This faunule displays very clearly the characteristics of the Ithaca 
fauna. All of the brachiopods occur in the Ithaca fauna, and most of 
the other species are known in it. The presence of Productella 
hallana, a rare species in eastern faunas, is noteworthy. 
Zone 17 of Hollowing Run section (1^5 1^ A). — One hundred and 
twenty -five feet of sandy beds, containing very few fossils, succeed 
the last zone. 
Zone 18 of Hollowing Ran section (ll^lf A). — At the top of zone 17 
are 4 inches of closely crowded shells, which contain the following 
species:
