 deep black patch present along their external bases, succeeded 

 posteriorly by a prominent white or pale yellow spot. Hairs of 

 back slaty grey, their tips nearly white, except along the central 

 dorsal streak, which ends between the hips. Upper surface of 

 parachute dark brown or greyish, its edges fringed with white or 

 pale yellow. Whole of underside and inner sides of limbs white, with
