A posterior view of the cranium minus the mandible (as fig. 7, B, 
illustrates) brings out very well the odd implantation of the horns, 
basal width apart, and prominent postfrontal flattening. The orbits 
outlie squarely; and both the horns and horn-cores (¢) uprise 
boldly. 
(2) Component parts of the skull.—The long nasals abut against 
each other with a considerable convexity, toned down, however, by a 
flattening longitudinally of the summit of the arch. They are in- 
serted into the frontals by a semilunar naso-frontal suture ; and their 
outer margins from behind forwards are bounded respectively by the 
large suborbital fissures, maxillaries, and a small portion of the pre- 
maxillaries. As Turner notes, they are widest posteriorly ; towards 
their middle there is some lateral constriction, and forwards near 
their tips they gently broaden. The extremity of each is incised by 
a semilune, so that together, quite in front, they present a broad 
biconcave edge. 
In the top flattening of the nasals, their posterior width, and bifur- 
cate tips the Prongbuck follows the Deer and not the Antelopes. 
From the absence of a suborbital fossa, unusual extension forwards 
of the superior maxillary (Mz) and more than ordinary dilatation of 
its ascending or nasal process, the bone presents a remarkably pro- 
minent but throughout level cheek-surface ; and this gives rather a 
cylindrical contour to the rostral portion of the face. 
Whilst there is well-marked masseteric roughness, there is no 
ridge rising before the orbit, or only a very indistinct indication of 
such. The crescentie infraorbital foramen is large but low, and opens 
a little above in front of the first premolar. The anterior palatal por- 
tions of the maxille are characterized by the very elevated sharp 
ridge running from the alveolus forwards. 
A feature more akin to Deer than to Antelopes is the way in 
which the anterior palatal portion of the maxillary forks and em- 
braces the outer limb of the preemaxilla(Pmz). This is more marked 
in some Prongbuck skulls than in others ; but in all the coadaptation 
of the bones, or the sutural line, manifests cervine instead of bovine 
construction. 
In Deer the upper canine tooth is implanted in the said fork or 
angle; and though, in the adult Cabrit, there is no such tooth ex- 
tant, yet the bifurcation of the bone may be interpreted as a fore- 
shadowing of the Stag’s dental development. 
Each preemaxilla is of a fair size; and its ascending limb articu- 
lates with and between the nasal and maxillary, in a narrow wedge- 
form an inch or so in length. The ascending or outer limb is nar- 
rowish throughout, the horizontal or inner one slender, and their 
flattish anterior angle of junction moderately expanded. 
The jugal or malar bone (Jw), 3 inches long and 1j in greatest 
depth, offers an elliptical outline, a large portion of which constitutes 
a cheek-buttress. The zygomatic splint posterior to the orbit agrees 
with that of the Chamois in its uncommon shortness. The segment 
of the lachrymal contributing to the orbital ring forms no more 
than an eighth of the cireuit; here the lachrymal is broadest, ta-
