﻿Erratum 
  for 
  the 
  June 
  number. 
  

  

  Attention 
  is 
  called 
  to 
  a 
  serious 
  error 
  in 
  the 
  June 
  number, 
  

   which 
  escaped 
  notice 
  in 
  reading 
  proofs. 
  

  

  On 
  page 
  475 
  in 
  the 
  title 
  of 
  the 
  3d 
  article, 
  Illinois 
  is 
  twice 
  mis- 
  

   used 
  in 
  place 
  of 
  Missouri. 
  It 
  should 
  read 
  Geological 
  Survey 
  of 
  

   Missouri, 
  vol. 
  iv, 
  Paleontology 
  of 
  Missouri, 
  etc. 
  Also 
  in 
  the 
  

   Index, 
  p. 
  487, 
  under 
  Geological 
  Reports 
  and 
  Surveys, 
  the 
  third 
  

   entry 
  should 
  be 
  Missouri, 
  not 
  Illinois 
  ; 
  and 
  on 
  p. 
  489, 
  the 
  first 
  

   line 
  should 
  read, 
  Keyes, 
  C. 
  R., 
  Paleontology 
  of 
  Missouri, 
  not 
  

   Illinois.
