148 Talbot — Fauna of the IStafford Limestone of New York. 



Art. XTY. — A Contribution to a List of the Fauna of the 

 Stafford Limestone of New York ; by Mignon Talbot. 



The Stafford limestone, as stated by Dr. J. M. Clarke,^ is 

 the western of the two comparatively persistent limestones of 

 the Marcellus shale of I^ew York, and extends from a point 

 near Phelps, Ontario County, to Lake Erie. Several outcrops 

 have been recorded and studied. These may be found along 

 Flint Creek and near Baggerly Corners in Ontario County ; at 

 Littleville and at another spot near Avon, in Livingston County ; 

 at Stafford, Leroy, and Batavia, in Genesee County ; and at 

 Wende, at Lancaster, and near Buffalo,t in Erie County. 

 Borings from various salt shafts show its presence at York, 

 Livonia, and the outlet of Conesus Lake, in Livingston County, 

 and Miss Elvira Wood:}: reports it from a sewer excavation in 

 Buffalo. 



Three small collections of this limestone, one from Batavia 

 and two from Leroy, ]N". Y., have been worked out in the pale- 

 on tological laboratory of the Yale University Museum, and 

 a number of species not previously reported from this horizon 

 has been found, sufficient to warrant the publication of a list 

 supplemental to those given by Dr. Clarke and Miss Wood. 



Li Miss Wood's account of the section at Lancaster, the low- 

 est bed of the limestone is described as made up largely of 

 Strophalosia truncata and Ambocodia nana. This same rock, 

 together with typical Stafford material, is in the collection 

 from Batavia, about forty miles to the east of Lancaster. 

 AVithout visiting the section, it would be unwise to attempt to 

 interpret the occurrence of this bed at Batavia, as, unfortunately, 

 its exact horizon was not reported. Of the two collections from 

 Leroy, only ten miles farther east, neither contains this rock. 



In studying the Batavia and Leroy material in the Yale 

 University Museum, comparison with the lists as given from 

 the typical Stafford limestone and including the lower beds of 

 the Lancaster section resulted in the following : —
