  Notes 
  on 
  the 
  Radiolaria 
  of 
  the 
  London 
  Clay."

  Microscopical 
  examination 
  of 
  the 
  London 
  Clay 
  of 
  Sheppey 
  and 
  

   elsewhere 
  has 
  afforded 
  proof 
  of 
  the 
  existence 
  of 
  a 
  Diatomaceous 
  

   zone 
  near 
  the 
  base 
  of 
  the 
  formation. 
  The 
  formation 
  of 
  a 
  well 
  for 
  the 
  

   Queenborough 
  Cement 
  Company 
  in 
  1885 
  was 
  the 
  means 
  of 
  furnish- 
  

   ing 
  a 
  laminated 
  clay 
  with 
  glittering 
  patches 
  of 
  Diatoms 
  from 
  a 
  depth 
  

   of 
  225 
  feet. 
  In 
  this 
  were 
  also 
  found 
  fairly 
  good 
  pyritized 
  specimens 
  

   of 
  Radiolaria, 
  some 
  of 
  which 
  were 
  submitted 
  to 
  Prof. 
  Ernst 
  Hackel, 
  

   who 
  found 
  a 
  large 
  number 
  of 
  fragments 
  of 
  Tertiary 
  Radiolaria, 
  but 
  

   few 
  well-preserved 
  specimens 
  appertaining 
  to 
  the 
  families 
  Splne- 
  

   roidea, 
  Discoidea, 
  and 
  Cyrtoidea, 
  and 
  apparently 
  identical 
  with 
  

   those 
  described 
  from 
  the 
  Tertiary 
  Tripoli 
  beds 
  of 
  Grotte. 
  No 
  new 
  

   species 
  occurred 
  among 
  the 
  recognized 
  forms. 
  

  

  Sketches 
  made 
  by 
  Mr. 
  A. 
  L. 
  Hammond 
  were 
  also 
  submitted 
  to 
  

   Prof. 
  Hackel, 
  who 
  stated 
  that 
  these 
  forms 
  were 
  not 
  identical 
  with 
  

   any 
  known 
  species, 
  recent 
  or 
  fossil. 
  

  

  The 
  Author 
  described 
  the 
  following 
  new 
  species 
  -.—ConiuteTlct 
  

   Hammondi, 
  Spongodiscus 
  asper, 
  and 
  Monosphoera 
  toliapica. 
  

  

  The 
  specimens 
  were 
  preserved 
  in 
  iron-pyrites. 
  

  

  Some 
  Tetractinellid 
  sponge-spicules 
  from 
  the 
  washings 
  were 
  

   recognized 
  by 
  Professor 
  Sol] 
  as.

  Description 
  of 
  a 
  new 
  Species 
  of 
  Glupea 
  (C. 
  vectensis) 
  from 
  

   Oligocene 
  Strata 
  in 
  the 
  Isle 
  of 
  Wight." 
  By 
  E. 
  T. 
  Newton, 
  Esq., 
  

   F.G.S. 
  

  

  A 
  number 
  of 
  small 
  fishes 
  found 
  by 
  Mr. 
  G. 
  W. 
  Colenutt, 
  of 
  Ryde, 
  

   during 
  his 
  investigations 
  of 
  the 
  Oligocene 
  strata 
  of 
  the 
  Isle 
  of 
  Wight, 
  

   in 
  beds 
  belonging 
  to 
  the 
  " 
  Osborne 
  Series," 
  were 
  described 
  as 
  belonging 
  

   to 
  a 
  new 
  species 
  of 
  Olupea. 
  The 
  specimens 
  vary 
  in 
  length 
  from 
  20 
  

   to 
  nearly 
  60 
  millim. 
  In 
  all 
  of 
  them 
  the 
  head 
  is 
  much 
  broken 
  ; 
  but 
  

   the 
  rest 
  of 
  the 
  body 
  is 
  beautifully 
  preserved, 
  showing 
  most 
  distinctly 
  

   the 
  vertebral 
  column, 
  ribs, 
  fins, 
  tail, 
  and 
  ventral 
  spines. 
  The 
  single 
  

   dorsal 
  fin 
  has 
  its 
  front 
  rays 
  about 
  midway 
  between 
  the 
  tip 
  of 
  the 
  

   snout 
  and 
  the 
  base 
  of 
  the 
  tail, 
  the 
  ventral 
  fins 
  being 
  immediately 
  

   under 
  the 
  front 
  of 
  the 
  dorsal 
  and 
  about 
  midway 
  between 
  the 
  pec- 
  

   toral 
  and 
  anal 
  fins. 
  The 
  anal 
  fin 
  commences 
  about 
  halfway 
  between 
  

   the 
  ventral 
  fins 
  and 
  the 
  base 
  of 
  the 
  tail, 
  occupying 
  about 
  two 
  thirds 
  

   of 
  that 
  distance, 
  and 
  the 
  tail 
  is 
  deeply 
  forked. 
  The 
  scales 
  are 
  thin 
  

   and 
  in 
  most 
  cases 
  much 
  broken 
  ; 
  while 
  the 
  ventral 
  region 
  of 
  the 
  

   body 
  is 
  armed 
  with 
  a 
  row 
  of 
  strong 
  spines. 
  The 
  spinal 
  column 
  

   contains 
  about 
  40 
  vertebrae, 
  of 
  which 
  14 
  or 
  15 
  are 
  caudal. 
  The 
  

   bones 
  of 
  the 
  head 
  are 
  mostly 
  broken, 
  but 
  those 
  of 
  which 
  the 
  outline 
  

   can 
  be 
  traced 
  agree 
  with 
  the 
  corresponding 
  parts 
  of 
  the 
  Sprat. 
  

  

  These 
  fishes 
  are 
  referred 
  to 
  the 
  genus 
  Chipea 
  ; 
  but 
  although 
  very 
  

   closely 
  allied 
  to 
  the 
  Common 
  Herring 
  and 
  Sprat, 
  the 
  relative 
  positions 
  

   of 
  the 
  dorsal 
  and 
  ventral 
  fins, 
  as 
  well 
  as 
  the 
  number 
  of 
  vertebra?, 
  

   prevent 
  their 
  being 
  placed 
  in 
  any 
  known 
  species 
  either 
  recent 
  or 
  

   fossil, 
  and 
  they 
  are 
  therefore 
  regarded 
  as 
  a 
  new 
  form 
  and 
  named 
  

   ' 
  'lupea 
  vectensis.
