South Benson trip. At Lunney, near Tracy, Prasophora simulatrix is abundant associated with Rhynchotrema macrourum abundant; Section immediately NW of Russell Mill = old site of Wrights Mill, 36 ft borealis scarce, at least, with Rhy. macrourum & Hebertella especially in lower 12 feet, 18 ft Prasophora simulatrix common Dalmanella macrourum occur in same layers as simulatrix and Rhynchotrema 22 to 35, at 35 Prasophora. 35 ft limestone with Dalmanella from Bed of creek = South Benson. The fine grained limestone ups the jolte less than a mile from Bridge point, out about 3 trough. Next section is taken immediately above the jolte— closing section. Rate Williams quarry, at the Devil's Hillar jolte, about 1 1/2 mi west of Frankfort, {Cross bedded limestone, 4 ft exposed probably Nicholas member, here only 7 1/2 Greenale member, lithologically and faunaally like this member, 5 ft massive limestone, assumed to be top of Paris bed. Does this prove that the Greenale member thins out westward? At the mouth of Devil's Hillar, lower site Frankfort, west of the river, Asterinus cylitic (2 specimens) were found.
