2. Skidaway Island, near Savannah, Chatham County.—On page 27 of William B. Hodgson’s “Memoir on the Megatherium,” in Joseph Habersham’s memorandum, is noted the fact that among the fossils found here was a well-preserved tooth of a horse. The height of the tooth is given as being 2.75 inches, greatest diameter 1.2 inches, the least 1 inch. The tooth was evidently an upper premolar or molar. It belonged probably either to Equus complicatus or E. leidyi, but to which is uncertain.
In 1850 (Proc. Amer. Assoc. Adv. Sci., vol. III, p. 67), Robert W. Gibbes reported the discovery of horse remains, probably a tooth, in the alluvium of Skidaway Island, a few miles southeast of Savannah. No further information was furnished. The geological conditions at this island and the fossils found there will be considered on pages [370] to [372].

1. Stokes Ferry, St. Mary’s River, Nassau County.—In 1909 (2d Ann. Rep. Florida Geol. Surv., p. 147), Sellards stated, on authority of notes received from Dr. L. W. Stephenson, that 3 teeth of a fossil horse had been found at the place named. At the same place was discovered a fragment of a tooth of an elephant, most probably Elephas columbi, and some ear-bones of a whale. The writer has not seen these and does not know to what species they belonged.

2. Almero Farm, St. John County.—In the collection of Mr. Fred R. Allen, of St. Augustine, Florida, the writer has examined a left tibia of an extinct horse, found in the Inland Waterway Canal, about 28 miles south of St. Augustine. The species has not been determined, but it may be well to put on record the measurements. It apparently belonged to a rather large horse. For comparison, other corresponding measurements are given, taken from Equus scotti, No. 10628 of the American Museum of Natural History, and from Equus caballus, No. 74 of Mr. Chubb’s collection at the museum mentioned, a trotting stallion.
It will be seen that the tibia found below St. Augustine is a relatively stouter bone than those it is compared with. The large horse, known to have existed in Florida, is Equus complicatus.
3. Neals, Alachua County.—This place is near Newberry. Here have been collected Gomphotherium floridanum, Tapirus terrestris?, and Hipparion sp. indet.
4. Wade, Alachua County.—The writer has seen at Tallahassee, 4 fossil Equus teeth, found at this place. One is No. 1470 of the Florida Geological Survey and labeled as found in the Buttgenbach “cummer” mine. It is a lower left second premolar, 40 mm. high, 31 mm. long, and 14.5 mm. wide, not including the cement present. Another tooth, No. 1462, from Buttgenbach’s river mine, near Wade, is the hindermost left molar of the lower jaw, 32 mm. long, and 13 mm. wide in front. It is thought these teeth belonged to Equus leidyi.
