  The 
  length 
  of 
  the 
  body 
  is 
  given 
  as 
  61 
  mm., 
  and 
  consequently 
  the 
  

   shell 
  would 
  be 
  almost 
  as 
  long. 
  

  

  The 
  only 
  other 
  South 
  African 
  species 
  which 
  has 
  the 
  spine 
  short 
  and 
  

   blunt 
  is 
  S. 
  papillata. 
  The 
  animal 
  of 
  that 
  species, 
  however, 
  does 
  not 
  

   agree 
  with 
  the 
  description 
  of 
  S.joussemimi, 
  since 
  no 
  mention 
  is 
  made 
  

   of 
  the 
  occurrence 
  of 
  closely 
  arranged 
  tubercles 
  so 
  characteristic 
  of 
  

   S. 
  pajyillata.

  At 
  the 
  above 
  reference 
  I 
  am 
  of 
  opinion 
  that 
  Dr. 
  Hoyle 
  has 
  included 
  

   two, 
  if 
  not 
  three, 
  distinct 
  species: 
  (1) 
  The 
  form 
  which 
  I 
  retain 
  as 
  

   burmipi 
  is 
  that 
  figured 
  on 
  pi. 
  i, 
  figs. 
  188, 
  189. 
  (2) 
  Figs. 
  190, 
  191 
  

   represent 
  a 
  second 
  species 
  or 
  possibly 
  the 
  female 
  of 
  the 
  above. 
  

   (3) 
  Fig. 
  192 
  is 
  a 
  third 
  species 
  having 
  several 
  distinguishing 
  features. 
  

  

  The 
  above 
  conclusions 
  have 
  been 
  arrived 
  at 
  through 
  the 
  study 
  of 
  

   a 
  further 
  series 
  of 
  specimens 
  sent 
  by 
  Mr. 
  Burnup, 
  These 
  I 
  submitted 
  

   to 
  Dr. 
  Hoyle, 
  and 
  he 
  writes 
  " 
  I 
  agree 
  with 
  you 
  that 
  there 
  are 
  three 
  

   forms", 
  but 
  he 
  detinitely 
  considers 
  No. 
  2 
  the 
  female 
  of 
  No. 
  1, 
  

   which 
  I 
  now 
  regard 
  as 
  tlie 
  type 
  of 
  burnupi. 
  He 
  may 
  be 
  right 
  in 
  his 
  

   conjecture, 
  but 
  until 
  the 
  animals 
  are 
  known 
  it 
  is 
  a 
  case 
  of 
  uncertainty, 
  

   and 
  therefore 
  I 
  have 
  suggested 
  a 
  distinctive 
  name 
  for 
  this 
  form 
  in 
  the 
  

   meantime.

  This 
  form 
  has 
  the 
  central 
  groove 
  in 
  the 
  ventral 
  surface 
  con- 
  

   spicuously 
  deep, 
  and 
  the 
  marginal 
  limbs 
  are 
  verj^ 
  prominent 
  and 
  

   closer 
  together. 
  Between 
  them 
  and 
  the 
  outer 
  chitinous 
  margin 
  the 
  

   surface 
  exhibits 
  very 
  peculiar 
  curved 
  indented 
  striae, 
  which 
  are 
  not 
  

   pi-esent 
  in 
  No. 
  2 
  (incerta). 
  The 
  spine 
  is 
  only 
  slightly 
  recurved. 
  The 
  

   dorsal 
  surface 
  exhibits 
  a 
  central 
  raised 
  tillet, 
  not 
  very 
  strongly 
  

   defined, 
  and 
  marked 
  with 
  transverse 
  wrinkles 
  or 
  lines 
  of 
  growth. 
  

   It 
  is 
  of 
  rosaceous 
  tint, 
  excepting 
  the 
  sides 
  anteriorly, 
  which 
  are 
  

   covered 
  with 
  yellowish 
  epidermis.

   The 
  central 
  groove 
  on 
  the 
  ventral 
  surface 
  is 
  not 
  so 
  deep 
  as 
  in 
  

   S. 
  burnupi 
  (No. 
  1), 
  and 
  the 
  marginal 
  limbs 
  are 
  wider 
  apart. 
  They 
  

   converge 
  to 
  a 
  sharp 
  point, 
  form 
  a 
  distinct 
  inner 
  cone, 
  and 
  are 
  united 
  

   to 
  the 
  chitinous 
  margin 
  of 
  the 
  outer 
  cone. 
  The 
  space 
  between 
  tlie 
  

   marginal 
  limbs 
  of 
  the 
  inner 
  cone 
  and 
  the 
  outer 
  chitinous 
  margin 
  is 
  

   quite 
  smooth, 
  and 
  not 
  striated 
  as 
  in 
  burnupi. 
  The 
  spine 
  is 
  more 
  

   distinctly 
  curved 
  towards 
  the 
  dorsal 
  surface 
  than 
  in 
  burnupi. 
  This 
  

   surface 
  has 
  a 
  conspicuous 
  rosy 
  central 
  stripe, 
  from 
  end 
  to 
  end, 
  much
