Crown of the head without projecting ridges, the interorbital space being slightly 
concave and wider than the supraciliary cover. Snout short, with vertical sides and 
sharp canthus rostralis, truncated in front. Tympanum distinct, about half the area 
of the eye. Parotoids large, with an angular ridge which extends forward over the 
terms :—Supraorbital ridges slightly developed; internal nares of moderate size; tongue elongate, cordiform, 
rounded posteriorly, free for rather more than half of its length posteriorly ; colour grey, with a longitudinal 
row of subround black spots on either side of the median line; extremities varied with black; underparts 
yellow, marbled with black. 
* It should be borne in mind that in young specimens these cranial crests are much less developed than in 
mature ones, and entirely absent at a very early age.
