white, and the hairs on these parts are uniform to the root: 
a well defined Mack mark extends along the back, commenc¬ 
ing in a point over tho shoulders, and terminating about, 
half way down tho hack: on tho cheeks is a whitish mark, 
which has its origin on the upper lip, and terminates beneath 
the eve: tho ears are clothed internally with whitish lmirs, 
• # 
and externally, at the base, with hairs of the same rusty grey 
tint as those of the head; but, at the apical portion of the 
ear, the hairs are shorter, and of a dusky colour: the fore and 
hind feet have the toes brownish black ; the tarsi are whitish 
behind, but freely pencilled with dark brown on the anterior 
half; the tail is as long as the body, grey above, and of a 
dirty yellowish tint beneath; rather sparingly clothed above 
with short stiff hairs, which do not perfectly hide the scales, 
these being usually developed on this organ in inverse pro¬ 
portion to the hairs; on the under surface die hairs are 
longer, and more dense; an indistinct whitish mark crosses 
the haunches externally. The foremost iucisor tooth of the 
upper jaw is nearly twice as broad as die second, and the 
third is rather broader than the first; it has a vertical groove 
in the middle of the outer surface, or perhaps even slightly.in 
advance of the middle line—see Plate 5, fig. 14.

Fine male specimens somedmes exceed these dimensions, 
being about flO inches in length from the nose to the root of 
the tail; and the females usually furnish dimensions rather 
less than those above given. A skull of a male specimen of 
M. dorsalis, in Mr. Gould’s collection, presents the following 
dimensions:—
