1. Trenton, Mercer County.—Mr. Ernest Volk (Papers Peabody Mus., vol. V, 1911, p. 209, plate CXX) reported the discovery of a part of a femur of Bison (probably B. bison) in the “yellow drift,” at Trenton, 2.5 feet from the surface. A first right upper molar, identified as that of Bison, was found in another sand-pit at a depth of 9 feet (op. cit., p. 136). This appears to have belonged in the Trenton gravel, but at that point the materials were apparently a mixture of sand and loam. The reader is referred to page 304, where the geology of this locality is described and a list of the species is given.
