  in 
  front, 
  the 
  nearly 
  flat, 
  verti- 
  

   cal 
  face 
  extendmg 
  upward 
  to 
  form 
  a 
  broad 
  truncate 
  horn 
  about 
  one- 
  

   fourth

  The 
  face 
  and 
  sides 
  of 
  the 
  horn 
  reticulate, 
  

   the

   from 
  the 
  flattened 
  discal 
  surface 
  of 
  the
