  The

  of 
  this 
  form 
  in 
  the 
  British

  is 
  stated

   have 
  come

  but 
  no 
  particulars 
  are 
  given. 
  It 
  seems 
  in 
  

   its 
  jet 
  black 
  legs 
  and 
  under 
  parts 
  to 
  be 
  more 
  nearly 
  allied 
  to 
  L. 
  bou- 
  

   tourlini 
  than 
  to 
  L. 
  stuhlmanni 
  and 
  differs 
  from 
  it 
  in 
  having 
  the 
  

   cheeks 
  and 
  sides 
  of 
  the 
  neck 
  jet
