JANUARY, 1902. MONROE HAMILTON FOSSILS FROM BETHANY, N. Y. 
57 
Notes on a Collection of Hamilton Fossils, from the Town of 
Bethany, Genesee Co«, N. 
By CHARLES E. MONROE. 
The writer's first acquaintance with Devonian fossils was made 
in connection with the hydrauUc limestone beds in the neighbor- 
hood of Milwaukee. These beds are rich in the remains both of 
fishes and invertebrates and are remarkable for the mingling of 
forms which are elsewhere widely separated geographically and 
vertically. The study of these forms and their proper determina- 
tion and correlation necessitated more extensive investigations and 
an acquaintance with the fossils of other localities. In the prog- 
ress of such investigations trips have been made into Iowa, Michi- 
gan and Ontario and interesting collections secured at Hackberry 
Grove, Petoskey and Thedford, all famous localities for fossils. 
Last May a visit was made to the town of Bethany, in Genesee 
County, N. Y., where for the first time the writer had an oppor- 
tunity to secure a large collection from the classical ground of the 
New York Hamilton. The principal localities visited were a 
couple of points on the line of the Lackawanna railroad, one a 
cut through a few feet of rock a mile and a half west of the village 
of East Bethany, the other the flat but narrow valley of a little 
brook crossing the railroad a mile and a half still farther west. A 
brick-yard by the highway, a mile south of the village, furnished 
good specimens of Spirifer marcyi and Tropidoleptiis carinatus, 
being the only locality where these two species were obtained. In 
the shales exhibited on the banks of a stream flowing through the 
same farm a fine crinoid was obtained, and in the banks of the 
same stream at a point nearer the village many small fossils were 
found in concretions of iron pyrites, among the most notable being 
specimens of Goniatifcs ttuiangnJaris. The water, however, was 
too high to permit a thorough examination of these shales, and 
far the larger portion of the collection was obtained from the 
slopes of the railroad cut and from low mounds of disintegrated 
material in the valley of the little brook first mentioned. 
The railway cut near East Bethany is from twelve to fifteen 
feet in depth, the encrinal limestone showing at the top of the 
slope. There is also a cut many feet deep at the crossing of the 
little brook to the west ; but the shales there exposed are appar- 
ently barren, except at the highest point, where a few large speci- 
mens of Spirifer granulosus, S. nmcronaHis and Athyris spirifer- 
aides w^ere found. At the bottom of this valley the encrinal lime-
