  some

  were 
  collected

  small 
  butte, 
  about 
  100

  The

   fossils 
  is 
  on 
  the

  This 
  locality 
  offers 
  a 
  more 
  complete 
  Middle 
  Oligocene 
  

   section 
  than 
  the 
  preceding 
  one. 
  About 
  140 
  feet 
  of 
  sediments 
  are 
  

   exposed 
  at 
  this 
  locality. 
  At 
  the 
  base 
  they 
  are 
  hght 
  gray 
  to 
  buff 
  

   clayey 
  ash, 
  grading 
  to 
  nearly 
  pm-e 
  ash, 
  grayish 
  green, 
  at 
  the 
  top. 
  The 
  

   same 
  f 
  aunal 
  assemblage 
  is 
  found 
  in 
  the 
  lower 
  levels 
  as 
  at 
  the 
  preceding 
  

   locaUty 
  but 
  no 
  identifiable 
  specimens 
  were 
  obtained 
  from 
  the 
  upper 
  

   levels.
