may presume therefore to have been derived from the 
subjugation of a native species of Bos. 
In this field of conjecture, the most probable one will 
be admitted to be that which points to the Bos longifrons 
as the species which would be domesticated by the ab- 
origines of Britain before the Roman invasion. Had the 
Bos primigenius been the source, we might have expected 
the Highland and Welsh cattle to have retained some of 
the characteristics of their great progenitors, and to have 
been distinguished from other domestic breeds by their 
superior size and the length of their horns. The kyloes 
and the runts are, on the contrary, remarkable for their 
small size, and are characterised either by short horns, as 
in the Bos longifrons, or by the entire absence of these 
weapons. 
ADDENDUM TO BOVID. 
The valuable geological services rendered to the Russian 
Empire by our distinguished countryman, Roderick Impey 
Murchison, Esq., have been the source of reciprocal bene- 
fit to Zoological science at home, the Emperor of Russia 
having been pleased, at Mr. Murchison’s request, to direct 
the transmission to this country of the prepared skin and 
the skeleton of the rare Zubr, or existing Wild Aurochs, 
which species is preserved with so much care in the forests 
of Lithuania. The specimens have been presented by 
his Imperial Majesty to the British Museum, where I 
have had the opportunity of comparing the recent bones 
with those of the fossil Aurochs since the foregoing sheets 
went to press. 
The metacarpal and metatarsal bones present the same
