  zons. 
  Mr. 
  J. 
  M. 
  Jessup 
  was 
  the 
  indefatigable 
  worker 
  through 
  

   whose 
  efforts 
  the 
  bulk 
  of 
  the 
  material 
  was 
  obtained. 
  Some 
  of 
  

   the 
  specimens 
  were 
  collected 
  by 
  Mr. 
  C. 
  L. 
  Breger 
  and 
  the 
  

   writer. 
  The 
  general 
  report* 
  on 
  this 
  trip, 
  which 
  has 
  already 
  

   been 
  issued, 
  contains 
  a 
  complete 
  section 
  of 
  the 
  Em 
  bar 
  forma- 
  

   tion. 
  It 
  is 
  the 
  writer's 
  expectation 
  soon 
  to 
  publish 
  in 
  a 
  bulletin 
  

   of 
  the 
  IT. 
  S. 
  Geological 
  Survey 
  a 
  more 
  detailed 
  description 
  of 
  

   the 
  stratigraphy 
  of 
  the 
  north 
  slope 
  of 
  the 
  Wind 
  River 
  Range. 
  

   This 
  will 
  include 
  the 
  Embar 
  formation.

  H. 
  Girty, 
  of 
  

   the 
  U. 
  S. 
  Geological 
  Survey, 
  to

   submitted, 
  reports 
  over 
  60 
  species 
  belonging 
  to 
  at 
  least 
  45 
  

   genera. 
  Although 
  most 
  of 
  the 
  fossils 
  are 
  brachiopods 
  and 
  

   pelecypods, 
  there 
  are 
  also 
  bryozoans, 
  crinoids, 
  scaphopods,
