NOTES ON THE PALAEONTOLOGY OF CERTAIN CHESTER 
FORMATIONS IN SOUTHERN INDIANA. 
ALLEN D. Hoe, Earlham College. 
In the course of an examination of the Chester formations of southern 
Indiana in the summer of 1918, especial care was taken at a few points 
to secure a representative collection of the fossils present. The study 
of the collections made at that time has not yet been completed, but 
enough has been done to make clear certain interesting relations between 
the formations exposed in Indiana and those which have been examined 
in southern and southwestern Illinois, and for this reason it has seemed 
worth while to record the results apparent in the work thus far. 
The localities from which the largest number of species were col- 
lected are all in Orange County, and the horizons yielding the greatest 
abundance of well-preserved specimens were of limestone, three in 
number. 
RENAULT LIMESTONE. 
The lowest of the three limestones referred to yielded the following 
forms: 
Talarocrinus, somewhat abundant, one or two species. 
Pentremites, somewhat abundant, including some very small forms. 
Cup coral (Zaphrentis?). 
Bryozoans (Archimedes rarely present). 
Cliothyridina sublamellosa (Hall). 
Composita sulcata, Weller. 
Composita trinuclea (Hall). 
Diaphragmus elegans (Norwood and Pratten). 
Eumetria vera (Hall). 
Girtyella (cf.) indianensis (Girty). 
Orthothetes kaskaskiensis (McChesney). 
Productus ovatus, Hall. 
Productus parvus, Meek and Worthen. 
Spirifer, sp. (near breckenridgensis, Weller). 
The above fauna, considered in connection with the relation of this 
limestone to the other formations exposed, seems to afford sufficient evi- 
dence to justify the correlation of this horizon with the Renault of 
Illinois as defined by Weller.
