18 PROCEEDINGS OF THE GEOLOGICAL sociETy. [June 16, 
Amongst the earliest examples received of this order were molar 
teeth of a true Paleotherium. 
Lower molar. 
a 
Upper true molar. Palzotherium medium ? 
Paleotherium medium ? 
A single fragment of an upper molar tooth (fig. 1), with the outer 
side of the crown broken away at the enamel-line, like the letter W, 
but including the imner half with the oblique peninsular fold (e) and 
island (e') of enamel, and the two parallel oblique tracts of dente, 7’, 2, 
presents the typical characters of the upper molars of the genus Paleo- 
therium: it was the first evidence of that genus which I had seen from a 
formation of what, in relation to the Isle of Wight, may be termed con- 
tinental England. The tooth, when entire, has agreed with the first 
of the three true molars in fig. 14. pl. 47. and fig. 1. pl. 56. of the 
‘Ossemens Fossiles,’ tom. ii. The ridge 7 at the fore part of the 
base of the tooth, and the short ridge e closing the entry to the 
oblique fold or valley, are present, as in the true Paleotheres. The 
tooth is smaller than the upper molar represented in fig. 3. pl. 4. 
tom. cit., and can only be referred to the Paleotherium medium as 
represented in the other plates above-cited, from the immortal work 
of Cuvier. Some lower molar teeth (figs. 2 & 3) also exhibited all 
the typical characters of that part of the genus Paleotherium: viz. 
the two semicylindrical lobes, 0, 0, the single pomt at the reunion of 
their contiguous angles to form the middle lobe on the imner side of 
the crown (2), and the basal ridge (7) : this is divided into an external 
and an internal portion, both of which send their anterior and poste- 
rior extremities obliquely upwards to corresponding angles of the two 
lobes. The crown is supported by two strong and long fangs grooved 
longitudinally on the sides turned towards each other, and with a 
thick coat of cement at their base, ec. The tooth figured was much 
worn; it is but a millimeter less im antero-posterior extent than the 
penultimate molar of the Paleotherium medium, in the portion of 
lower jaw, fig. 2. pl. 42. of the ‘Ossemens Fossiles,’ t. 1. It is three 
millimeters shorter in the same dimension than the corresponding 
tooth in the lower jaw figured in pl. 40. fig. 1, t. cit., which is also 
referred by Cuvier to the Pal. medium. 
Soon after receiving these, the first evidences of a proper English 
Paleotherium, Mr. Pytts Falconer transmitted to me from the same
