Description. — There follows a free translation of the original 

 description: 



Body form rather stout. Vomerine teeth lacking. Choanae very small, 

 lying close by the border of the jaw. Tongue rather large, pear-shaped, free and 

 entire posteriorly, without papillae. Head rather large, longer than broad; 

 snout pointed when seen from above and in profile, projecting over the mouth 

 opening, as long as the rather large eye, equal to the distance between the upper 

 eyelids anteriorly, longer than high; canthus rostralis rounded but distinctly 

 curved; loreal region descending perpendicularly, concave; nostril somewhat 

 projecting, nearer to tip of snout than to eye; distance between nostrils less than 

 interorbital diameter, which is twice the width of the upper eyelid; tympanum 

 entirely hidden under the skin. Fingers short, free, first shorter than second, 

 which is shorter than fourth; no disks; no rudiment of a pollex; subarticular 

 tubercles distinct; palm of hand set with tubercles. Toes rather long, free of 

 webs; disks very small but distinct, lancet-shaped, pointed anteriorly, third a 

 little longer than fifth; lateral metatarsals strongly united; lateral toes without 

 a skinfold; tarsal fold lacking; a small, rather long median and a smaller, longish- 

 oval lateral metatarsal tubercle; no tarsal tubercles. Sole of foot smooth; sub- 

 articular tubercles small but distinct. When hind leg is adpressed, heel reaches 

 betv/een eye and tip of snout; femur shorter than tibia, which is three times as 

 long as broad, contained a little less than twice in the body length, and much 

 longer than foot. When legs are placed at right angles to the body, the heels 

 cover each other. Upper parts of head, body, and limbs thickly set with small 

 granules and tubercles, which in the region of the nape of the neck run together 

 in two concave curved strips, and on the sides of the back run into the dorsolateral 

 folds; upper part of tibia with diagonal strips formed of uniting tubercles. Throat 

 and breast smooth; belly very faintly granulated; underside of femur coarsely 

 granulated. Color in alcohol: Very dark grayish-brown, becoming still darker 

 on the head, almost black on the snout. Limbs with indistinct light diagonal
