BRITISH FOSSIL ELEPHANTS. 
dicular anterior border. It is a suggestive fragment as compared with the preceding, 
especially with reference to the absolute and relative heights of the horizontal ramus at 
the commencement of the diasteme, and of the ascending ramus, as indicated in discussing 
the characters of jaw (No. 215 a). 
In the collection of R. Pitch, Esq., there is a fragment of a right ramus of the lower 
jaw, with a last true molar in place. The tooth is much worn in front, but its heel is 
rounded, and there is no mark of pressure, although it is much advanced in wear, seeing 
that the posterior talon is in line with the anterior border of the coronoid. 
. There are ten ridges in wear, with a loss by detrition in front. The elements present 
the same characters as in the foregoing. The molar is 9 J X 3 inches. 
These characters are, in fact, even more pronounced than in the jaws in the Gunn 
Collection, to wit, a gradually descending diasteme into the beak, whilst the height of the 
horizontal ramus at the commencement of the diasteme is 8 inches, and at the insertion 
of the coronoid it is 7 inches. But the jaw, although low in height, is of great breadth, 
being 5 inches in width at the heel of the molar. The length of the symphysial 
gutter is 4J, and its breadth in front 2f- inches, with an internal foramen near the latter. 
Another right ramus of a mandible from Bacton, Norfolk, is in the possession of 
Randall Johnson, Esq., of Stalham. It displays a fragment of the second, with the last 
true molar just commencing wear. The fragment is nearly entire, with the loss only of 
the condyles and coronoid. 
Here, again, the diasteme slopes gradually into the beak, and is 6 inches in length. 
The height at the commencement of the former is 7inches, and at the insertion of 
the coronoid G inches. 
The dental canal looks upwards and backwards, as in No. 215 a, Gunn Collection, 
just described. 
The entire characters of this jaw are in accord with the preceding, but the last molar 
is unfortunately half hidden posteriorly; however, the first fragment of the second molar is 
undistinguishable from the teeth already noticed as regards the channellings of the 
enamel, absence of pronounced crimping, and the presence of large wedges of cement. 
A specimen (No. 28 of the Woodwardian Collection) is fragmentary. It is a right 
ramus lower jaw with portion of an ultimate molar in position. There is a loss of 
substance immediately behind the molar. The diasteme is injured, and has been partly 
restored with plaster. 
The crown of this molar is arcuated; it holds 11 a? in 9x3j inches. There is 
slight crimping of the machaerides, and the cement between the plates is much denuded, 
so that the discs appear as if raised much above the general level of the crown. The 
height of the jaw at the commencement of the diasteme is 6^ inches. 
The worn discs, as far as they go, are in support of the characters of A. meridionalis 
rather than the broad crown of E. antiquus. The specimen was presented by Miss A. 
Gurney, and is from the Norfolk coast.
