  Museum. 
  

  

  antly 
  ; 
  branches 
  somewhat 
  slender, 
  from 
  eight 
  to 
  ten 
  in 
  the 
  

   space 
  of 
  five 
  millimetres 
  ; 
  bifurcations 
  frequent 
  and 
  irregular. 
  

   On 
  the 
  non-poriferous 
  side, 
  branches 
  rounded, 
  marked 
  with 
  

   line, 
  but 
  distinct 
  striae, 
  of 
  which 
  there 
  are 
  from 
  five 
  to 
  seven 
  on 
  

   the 
  width 
  of 
  the 
  branch. 
  Dissepiments 
  slender, 
  about 
  one- 
  

   third 
  as 
  wide 
  as 
  the 
  branches, 
  and 
  expanding 
  at 
  their 
  junction, 
  

   rounded 
  on 
  the 
  non-poriferous 
  side 
  and 
  sharply 
  angular 
  or 
  

   carinate 
  on 
  the 
  poriferous 
  side 
  ; 
  five 
  to 
  seven 
  in 
  the 
  space 
  of 
  

   five 
  millimetres. 
  Fenestrates 
  subquadrangular 
  or 
  broadly 
  

   oval, 
  width 
  varying 
  from 
  one-half 
  to 
  twice 
  the 
  width 
  of 
  the 
  

   branches, 
  length 
  once 
  and 
  a 
  half 
  to 
  twice 
  the 
  width. 
  Cell- 
  

   apertures 
  in 
  two 
  ranges; 
  generally 
  four 
  and 
  sometimes 
  five 
  in 
  

   the 
  space 
  of 
  each 
  fenestrate, 
  circular 
  or 
  slightly 
  oval, 
  opening 
  

   nearly 
  directly 
  upward 
  ; 
  distance 
  from 
  each 
  other 
  less 
  than 
  

   the 
  diameter 
  of 
  the 
  aperture 
  ; 
  margins 
  distinctly 
  elevated 
  and 
  

   slightly 
  indenting 
  the 
  border 
  of 
  the 
  fenestrate 
  ; 
  space 
  between 
  

   the 
  ranges 
  of 
  cellules 
  carinated 
  ; 
  carina 
  sharp, 
  elevated 
  and 
  

   nodose, 
  the 
  nodes 
  in 
  well-preserved 
  specimens 
  prominent, 
  

   about 
  fifteen 
  in 
  the 
  space 
  of 
  five 
  millimetres. 
  

  

  A 
  characteristic 
  of 
  this 
  species 
  is 
  the 
  nodose 
  carina, 
  a 
  fea- 
  

   ture 
  not 
  observed 
  in 
  any 
  other 
  species 
  from 
  this 
  locality.

  Bryozoum 
  funnel-form, 
  narrowly 
  expanding 
  below 
  and 
  

   spreading 
  above, 
  sides 
  undulated. 
  Branches 
  rigid, 
  eleven 
  or 
  

   twelve 
  in 
  the 
  space 
  of 
  five 
  millimetres 
  ; 
  non-poriferous 
  sides 
  

   slightly 
  rounded, 
  longitudinally 
  striated 
  ; 
  striae 
  very 
  strong 
  

   and 
  prominent, 
  three 
  or 
  four 
  in 
  the 
  width 
  of 
  the 
  branch. 
  Dis- 
  

   sepiments 
  about 
  half 
  the 
  width 
  of 
  the 
  branches 
  as 
  they 
  appear 
  

   on 
  the 
  non-poriferous 
  side, 
  about 
  seven 
  or 
  eight 
  in 
  the 
  space 
  of 
  

   five 
  millimetres, 
  expanding 
  at 
  their 
  junction 
  with 
  the 
  branches 
  

   and 
  transversely 
  striated 
  ; 
  on 
  the 
  poriferous 
  side 
  depressed 
  

   and 
  angular. 
  Fenestrates 
  broadly 
  oval, 
  a 
  little 
  wider 
  than 
  

   the 
  branch, 
  length 
  from 
  one 
  and 
  one-third 
  to 
  twice 
  the 
  width, 
  

   appearing 
  narrower 
  and 
  sometimes 
  nearly 
  obsolete 
  on 
  the
