VEKTEBEATA ont été trouvés qui décrivent un cercle, mais la courbe étant oblique, ils ont donc clairement la tête et pointent vers l'extérieur, vers le bas et vers l'arrière. Le crâne de l'Elephas primigenius est allongé et le front contre-batteur. Une molaire inférieure peut être distingué d'un supérieur par la surface de broyage étant légèrement concave dans le sens de sa plus longue, diamètre de la molaire supérieure que d'être dans le même degré convexe.

. Catalogue of casts of fossils, from the principal museums of Europe and America, with short descriptions and illustrations. Fossils. 36 VEKTEBEATA. have been found which describe a circle, but the curve being oblique, they thus clear the head, and point outward, downward and backward. The cranium of the Elephas primigenius is elongated and the forehead concave. A lower molar can be distinguished from an upper one by the grinding surface being slightly concave in the direction of its longest diameter, that of the upper molar being in the same degree convex. Most of the molars of the New World Mammoth are character- ized by thinner and more numerous plates than those of England, but the differ- ence is not constant. The creature was covered with shaggy hair, so that it was fitted to live as near the pole as is compatible with the growth of hardy trees or shrubs. The sterile region in Northern Siberia, where the remains occur so abun- dantly, was, according to Murchison, beneath the sea at the period when the Mam- moth lived; the bones and carcases therefore must have drifted thither. It should be mentioned, however, that the remains are rarely rolled or water-worn. This lower jaw, belonging to a young animal, was disinterred from a Pleistocene deposit at Lippe, Rhenish Prussia, and is in the University Museum at Bonn, Rhine Val- ley. It is a very perfect specimen, and retains the molar teeth in place. Size, 12 x 12. Price, $3.00. No. 133. Elephas primigenius, Blum. Lower Jaw, young. This specimen was found in 1835, in a Pleistocene de- posit in the Department of Ain, France, and is now in the Museum of Natural History at Lyons. Size, 12 x 10. Price, $3.00. No. 134. Elephas intermedins. Lower Jaw. This specimen is from the Pleistocene in the Parish of Eculy, near Lyons, France, and is in the Mtiseum of that city. Size, 2 ft. 3 in. x 25 in. Price, $8.00. No. 135. Elephas intermedins. Lower Jaw. This jaw was found in the Pleistocene at Lyons, and is in the Museum of th
