The predominating fossils of the Shepherd- denta bed are S. concava, S. dentata, Op. aceri- mirata and Atypus articulatus. These conditions seem to point to a way shallower sea during the time of the Shepher- denta - this for gone and a short land interval before the Hydraulic beds came in. That the sea was shallower previous to the Hydraulic is indicated by the granular nature of the limestone, the ground and frag- mentary corals, and the rounded pieces of foreign limestone. Further these beds are not laid down in even layers but are wavy and sometimes decidedly or in rolls of 2 feet or more. Along the edges of some of these rolls can be seen stylolites 2 to 3 1/2 inches high. The fossils have nothing to do with this structure. I saw them thus Stylolites Shepherdonta gone. These rolls can be seen to great advant- age between the east Jeffersonville line and the Smith and Dungan Mill foundation. One persistent roll follows the course of the
