had sent Quaternary fossils and collected Pupilla muscorum, which were abundant in one stratum, Vallonia gracillicosta, Succinea grosvenori and 2 specimens of Lymnaea sp. The latter had not been seen by me before. We did not find Planorbis parvus, which Cannon had found there. In a lateral gulch, in West bluffs of the Platte, NE of Cheltenham schoolhouse, we found one larger specimen of Succinea grosvenori in deposits of aeolian origin probably, as the opposite bluff of the gulch is undoubtedly aeolian. Well up the hill N of the latter point a street cut exposed acqueous deposits dipping SE perhaps 6 or 8 degrees or more, and quite regular in stratification. Does this indicate folding in recent times.
