2. _Alton, Madison County._—The U. S. National Museum contains a fragment of a molar of apparently _Megalonyx jeffersonii_, from a collection made long ago by William McAdams, at Alton, Illinois. It has on it McAdams’s number 21. This collection, which was long in the hands of Professor O. C. Marsh, as vertebrate palæontologist of the U. S. Geological Survey, is said to have been made in the loess at Alton. Most of the teeth, with occasional bones, are inclosed in nodules of extremely fine sand and carbonate of calcium so hard that the teeth can not be removed without injury. They have been, however, partly exposed by weathering. The nodules which contained the fossils were found between the loess and the underlying Illinoian drift. The fragment of a megalonyx tooth has the diameters respectively 16 mm. and 24 mm. It is thinner fore-and-aft than other specimens, but this may be an individual variation. It is believed that this loess belongs to the Sangamon interglacial stage. The geology of the locality and the species found there are discussed on page 339. Also, the fossils were described by the writer in 1920 (Proc. U. S. Nat. Mus., vol. LVIII, pp. 109–117). The presence of this sloth-like beast appears to indicate that the climate was at that time mild. 3. _Galena, Jo Daviess County._—In 1870 (Proc. Acad. Nat. Sci. Phila., 1870, p. 13), Dr. Leidy brought to the notice of the Academy the fossil remains of two species of much interest. These had been presented to the Academy by Henry Green, of Elizabeth, Jo Daviess County, and were reported as having been found in a narrow crevice of the lead-bearing rocks in the vicinity of Galena, at a depth of 130 feet. One fossil was a metacarpal bone of _Megalonyx jeffersonii_, the other was identified as a last lower molar of _Bison antiquus_. Leidy mentioned three other species, _Platygonus compressus_, _Procyon priscus_, and _Anomodon snyderi_ as having been found about Galena in similar situations. The geological age of the Vertebrata found in the lead crevices about Galena has not been well determined, but the present writer has regarded them as being probably of late Wisconsin time. The _Bison_ tooth may have been that of the yet existing species. However, the possibility is that these fossils are pre-Wisconsin. VIRGINIA. (Map 3.) 1. _Saltville, Smyth County._—Mr. O. A. Peterson, in 1917 (Ann. Carnegie Mus., vol. XI, p. 472, figs. 4, 5), reported the discovery of the symphyseal portion of the lower jaw of _Megalonyx_ at Saltville. It was referred with some doubt to _M. dissimilis_ Leidy. Further mention of the specimen will be made on page 352. 2. _Ivanhoe, Wythe County._—On a page devoted to the consideration of a considerable number of species found by Cope near Ivanhoe, in Wythe County, mention will be made of _Megalonyx jeffersonii_. Only fragments of teeth were secured by Cope. WEST VIRGINIA.
