Molluscs of Wisconsin age are described from nine localities bordering the Ohio River in western Kentucky. The area is covered by the Henderson, Smith Mills, and Wilson 7 1/2-minute quadrangles. The faunas, with a single exception, are from the Peoria loess. Molluscs were recovered from the Farmdale loess at one locality. Thirty-two species representing 12 families are covered by the study. Twenty-eight of these species are land gastropods. Of the remaining four, three are semiaquatic and one true aquatic. The general paleoenvironment is considered to have been a moist situation inhabited by species living in marsh and flood plain regions close to bodies of water. The area was forested or forest bordered and the climate was cool.

Recent studies of Paleocene strata from Reidland, Kentucky, have revealed significant foraminiferal assemblage in the Clayton(?) formation. The fauna is interesting, first because of its occurrence in a 6-inch zone occupying the extreme top of the Clayton (?) formation and, secondly, because the fauna contains certain species, such as Textularia plummerae, Bulimina quadrata, Pseudoparrella exigua, Alabamina wilcoxensis, Asterigerina primaria, and others, that characterize the upper part of the Midway in Texas and Alabama. In this regard, Newton and others (1961, p. 64-66) reported Bulimina quadrata and Alabamina wilcoxensis as occurring in possible Clayton as well as in a transitional zone between the Clayton and Porters Creek formations and in the lower 50 feet of the Porters Creek in Alabama. In Kentucky these species may have transgressed time lines and now characterize the Clayton (?) formation rather than the upper part of the Paleocene as in the southern parts of the Mississippi Embayment area. Thus the Clayton (?) formation in Kentucky may have been deposited in a transgressive sea. On this basis, the Clayton(?) would be progressively geologically younger northward and constitute the stratigraphic equivalent of the Clayton in the southern part of the Embayment. Other interesting facts about his foraminiferal fauna are the chemical composition of the tests and richness in numbers of individuals and diversity of species. The species belong to the so-called "smaller" Foraminifera. All tests, even those of normally calcareous species, are noncalcareous; none react to dilute hydrochloric acid. The assemblage includes 17 families, 36 genera, and 63 species.
