  A 
  form 
  which 
  has 
  so 
  far 
  been 
  of 
  rare 
  occurrence 
  possesses 
  

   characters 
  which 
  compel 
  the 
  formation 
  of 
  a 
  new 
  genus. 
  This 
  

   form 
  has 
  hitherto 
  been 
  placed 
  with 
  a 
  query 
  in 
  the 
  genus 
  

   Unitrypa 
  and 
  is 
  represented 
  by 
  the 
  species 
  Unitrypa 
  consimilis. 
  

  

  As 
  in 
  the 
  genus 
  Unitrypa 
  the 
  carinae 
  are 
  continuous 
  plates, 
  

   with 
  expanded 
  summits, 
  connected 
  by 
  lateral 
  processes; 
  these 
  

   processes 
  are 
  not 
  oblique 
  plates 
  characteristic 
  of 
  Unitrypa, 
  but 
  

   strong 
  bars 
  resembling 
  the 
  dissepiments 
  of 
  the 
  frond, 
  the 
  carinae 
  

   are 
  very 
  much 
  expanded 
  above, 
  about 
  equal 
  in 
  thickness 
  to 
  the 
  

   branches 
  of 
  the 
  frond, 
  their 
  summits 
  and 
  also 
  the 
  connecting 
  

   bars 
  are 
  carinated, 
  the 
  whole 
  structure 
  resembling 
  the 
  non- 
  

   celluliferous 
  face 
  of 
  a 
  Fenestella. 
  The 
  connecting 
  bars 
  are 
  about 
  

   equal 
  in 
  number 
  to 
  the 
  dissepiments, 
  but 
  do 
  not 
  correspond 
  to 
  

   them 
  in 
  position. 
  

  

  The 
  genus 
  differs 
  from 
  Isotrypa 
  in 
  the 
  fact 
  that 
  the 
  carina 
  is 
  a 
  

   continuous 
  plate 
  of 
  equal 
  strength. 
  The 
  summits 
  of 
  the 
  carinae 
  

   and 
  connecting 
  bars 
  are 
  much 
  stronger 
  than 
  in 
  that 
  genus, 
  and 
  

   much 
  more 
  closely 
  resemble 
  the 
  non-celluliferous 
  face 
  of 
  the 
  

   frond. 
  It 
  also 
  differs 
  in 
  the 
  absence 
  of 
  the 
  large 
  pores 
  on 
  the 
  

   non-celluliferous 
  face 
  of 
  the 
  frond. 
  It 
  can 
  not 
  be 
  placed 
  in 
  the 
  

   genus 
  Tectulipora, 
  which 
  it 
  most 
  closely 
  resembles, 
  for 
  in 
  that 
  

   the 
  dissepiments 
  are 
  carinated 
  in 
  the 
  same 
  manner 
  as 
  the 
  

   branches 
  ; 
  of 
  equal 
  strength 
  with 
  the 
  carinae 
  of 
  the 
  branches 
  and 
  

   coalescing 
  with 
  them, 
  in 
  this 
  respect 
  corresponding 
  with 
  the 
  genus 
  

   Loculipora. 
  As 
  it 
  most 
  closely 
  resembles 
  the 
  genus 
  Tectulipora 
  

   I 
  propose 
  for 
  this 
  group 
  the 
  name 
  Tectuliporella. 
  

  

  TECTULIPORA, 
  Hall.

  Through 
  some 
  unaccountable 
  error 
  

   in 
  the 
  description 
  of 
  the 
  plate 
  the 
  species 
  figured 
  is 
  designated 
  

   Fenestella 
  parallela. 
  It 
  is 
  needless 
  to 
  say 
  it 
  has 
  no 
  resemblance 
  

   to 
  that 
  species.)
