cranium, and the intercornual ridge consequently then forms an almost unbroken 
arch. At the upper part of the forehead, the frontals slope slightly backwards to 
join the intercornual ridge, which is placed rather behind the plane of the face ; this 
ridge is produced ujowards and backwards so as to overarch to a considerable extent 
that part of the occipital surface intended for the attachment of the vertebro- cranial 
muscles ; from its highest point the intercornual ridge slopes gradually downwards 
and backwards to join the occipital crest ; the surface of that part of the occiput 
which is above the crest being in consequence placed posteriorly to that part which 
is below the crest. The occipital crest itself forms a continuous and unbroken arch, 
which is separated by a considerable interval from the intercornual ridge. The 
paroccipital process of either side is separated by a deep groove from the occipital 
condyle. The bases of the horn-cores do not extend more than one-and-a-half inches 
below the highest point of the occipital crest or curved line ; and there is a wide 
interval between the former and the lateral borders of the crest. The temporal 
fossae form small triangular notches immediately below the bases of the horn-cores 
on the occipital surface ; the plane of the latter forms an acute angle with the plane 
of the frontals. The palate is in too imperfect a condition for accurate description ; 
it is, however, but slightly produced backwards behind the molar series, and the 
line of the latter is very concave internally ; the basioccipital is triangular in form 
as in the typical oxen, and carries four tubercles for muscular attachment, of which 
the posterior pair are the .larger and are separated by a wider interval than are the 
anterior pair. 
The horn-cores are placed on the liighest ridge of the skull, immediately above 
the plane of the occiput ; in cross section {FI. XI, figs. 3 8f 4) they are nearly circu- 
lar in the middle, hut have a slight ridge along their superior border ; at their base 
they are somewhat slightly compressed from side to side, the cross section being pear- 
shaped at this point ; they diminish in width very gradually ; their direction is at 
first upwards, outwards, and slightly forwards, then nearly directly forwards, and 
finally inwards and slightly upwards ; at their extremities they are placed at a dis- 
tance of nearly two feet in advance of the plane of the frontals. The measurements
