Abstract
the Smithsonian Institution received from Mr. John H. Lemon of New Albany, Floyd 00., Maryland, a box of matelial collected by him at the Falls of the Ohio.The material consists of a piece of very porous and highly fossilif-erOllS chert about five inches square, and is accompanied by a small phial containing what the sender describes as "small shells which were picked from the dust of crushed Devonian chert."The so-called shells may be seen in small numbers scattered through the matrix, thus leaving no doubt as to the correctness of the assertion that they actually come from the same horizon.The formation from which the material comes is the Oomiferous limestone of the Lower Devonian.It is, of course, a marine deposit, and the material examined contains, besides the problematic organisms, numerous examples of two species of coral (Zaphrentis sp. and Oladopora sp.) and two Brachiopods (Sflreptorhynchus Ohemungensis val'.pandora Hall, and Spirij'era gTegaria Clapp), which have been identified for me by Mr. Ohas.D. Walcott of the U. S. Geological Survey.These problematic organisms were first sent to Mr. Walcott under the impression that they were foraminiferous shells, but as he failed to recognize any foraminiferal characters and regarding them as more probably of vegetable origin, he sent them to the Department of Fossil Plants.The organisms under consideration are minute, spirally grooved bodies from 1'50 to 1'80 mm.long and about 1'70 mm.
