Male, winter coat.—As in other species of Cariacus, the winter 
coat is grey instead of tawny, the general colour being that 
commonly known as ‘ pepper-and-salt.” Behind the navel, as 
far as the penis, the colour is tawny rather than pure white. The 
tarsal gland is surrounded by blackish hairs, but outside of these, 
anteriorly, there are some white hairs. The surrounding area is 
tawny-grey. On the upper side of the tail the hairs are all dusky 
brown at the base and tawny at the tip. Legs grey. 
Skull. — Compared with C. virginianus, the forehead of C. 
clavatus is flatter. The level is maintained as far as the proximal 
end of nasals, beyond which it dips down, so that the nasal bones 
are more curved than those of C. virginianus. The skull is much 
deeper in front of the eyes in C. clavatus than in C. virginianus ; 
the eyes are larger, the lachrymal bone also larger and its free 
margin more convex, while the lachrymal pit is shallower. The 
orbital processes of the frontal and malar, forming the back 
of the orbital ring, are much the broadest in C. virginianus, and 
are more transverse. The pedicels of the antlers are directed 
upwards much more in C. clavatus than in C. virginianus. The 
tube of the exterior auditory meatus is much larger in the 
former than in the latter, and extends beyond the superlying 
ridge of the squamosal, so that it is plainly seen upon looking 
down upon the skull from above. The tube of the internal 
meatus is also prolonged in C. clavatus and ends in a sharp 
point. 
Antlers.—The antlers of young males of C. clavatus are 
simple, slightly curved spikes. The burr is small and moderately 
rugose. In a young individual from Tehuantepec, No. 9442, and 
in No. 14212, the antlers are more or less triangular in section. 
In the adult males, like No. 13038 from Costa Rica, the antlers 
are slightly lyrate, considerably compressed laterally, and sharply 
pointed. The burr, though broad, is in some cases not 
distinctly marked off from the beam, and the rugosities extend 
up the anterior surface of the latter along the basal two-thirds in 
antlers which are little worn. The right antler of No. 13038 is 
deformed, the beam being bent over backwards and downwards, 
so that the tip is on a line with the burr. In No. 13040 the 
antlers are abnormal; the beams are straight, slender, and 
smooth, and are distinctly marked off from the burr, somewhat 
as in the Roebuck (Capreolus). In. No. 14212 the antlers are of
