black and disposed in pairs on the back; in the male speeimen 

 the foremost pair is fused together into a large transversal 

 hour-glass-shaped spöt immediately behind the ossification 

 of the liead; as shown by the figure, these spöts are separated 

 and placed at some distance behind the posterior börder of the 

 ossification in the female. The parts around the opening 

 of the dorsal pouch of the female are dotted with pink. In 

 both sexes there is behind the shoulder a longitudinal curved 

 brown spöt, bordered with black and surrounded by white. 

 This spöt is continued into a black stripe above the tympanum, 

 extending along the börder of the upper eyelid and the canthus 

 rostralis to the tip of the snout. where it joins its fellow. The

 surfaces of the head green with some small dark döts in the 

 male. The outermost rim of the upper lip is black and bordered 

 above by a narrow white Hne. The sides of the body like the 

 upper parts but are sprinlded with white. The under surfaces 

 are uniform yellowish white, the throat and the chin being 

 lighter than the belly. The colour of the extremities corres- 

 ponds with that of the body; the upper parts ha ve regular 

 brown crossbands, bordered with black. The tympanum is 

 blackish brown. According to a note of the collector, Dr. 

 P. DusÉN, the animals agree, when alive, very well with the 

 ground where they Ii ve, and are very difficult to discern.
