  n.sp. 
  

   Testa 
  turbinata, 
  mediocriter 
  obesa, 
  albida, 
  luteo-fusco 
  tribalteata, 
  

   flammulis 
  longitudinalibus

  Francis 
  Bay,

  Africa. 
  

  

  A 
  rather 
  gaily- 
  coloured 
  Cone, 
  with 
  three 
  rather 
  broad 
  bands 
  of 
  

   yellowish 
  brown 
  and 
  irregularly 
  formed 
  flames 
  of 
  a 
  darker 
  colour. 
  

   The 
  spire 
  in 
  the 
  normal 
  form 
  is 
  somewhat 
  obtuse, 
  and 
  but 
  little 
  

   raised, 
  with 
  the 
  whorls 
  graduated, 
  smooth, 
  and 
  concave 
  at 
  the 
  top. 
  

   The 
  body-whorl 
  is 
  slightly 
  rounded 
  at 
  the 
  angle, 
  which, 
  however, 
  is 
  

   fairly 
  prominent, 
  convex 
  at 
  the 
  sides, 
  and 
  tapering 
  towards 
  the 
  base. 
  

   In 
  addition 
  to 
  the 
  colour-bands 
  and 
  flames 
  the 
  type-specimen 
  has 
  here 
  

   and 
  there 
  a 
  few 
  minute 
  brown 
  spots. 
  

  

  The 
  second 
  specimen 
  is 
  an 
  abnormality; 
  its 
  spire 
  being 
  considerably 
  

   raised 
  and 
  irregularly 
  gradate 
  ; 
  in 
  this 
  the 
  small 
  brown 
  spots 
  are 
  

   much 
  more 
  numerous. 
  

  

  The 
  only 
  two 
  specimens 
  I 
  have 
  seen 
  of 
  this 
  species 
  were 
  submitted 
  

   to 
  me 
  by 
  Dr. 
  H. 
  Becker, 
  of 
  Grahamstown, 
  after 
  whom 
  I 
  have 
  pleasure 
  

   in 
  naming 
  it. 
  

  

  Dr. 
  Becker 
  also 
  sent 
  me 
  for 
  comparison 
  specimens 
  of 
  Comis 
  lautus, 
  

   Reeve, 
  from 
  the 
  same 
  localitj^ 
  some 
  of 
  the 
  specimens 
  bearing 
  a 
  slight 
  

   resemblance 
  to 
  the 
  new 
  species, 
  but 
  differing 
  considerably 
  from 
  it 
  in 
  

   form 
  and 
  in 
  the 
  character 
  of 
  the 
  spire.
