  Aperture

   area 
  broad, 
  round 
  or 
  somewhat 
  elongate, 
  frequently 
  with 
  the 
  proximal 
  

   edge 
  nearly 
  straight, 
  margin 
  broad, 
  raised, 
  sloping 
  inwards. 
  Ovicell 
  

   small, 
  globose, 
  narrow. 
  The 
  aperture 
  is 
  about 
  0*22 
  millim. 
  wide 
  and 
  

   of 
  about 
  the 
  same

  this 
  species, 
  viz. 
  M. 
  catenularia, 
  Lacroiocii, 
  

   pilosa,

  monostachys, 
  no 
  ovi

   Membranipor

  a

  This 
  figure 
  is 
  not 
  successful, 
  as 
  the 
  walls 
  of 
  the 
  aperture 
  (which 
  slope 
  

   inwards) 
  are 
  not 
  very 
  well 
  shown.
