  in 
  bad

  almost 
  

   bleached,

  it

  very 
  faint 
  colour-bands.

  Differs 
  from 
  the 
  typical 
  A. 
  ovata 
  in 
  its 
  broader, 
  rather 
  oblique 
  

   form, 
  and 
  its 
  more 
  or 
  less 
  roughly 
  plicate 
  surface. 
  Specimens 
  in 
  

   Bourguignat's 
  collection 
  representing 
  ovata 
  and 
  Kordofana 
  present 
  

   such 
  differences 
  that 
  it 
  is 
  no 
  wonder 
  they 
  have 
  been 
  regarded 
  as 
  

   distinct 
  species, 
  but 
  intermediate 
  forms 
  show 
  the 
  connexion.
