For practical pur- poses the groups of conodonts from the two units are indistinguishable. Conodonts from the Illinois and Indiana sections are nearly identical, both as to spe- cies present and the relative abundance of the species. Kladognathus is less common in Indiana; Spathognathodus campbelli was found in only one section, locality 2, in southwestern Illinois; Lonchodina cf. L. paraclarki was found only in the three In- diana sections. Otherwise the species coin- cide. Southern Faunal Province In the south part of the area studied there is a noticeable change in the fauna, as shown by comparing species collected at localities 7 and 8 in Christian and Butler counties, Kentucky, with those from the LOG.
