  oblique 
  groups 
  

   behind 
  the

  Head 
  nearly 
  as 
  long 
  as 
  broad, 
  sometimes 
  slightly 
  

   broader 
  than 
  long, 
  sometimes 
  slightly 
  longer 
  than 
  

   broad, 
  more 
  depressed 
  than

  less

  The

  much 
  in 
  shape: 
  it 
  may 
  be 
  short 
  and 
  rounded,
