46 Professor MacGillivray on the Mammalia of the 
toe, shorter than the fifth, the second much longer, but shorter than the 
third, which scarcely exceeds the fourth; the sole bare, rugose, with 
six tubercles ; the claws slightly arched, compressed, acute; the hind feet 
longer, with the first toe much shorter than the fifth, the rest much 
longer, the second shorter than the third and fourth, which are equal ; 
the sole bare, with six dusky tubercles; the claws rather more slender 
than those of the fore feet ; the tarsi and toes are beautifully fringed with 
long, close, stiffish, decurved hairs; the tail is square at the base, gra- 
dually compressed beyond the first third of its length, higher in that 
space than in the basal region, and of nearly uniform breadth, tapering 
only when viewed from above or beneath, scaly, and covered with ad- 
pressed hairs, gradually decurved on the sides, and beneath ciliated with 
a ridge of stiffish oblique hairs, gradually becoming longer, and forming 
a point at the tip. 
The bare tip of the snout black, dusky beneath ; but the lips flesh- 
coloured ; the eyes black. The fur, which is close, soft, and velvety, like 
that of a mole, with extremely slender sparse hairs projecting beyond 
the general level, is, on all the upper parts, black, with the hairs bluish 
at the base ; immediately above, and a little behind each eye, is a small 
oblong white spot; and on the upper lobe of the ear is a tuft of white 
hairs. The lower parts are silvery-white, the two colours distinctly de- 
fined along the sides; but between the tail and the interfemoral space 
is a triangular patch of black, partly, however, intermixed with white 
hairs. The legs dusky externally ; the feet pale-grey above, becoming 
white on the toes; their bare parts beneath dusky flesh-colour, with the 
tubercles dusky; the ciliary hairs white, but on the outer side in part 
dusky ; the tail black, the hairs of the median ridge silvery-white. 
Canine teeth +, anterior molar 4, molar 4 = 3 = 80. 
In the upper jaw, the canine tooth bilobate, with the basal lobe small 
and compressed, the terminal lobe much elongated, obliquely compres- 
sed, decurved in the fourth of a circle, obtuse, but thin-edged at the end, 
curved inward, the two almost meeting near the tip. First small molar 
tooth anteriorly conical, obtuse, but thin, and curved inward ; second 
and third, similar, gradually smaller; fourth, minute, but similar. First 
grinder large, with two anterior external conical, obtuse, prominences ; 
the second larger, and a thin-edged ridge behind, terminating in a slight 
prominence, a little behind the anterior lobe internally is a small lobe, 
and nearly in a line with these two, an internal less elevated lobe, run- 
ning out behind. The second grinder with three external lobes, two 
internal, terminating the transverse grooves between the outer lobes, 
and two inner lobes or oblique protuberances within. The third grinder 
with three external nearly equal lobes, two internal lobes terminating 
the grooves, and two obtuse protuberances within. Fourth grinder very. 
small, transverse, with the crown irregularly concave, and two small 
prominences, the one anterior and external, the other posterior and thin. 
In the lower jaw, the canine tooth nearly horizontal, slender, obliquely 
compressed, thin-edged, with an elongated slightly elevated festoon, the 
tip a little ascending, obtuse, but thin-edged. The first false molar com- 
pressed, thin-edged, with an anterior elevated, obtuse, thin lobe; the 
second a little larger, similar, but with a second small lobe. The first 
grinder largest, with an anterior, two external, and twointernal points, 
the first external point largest; the second grinder similar; the third 
much smaller, but similar. 
The teeth are white, but with the tips brownish-red, that colour being 
chiefly confined to the inner processes in the upper grinders, and to the 
outer in the lower. 
The individual from which the above description is taken is an adult 
male, in perfect pile. It was caught at Knockleith, in Auchterless, and
