angle is obtuse in the bison ; finally that plane of the occiput is 
quadrangular in the ox but semi-circular in the bison.” 
Remains of the species are found in the forest-bed, and dredged 
from the post-glacial deposits on the coasts. 
This species seems to have been the direct ancestor of the 
Lithuanian aurochs now strictly preserved in the forests of 
Lithuania. 
Genus BOS. 
B. primigenius (Bojanus). — Dos primigenius differs from the 
Bison priscus for the reasons mentioned above, as well as by the 
greater length of its horns. It seems to have been equal in size if 
not even superior to Bison priscus. It seems to have existed down 
to the historical period, as it is mentioned under the name of 
Unis by Caesar, as existing in bis day in the great Ilercynian 
forest. It is also mentioned in an old German ballad of the 
twelfth century as having been slain with other animals, in a 
great hunt which took place in the forest of Worms. 
The fino skulls and horn cores in the Norwich Museum, were 
obtained from the peat in cutting the North AValsham and Dilham 
canal. 
B. longifuons (Owen). — This species differs from Bos primigenius 
in its great inferiority of size. The horn cores are also much smaller 
and shorter, as well as differently directed; the forehead is less 
concave, in fact nearly flat ; the frontal bones extend further 
beyond the orbits before they join the nasals. 
Professor Bell in his ‘British Quadrupeds,’ page 414, seems to 
think that, Bos primigenius was the probable ancestor of our present 
domestic ox. It seems, however, more reasonable to suppose that 
Bos longifrons was the ancestor, for this reason : Bos long if eons is 
known to have been domesticated. It is found associated with 
the works of man in the Neolithic interments, as well as the 
later Romano-British burial grounds. The associated mammalia 
are the pig, goat, dog, which were no doubt kept in a state of 
domestication by the early races of man that inhabited western 
Europe. 
This species is found in the alluvial deposits in Norfolk, and, in 
fact, often on the present surface of the land.
