84 : NOTICE OF REMAINS OF THE WALRUS 
The form of the facial portion of this specimen corresponds with that of the specimen 
from Virginia, above mentioned; and the entire skull closely resembles that of the recent 
Walrus, Zrichecus rosmarus, as represented in the figures of Daubenton, Cuvier, and De 
Blainville; and its measurements also are sufficiently near those given by the first named 
author to recognise it as the same species.* 
The tusks in the fossil curved downwardly in a diverging manner, and were about four 
inches distant from each other at their emergence from the alveoli, and ten inches at their 
tips. The remaining tusk in the specimen, is thirteen inches long from its alveolar bor- 
der, and in this latter position it is three inches in diameter antero-posteriorly and one 
and three-quarter inches transversely. 
The second incisor, and the succeeding three molar teeth, contained in the specimen, 
occupy an extent antero-posteriorly of four and a quarter inches. These teeth are quad- 
rately rounded at their alveolar orifices, and are worn away at their triturating surfaces 
in an irregularly oblique manner. The first molar tooth is the smallest of the series; 
and the incisor and the other molars are of nearly equal size. 
Quite recently Professor Geo. H. Cook, of New Brunswick, New Jersey, sent for my 
inspection, the facial portion of a Walrus skull, which also was discovered on the sea beach 
of Long Branch, New Jersey. The specimen was kindly loaned to Professor Cook by 
the Rev. Mr. Finch, of Shrewsbury, to whom it now belongs. It is unchanged from its 
original texture, but is brown from the infiltration of oxide of iron. It also belonged to an 
old individual, as all the sutures are obliterated, and the third molars together with the 
greater extent of their alveoli are gone. (PI. IV., fig.2.) In its anatomical details the 
specimen agrees with the corresponding portion of Professor Frazer's specimen, except 
that it is an inch and a half broader in the position of the canine alveoli, and the antero- 
posterior diameter of the tusks is rather less. 
An important question now arises in relation to the age or geological period to which 
the three Walrus skulls, thus discovered on the coasts of New Jersey and Virginia, belong. 
As they appear to be of the same species as the recent Trichecus rosmarus, which once 
lived in great numbers in the Gulf of St. Lawrence, they are most probably the re- 
mains of individuals that were once floated upon fields of ice southerly, and left on the 
present United States coast. Or, perhaps they may be the remains of the same species 
which probably during the glacial period extended its habitation very far south of the 
latitude in which it has been found in the historic age.
