ONTARIO.

1. St. Catharines, Lincoln County.—In 1866 (Cat. Casts Foss., p. 37, fig.), Henry A. Ward represented a cast of an elephant tooth which appears to be the lower right hindermost molar. The original is stated to have been found at St. Catharines and to be in a museum at Niagara. It is possible that this is the tooth described on another page as Elephas columbi and now in the Victoria Museum at Toronto; but, while Ward’s figure represents the greater length of the tooth as worn, in the other tooth only 6 plates are worn. It is possible that the figure is incorrectly drawn.
2. Hamilton, Wentworth County.—In 1904 (Bull. Geol. Soc. Amer., vol. XV, p. 352), Coleman mentioned the finding of mammoth remains in a tunnel excavated through Burlington Heights, near Hamilton, and in a gravel-pit about a mile farther westward. A tusk and some bones were secured, but nothing by means of which the species may be identified. On page [147] is described the jaw of E. columbi, discovered at Burlington Heights. Logan (Geol. Canada, 1863, pp. 966, 967) illustrated the jaw just mentioned by two figures, 496, 498, of the symphysis of an elephant, found at Hamilton. Possibly this bone belonged to E. primigenius.
3. Toronto, York County.—In 1895 (Jour. Geol., vol. III, p. 641), Coleman reported that in 1894 a tooth of a mammoth had been found on Don River, north of Toronto, at a point where the stream flows over the middle till of the region and cuts away banks showing stratified sand and in some cases the upper till. The tooth may, therefore, belong to the interglacial beds, but possibly to the late glacial. In 1901 (Jour. Geol., vol. IX, p. 291), the same author indicated the possible occurrence of mammoth or mastodon in the Don Valley beds. This was recorded in 1900 (Rep. Brit. Assoc. Adv. Sci., p. 330). On page 300 (Jour. Geol., vol. IX) it is stated that an ulna of a mammoth or mastodon had been found in interglacial beds in Toronto, possibly in deposits representing the cold-climate Scarboro beds; but as it showed glacial scratches it may have been lying on the surface at the time of the Wisconsin ice advance. Even in the latter case the bone can, it would seem, be referred to an interglacial stage.
In 1899 (Ottawa Naturalist, vol. XII, p. 194), Coleman stated that teeth of mammoths had been discovered in a bar, a part of the Iroquois beach at York, east of Toronto.
