  Discussion. 
  

  

  Mr. 
  Prestwich 
  thought 
  the 
  specimen 
  a 
  most 
  interesting 
  addition 
  

   to 
  the 
  derived 
  fossils 
  of 
  the 
  lower 
  beds 
  of 
  the 
  Red 
  Crag. 
  It 
  was 
  most 
  

   likely 
  derived 
  from 
  some 
  of 
  the 
  Miocene 
  beds 
  which 
  formerly 
  existed, 
  

   probably 
  on 
  what 
  is 
  now 
  the 
  basin 
  of 
  the 
  German 
  Ocean. 
  

  

  Mr. 
  H. 
  Woodward 
  mentioned 
  that 
  in 
  the 
  Woodwardian 
  Collection 
  

   there 
  was 
  a 
  skull 
  of 
  HoUiiherium 
  from 
  the 
  Miocene 
  of 
  Darmstadt. 
  It 
  

   was, 
  he 
  thought, 
  of 
  great 
  interest 
  to 
  meet 
  with 
  these 
  Miocene 
  forms 
  

   in 
  the 
  Crag, 
  most 
  of 
  the 
  fossils 
  of 
  which 
  appear 
  to 
  have 
  been 
  derived 
  

   from 
  the 
  lower 
  beds 
  of 
  the 
  London 
  Clay. 
  

  

  Dr. 
  Leith 
  Adams 
  mentioned 
  the 
  discovery 
  of 
  a 
  tooth 
  of 
  Halitlie- 
  

   rium 
  in 
  a 
  calcareous 
  bed 
  in 
  Malta, 
  where 
  also 
  he 
  had 
  discovered 
  one 
  

   of 
  the 
  ear-bones. 
  

  

  Mr. 
  Seelet 
  pointed 
  out 
  that 
  the 
  skull 
  presented 
  some 
  peculiari- 
  

   ties, 
  which 
  made 
  him 
  doubt 
  Whether 
  it 
  could 
  rightly 
  be 
  ascribed 
  to 
  

   Halitlierium. 
  He 
  thought 
  it 
  might 
  possibly 
  belong 
  to 
  a 
  new 
  genus 
  ; 
  

   at 
  the 
  same 
  time 
  he 
  had 
  noticed 
  in 
  the 
  Crag 
  deposits 
  some 
  vertebrae 
  

   which 
  he 
  thought 
  might 
  be 
  attributed 
  to 
  Halitlierium. 
  

  

  The 
  Chairman 
  (Prof. 
  Eamsay) 
  was 
  glad 
  to 
  find 
  that 
  so 
  many 
  

   geologists 
  were 
  disposed 
  to 
  regard 
  the 
  majority 
  of 
  the 
  fossil 
  bones 
  

   from 
  the 
  Crag 
  as 
  derivative. 
  He 
  bad 
  long 
  regarded 
  them 
  as 
  belonging 
  

   to 
  a 
  Miocene 
  period, 
  and 
  probably 
  a 
  late 
  one, 
  and 
  to 
  a 
  time 
  when 
  this 
  

   country 
  was 
  united 
  to 
  the 
  continent. 
  When 
  at 
  the 
  Crag 
  period 
  a 
  

   portion 
  of 
  the 
  surface 
  was 
  submerged, 
  the 
  neighbouring 
  land 
  might, 
  

   however, 
  have 
  been 
  still 
  inhabited 
  by 
  the 
  old 
  Miocene 
  fauna.
