See here.

Under the 4th section of this page is the following: The badge was a horse rampant in a circle on which was the unit's title; above the circle was a crown and below it a scroll with the motto "Virtus in Arduis".
Except that this badge appears to be a wolf's head erased rather than a horse rampant.
