From the anterior view also the rhinaria ofthe two species are much alike, except that in D. horribilis the Fur. A. Rhinarium and upper lip of Helardos malayanus from the front. B.

Moreover, the medianarea of the upper lip below the rhinarium is scantily rhinarium, however, is everywhere sharply circumscribed.
