Supraorbital ridges very prominent, not crenate, presenting a posterior process. Postorbital and supra-tympanic processes prominent, obtuse; preorbital straight, more acute. Canthus rostrales acute, converging so as to produce a very acute angle; their profile very declive, that of the muzzle more so, but not perpendicular. Maxillary region oblique from a front view; the labial border forming a prominent rim, which is thickened and everted posteriorly. Two occipital knobs on each side. Tympanum small, one-fourth or one-third the length of the palpebral border in diameter. Paratoid gland small, rounded, lateral, studded with warts; the dorsal region is similarly studded, most abundantly anteriorly. Sides, extremities and gular region covered with smaller warts; belly areolate. One large oval flat metacarpal tubercle; a large one at the base of the interior digit. Two metatarsal tubercles; the interior most elongate and acute, blackish brown. A short, thickened, internal tarsal fold. Toes half-webbed, palm slightly rugose.
Length from end of muzzle to tympanum 11 lines; of antebrachium and hand, 14.5 lines; axilla to vent, 2 inches; vent to end of fourth toe, 3 inches 1 line.
The head is brown; color elsewhere brownish yellow; on the nape and sides marbled with deep brown, somewhat oblique-longitudinally on the latter region. Limbs cross-banded with brown.
