  Gen. 
  Char. 
  — 
  Depressed 
  ; 
  the 
  head 
  broad, 
  without 
  eyes 
  or 
  facial 
  

   suture. 
  A 
  broad 
  slightly 
  clavate 
  glabella, 
  with 
  three 
  complete 
  trans- 
  

   verse 
  lobes 
  and 
  one 
  incomplete 
  lobe 
  on 
  either 
  side. 
  The 
  cheeks 
  obtusely 
  

   triangular, 
  rugose, 
  strongly 
  margined. 
  Body 
  of 
  many 
  segments, 
  cer- 
  

   tainly 
  more 
  than 
  eleven, 
  with 
  obtuse 
  pleurae 
  square 
  at 
  the 
  ends, 
  and 
  

   with 
  the 
  fulcrum 
  close 
  to 
  the 
  axis. 
  Tail 
  transverse, 
  of 
  few 
  segments, 
  

   with 
  a 
  broad 
  serrate 
  limb, 
  and 
  a 
  wide 
  axis 
  of 
  three 
  or 
  four 
  rings. 
  

  

  Under 
  this 
  name 
  I 
  have 
  to 
  introduce 
  to 
  notice 
  a 
  singular 
  Trilobite, 
  

   which 
  resembles 
  the 
  Atops 
  of 
  Emmons's 
  figures 
  *, 
  an 
  elongated 
  ex- 
  

   panded 
  glabella 
  overhanging 
  the 
  front 
  ; 
  and 
  it 
  has 
  no 
  transverse 
  fur- 
  

   rows 
  completely 
  across. 
  It 
  is 
  nearer, 
  in 
  all 
  probability, 
  to 
  Sao 
  and 
  

   Conocephalus, 
  while 
  Anopolenus, 
  however 
  abnormal, 
  is 
  one 
  of 
  the 
  

   close 
  allies 
  of 
  Paradoxides.

  We 
  have 
  only 
  a 
  few 
  specimens, 
  but 
  the 
  form 
  is 
  too 
  peculiar 
  to 
  admit 
  

   of 
  a 
  doubt 
  as 
  to 
  its 
  being 
  a 
  new 
  and 
  very 
  distinct 
  genus. 
  It 
  was 
  

   found, 
  with 
  nearly 
  the 
  whole 
  of 
  the 
  specimens 
  described 
  in 
  this 
  paper, 
  

   by 
  Mr. 
  Henry 
  Hicks, 
  and 
  I 
  wish 
  to 
  record 
  his 
  services 
  to 
  palaeon- 
  

   tology 
  in 
  working 
  out 
  this 
  fauna. 
  

  

  A 
  species 
  of 
  Conocoryphe 
  is 
  also 
  a 
  new 
  form, 
  and 
  may 
  very 
  possibly 
  

   belong 
  to 
  a 
  new 
  genus.

  We 
  have 
  only 
  the 
  head 
  and 
  body-rings 
  of 
  this 
  curious 
  species, 
  which 
  

   eould 
  not 
  have 
  been 
  much 
  more 
  than 
  an 
  inch 
  long. 
  The 
  head 
  is 
  

   wider 
  than 
  the 
  body, 
  semicircular, 
  and 
  with 
  the 
  glabella 
  deeply 
  

   divided 
  from 
  the 
  cheeks 
  and, 
  as 
  it 
  were, 
  sunk 
  in 
  them. 
  

  

  The 
  glabella 
  is 
  parabolic 
  and 
  convex 
  ; 
  two 
  obscure 
  lateral 
  furrows 
  

   indent 
  the 
  sides, 
  but 
  very 
  slightly. 
  The 
  cheeks 
  are 
  broad, 
  nearly 
  

   as 
  convex 
  as 
  the 
  glabella, 
  and 
  bear 
  a 
  very 
  small 
  eye, 
  rather 
  remote 
  

   from 
  the 
  glabella, 
  about 
  half 
  its 
  full 
  diameter 
  apart 
  from 
  it. 
  The 
  

   facial 
  suture 
  curves 
  out 
  above 
  the 
  eye, 
  and 
  beneath 
  it 
  again 
  out- 
  

   wards 
  to 
  near 
  the 
  very 
  shortly 
  spinous 
  angle. 
  The 
  head 
  is 
  margi- 
  

   nate 
  all 
  round. 
  A 
  strong 
  coarse 
  tuberculation 
  covers 
  the 
  surface 
  of 
  

   the 
  glabella 
  and 
  the 
  cheeks. 
  The 
  tubercles 
  are 
  so 
  prominent 
  and 
  

   sharp 
  as 
  to 
  be 
  more 
  like 
  spines. 
  

  

  Nine 
  body-rings 
  are 
  all 
  that 
  are 
  preserved. 
  They 
  have 
  a 
  narrow 
  

   axis, 
  and 
  deeply 
  sulcate 
  pleurae 
  bent 
  down 
  strongly 
  at 
  a 
  point 
  beyond 
  

   the 
  fulcrum. 
  The 
  front 
  half 
  of 
  the 
  pleura 
  is 
  the 
  more 
  convex, 
  and 
  

   has 
  three 
  or 
  four 
  strong 
  conspicuous 
  tubercles 
  on 
  it. 
  In 
  this 
  respect 
  

   and 
  in 
  the 
  general 
  form 
  and 
  ornament 
  of 
  the 
  head 
  there 
  is 
  much 
  

   resemblance 
  to 
  C. 
  Ribeiro, 
  Barr., 
  a 
  species 
  found 
  in 
  the 
  Primordial 
  

   schists 
  of 
  Spain 
  f. 
  That 
  species 
  has, 
  however, 
  an 
  ocular 
  ridge 
  and 
  

   larger 
  eyes 
  ; 
  but 
  the 
  two 
  forms 
  are 
  very 
  closely 
  related. 
  If 
  it 
  were 
  

   not 
  for 
  the 
  existence 
  of 
  this 
  Spanish 
  species, 
  I 
  should 
  have 
  more
