When engaged in reconnaissance work in Saratoga County, New York, during the summer of 1878 I found a small group of fossils in a thick-bedded, hard gray siliceous limestone at Hoyts quarry, 4 miles west of Saratoga Springs. The limestone and included fossils were referred to the "Califerous formation" and attention called to the relation of the Hoyt quarry fauna to that of the "Potsdam sandstone of Iowa and Wisconsin." The species described were Platyceras minutissima, Metoptoma cornutaforme, Conocephalites calciferus, C. hartti, and Ptychaspis speciosus. Subsequently drawings were prepared illustrating the species and a large plate was made up, photographed, and distributed to a few investigators in July, 1885. In 1890 several additional species were described from the Hoyt quarry and illustrated and referred to the Upper Cambrian. These included Platyceras hoyti, Trochus ? saratogensis, and Agraulos saratogensis. At various times in 1886 and 1888 I made brief visits to different localities about the Adirondack Mountains, New York, where the Potsdam sandstone member of the series was exposed. The results of these observations were included in a summary published in 1891 of the Cambrian formations of the Adirondack subprovince, reference being made to the fossils found. In 1903 the name "Saratogian" was proposed for the formations and contained faunas then referred to the Upper Cambrian.
