  AcHATiNA 
  Bandeieana, 
  Morelet. 
  

  

  Two 
  specimens 
  of 
  this 
  fine 
  species 
  were 
  secured 
  which 
  agree 
  well 
  

   with 
  Pfeiffer's 
  figure 
  in 
  the 
  Novitates 
  Concliologicm} 
  Morelet's 
  figure^ 
  

   seems 
  to 
  be 
  that 
  of 
  a 
  rather 
  young 
  shell 
  ; 
  having 
  had 
  an 
  opportunity 
  

   of 
  examining 
  the 
  series 
  of 
  this 
  species 
  in 
  the 
  British 
  Museum 
  I 
  think 
  

   there 
  can 
  be 
  little 
  doubt 
  that 
  A. 
  Bandeirana 
  and 
  A. 
  Dohrniana, 
  Pfr., 
  

   are 
  synonymous.

  Two 
  hundred 
  miles 
  due 
  east 
  of 
  Loanda, 
  Angola. 
  

  

  The 
  collection 
  included 
  a 
  fine 
  series 
  of 
  this 
  shell, 
  which 
  differs 
  

   from 
  Achatina 
  nigella, 
  Morel., 
  ^ 
  from 
  Pungo 
  Andongo, 
  Angola, 
  about 
  

   120 
  miles 
  to 
  the 
  south-east 
  of 
  the 
  locality 
  whence 
  the 
  present 
  species 
  

   was 
  obtained, 
  in 
  being 
  considerably 
  larger, 
  having 
  one 
  whorl 
  more, 
  

   and 
  in 
  the 
  sculpture 
  being 
  much 
  less 
  pronounced 
  ; 
  the 
  columella 
  also 
  

   is 
  not 
  nearly 
  so 
  arched, 
  and 
  is 
  not 
  abruptly 
  truncate 
  as 
  in 
  that 
  species.
