 broader, and of an oval form. The colour is lighter ; the muzzle, 

 lower parts of the head and body and the sides of the tail are 

 white ; the upper parts of the snout, head, and body are of a 

 lilac colour, covered with numerous round white spots. The 

 foliated appendages and the end of the tail are black.
