  connected 
  with 
  the 
  typical 
  V. 
  pygmaea 
  (figs. 
  53-56) 
  through 
  Sagrina 
  

   pulchella, 
  D'Orb., 
  but 
  an 
  intermediate 
  condition 
  between 
  it 
  and 
  the 
  

   feebler 
  dimorphs 
  of 
  the 
  Mediterranean 
  area 
  occurs 
  in 
  the 
  mud 
  

   brought 
  up 
  by 
  the 
  sounding 
  lead 
  from 
  the 
  Abrohlos 
  Bank 
  ( 
  U. 
  di- 
  

   morpha)." 
  "Altogether 
  this 
  latter 
  group 
  of 
  forms 
  shows 
  how 
  great 
  

   the 
  affinity 
  is 
  between 
  the 
  always 
  hyaline 
  Uvigerina 
  and 
  the 
  porous 
  

   sandy 
  Textularia." 
  

  

  Brady 
  in 
  the 
  Challenger 
  Report 
  notes 
  the 
  relationships 
  of 
  both 
  Sa- 
  

   grina 
  pulchella 
  and 
  S. 
  rugosa 
  to 
  the 
  Textulariidae. 
  

  

  A 
  study 
  of 
  collections 
  from 
  the 
  West 
  Indies 
  and 
  the 
  coast 
  of 
  Florida 
  

   has 
  shown 
  conclusively 
  that 
  the 
  Sagrina 
  pulchella 
  of 
  d'Orbigny 
  is 
  in 
  

   reality 
  a 
  Bolivina 
  which 
  is 
  widely 
  distributed 
  in 
  that 
  general 
  region. 
  

   The 
  peculiar 
  apertural 
  characters 
  with 
  the 
  sides 
  somewhat 
  raised 
  

   could 
  have 
  easily 
  been 
  mistaken 
  for 
  the 
  sort 
  of 
  aperture 
  in 
  d'Orbigny's 
  

   figure, 
  if 
  the 
  specimen 
  were 
  not 
  seen 
  from 
  the 
  end. 
  With 
  S. 
  pulchella 
  

   really 
  a 
  species 
  of 
  Bolivina, 
  and 
  as 
  Brady 
  notes 
  S. 
  rugosa 
  is 
  related 
  to 
  

   Gaudryina 
  it 
  follows 
  that 
  Sagrina, 
  if 
  used 
  at 
  all, 
  must 
  be 
  used 
  for 
  

   species 
  belonging 
  to 
  the 
  Textulariidae. 
  As 
  the 
  type 
  species 
  is 
  a 
  

   Bolivina 
  the 
  name 
  Sagrina 
  can 
  not 
  be 
  used 
  unless 
  for 
  a 
  part 
  of 
  that 
  

   genus. 
  

  

  The 
  first 
  name 
  that 
  can 
  be 
  taken 
  up 
  for 
  the 
  generic 
  characters 
  of 
  

   the 
  species 
  noted 
  by 
  Parker 
  and 
  Jones 
  is 
  Siphogenerina 
  Schlumber- 
  

   ger. 
  Schlumberger 
  called 
  attention 
  to 
  the 
  internal 
  structure, 
  and 
  

   erected 
  the 
  genus 
  Siphogenerina 
  based 
  on 
  the 
  tubular 
  connecting 
  in- 
  

   terior. 
  4 
  The 
  genus 
  is 
  related 
  to 
  Uvigerina 
  and 
  Trifarina 
  (Triplasia 
  

   or 
  Rhabdogonium) 
  and 
  to 
  the 
  group 
  of 
  the 
  Lagenidae 
  with 
  apertures 
  

   exserted, 
  with 
  a 
  tubular 
  neck 
  and 
  phialine 
  lip.
