BOS LONGIFRONS. 511 
of the Bos longifrons describe a single short curve outwards 
and forwards in the plane of the forehead, rarely rising 
above that plane, more rarely sinking below it: the cores 
have a very rugged exterior, and are usually a little flat- 
tened at their upper part. 
Remains of this species were described by Robert Ball, 
Esq., Secretary to the Zoological Society of Dublin, in 
the ‘Proceedings of the Royal Irish Academy for Ja- 
nuary 1839,’ as indicating ‘‘a variety or race differing 
very remarkably from any previously described in works 
with which the author was acquainted.” They consisted 
principally of parts of the skull with the horn-cores, which 
had been found at considerable depths in bogs in West- 
meath, Tyrone, and Longford. 
In the same year Mr. Woods, in his ‘ Description of the 
Skull of the Bos primigenius from Melksham, gave a 
notice of a fragment of a skull, including the cores of the 
horns, with a wood-cut of the specimen, clearly showing 
it to belong to the Bos Jongifrons. It was found in a peat- 
bog in the neighbourhood of Bridgewater. This formation 
“covers an ancient sea-beach (although now nine miles 
from the coast), in which such marine genera as Murex, 
Ostrea, Mytilus, and Solen are abundantly embedded, and 
over these as plentiful a deposit of freshwater species, as 
Helix, Planorbis, Lymnea, &e., exhibiting the alternate 
resting of the sea, and a river or lake for very considerable 
periods.” The peat above these deposits is thirty feet in 
thickness, and the skull of the Bos longifrons was deeply 
embedded in it. 
The agreement of the specimens from the more ancient 
freshwater beds in Essex and Middlesex with those from 
the later formations of Devonshire and Ireland is ex-
