Structure of the hair
---------------------
The microscopic structure of the skin
surface is furrowed, the hair follicles are
narrow with straight edges and contain only
one hair shaft.
The fine fur fibres are from 8 to 17 µm The cuticular structure
in diameter. The cross-section is circular of the fine fibres, 3000x
or elliptical and the cuticle is built from
cornet-like scales having very wide upper edges. The cuticular surface is
finely grooved and the edges of the scales are straight. The fine fur fibres
have no medullary column.

The intermediate fibres are circular at
the bottom, but elliptical in the main part
if the hair. The cuticular scales are
cornet-like in the lower part, and
comb-like in the upper part. The scale
surface is finely grooved; the scale
margins are straight. Also these hairs are
non-medullated. The cuticular structure

The guard hairs are elliptical in cross-
section and their diameter is 25 to 45 µm. The cuticular scales are rounded,
tile-like and comb-like, with a grooved scale surface and straight scale
margins. These fibres are non-medullated, similar to other fibres of this
animal.
