whence 
  came 
  so 
  many 
  

   novelties. 
  Tlie 
  figure 
  quoted 
  hardly 
  does 
  it 
  justice, 
  the 
  outer 
  lip 
  not 
  

   being 
  perfect 
  in 
  the 
  specimen 
  figured. 
  The 
  sinus 
  is 
  wide, 
  but 
  

   shallow, 
  the 
  longitudinal 
  costae 
  of 
  the 
  body-whorl 
  numbering 
  eight. 
  

   The 
  shell 
  is 
  a 
  pure 
  white 
  in 
  all 
  the 
  specimens 
  examined. 
  It 
  

   appears 
  most 
  nearly 
  allied 
  to 
  Pletirotoma 
  turris, 
  Reeve 
  (Conch. 
  

   Icon., 
  vol. 
  i, 
  pi. 
  xxxvii, 
  fig. 
  344). 
  This 
  is 
  an 
  olive-brown 
  species, 
  

   reported 
  also 
  from 
  the 
  Persian 
  Gulf 
  district, 
  first 
  called 
  ^/ryoc^a 
  by 
  

   Reeve, 
  an 
  already 
  occupied 
  name, 
  fi'om, 
  to 
  quote 
  his 
  words, 
  "the 
  

   strong 
  ribs 
  continuing 
  one 
  under 
  the 
  other, 
  and 
  providing 
  a 
  peculiar 
  

   pagoda-like 
  form." 
  'This 
  character, 
  however, 
  does 
  not 
  seem
