from the oolitic slate of Stonesfield, Oxfordshire, for which the name of 
Stereognathus ooliticus had been proposed; and after a minute descrip- 
sub-compressed : the outermost and innermost of the three hinder ones 
are oblique, and converge towards the middle of the crown, being over- 
lapped by the outermost and innermost of the three front cones. The three 
molar teeth occupy the extent of 44 lines, or 1 centimeter; each tooth 
being 3 millimeters in fore and aft extent, and nearly 4 millimeters in 
transverse extent. er a comparison of these molars with the multi- 
cuspic teeth of the rat, the hedgehog, the shrews and Galeopitheci, the

examinations of additional specimens of jaws and teeth of the Dichodon 
cuspidatus, which he had received since his original Memoirs on that ex- 
tinct animal in the Quarterly Journal of the Geological Society, vol. iv 
(June, 1847), The first specimen described supplied the characters of the 
last true molar tooth of the lower jaw, which had not been previously 
nown. This tooth has six lobes, the additional posterior pair being less 
than the normal ones, and more simple. The inner surface of the inner 
lobe has an accessary cusp at the back part of its base, but not at the fore 
a in the other lobes. The length of the last lower molar was nine 
that of the first and second molars being each six lines. A speci- 
men of the Dichodon cuspidatus from the Hordwell Sands, in the British 
Museum, supplied the characters of the permanent incisors, canine, and 
three anterior premolars of the upper jaw : all these teeth closely corres-
