Jones at the Bennett quarries, The Natural History Society Have a fine collection of Pittsford eurypterids from Pittsford and Fairport, N.Y. Teller Collection is here and on exhibition. Minus the large Bennett Collection of eurypt- eridids. What has become of it? In the Bennett quarries paid most attention to the Chemung-Ormdaga contact. As a rule it is an undulating contact ranging between six inches but in places it is as much as eighteen inches. In most places there is an intercourse, carbonaceous, slightly sandy shale with scattered pieces of the Chemung and some iron pyrite. The Ormdaga limestone begins above with an abundance of fossils, mainly brachiopods and a fewif bivalve limestone. In places the basal Ormdaga may be sandy or conglomeratic, but as a rule there is none of the latter. Saw no fossil jowts in the Chemung.
