was completed the first season, and the results published in a report written 
by Dr. Galloway. It contains a discussion of the topography, descriptive, 
structural, and historical geology, and natural resources of the area, with 
an areal geological map and numerous diagrams. 
Collections of fossils from the separate divisions of the Stones River 
beds were made at every favorable locality during the first field season 
(1915) and during the second (1916) when the writer returned to com- 
plete the soil mapping. <A study of the material collected was made at 
Indiana University under the efficient and authoritative direction of Dr. 
BE. R. Cummings and aided by the useful suggestions of Dr. J. J. Galloway. 
The results of the paleontologic work forms the basis for this paper. The 
identifications and a portion of the descriptions were completed before mak- 
ing a visit to the U. S. National Museum to compare the new and old forms 
with the unpublished material of Dr. E. O. Ulrich and Dr. R. 8. Bassler. 
It was discovered that they had the following species described and photo- 
graphed : 
Ceramoporella grandis, new species. 
Ceramoporella ingenua, new species. 
Monticulipora compacta, new species. 
Monticulipora discula, new species. 
Monticulipora intersita, new species. 
In order to avoid complications of nomenclature by introducing new 
names for the used but unpublished ones the following given by Ulrich 
and Bassler were adopted: 
*Anolotichea exrplanata. 
*Mesotrypa crustulata. 
*Mesotrypa dubia. 
*Constellaria lamellosa. 
*Nicholsonella frondifera. 
*Hallopora spissata. 
*Batostoma suberassum. 
Batostoma dendroidea. 
Bastostoma conferia. 
Batostoma inutilis. 
*Stromatotrypa lamellata. 
*Rhinidictya tabulata. 
*Stictoporella cribrilina. 
Photographs of those above marked with an asterisk (*) were furnished 
by Dr. Bassler. The descriptions are the individual work of the writer 
and where the new forms were independently recognized from his collections 
a cotype was used. For the privilege to publish the descriptions of the new 
species prepared by Ulrich and Bassler, which increases the value of this 
paper as a paleontological contribution, expressions of gratitude are due to 
Dr. Ulrich and Dr. Bassler.
