 projecting beyond the mouth, as long as the eye or a little shorter; 

 canthus rostralis obtuse; loreal region moderately oblique, concave; 

 eye rather small ; nostril equidistant from the eye and from the tip of 

 the snout; distance between the nostril, equal to the interorbital 

 width, which is equal to or slightly less than that of the upper eyelid; 

 tympanum feebly distinct, ill-defined, with small asperities as on the 

 neighboring region, f to i the diameter of the eye, once to twice its 

 distance from the latter. 



Fingers moderate, the tips feebly swollen, first longer than the 

 second (exceptionally first and second equal), third longer than the 

 snout; subarticular tubercles moderate or rather large, prominent. 



Hind limb long, the tibio-tarsal articulation reaching the tip of 

 the snout or beyond, the heels overlapping when the limbs are folded 

 at right angles to the body; tibia 4 to 6 times as long as broad, 1|- to 

 1% times in length from snout to vent, shorter than the fore limb, as 

 long as or a little longer than the foot. Toes with the tips swollen 

 into small disks, the base of which is involved in the very broad web; 

 outer metatarsals separated nearly to the base; subarticular tubercles 

 rather large and prominent; no tarsal fold; inner metatarsal tubercle 

 oval or elliptic, f to f the length of the inner toe; a round outer meta- 

 tarsal tubercle. 



Skin of upper parts more or less granular, pustular, and porous, 

 sprinkled all over with small horny granules, often with large porous 

 warts on the sides; dorso-lateral fold, if distinct, very broad and flat 

 and confined to the anterior half of the body; a fold from the eye to 

 the shoulder; one or two large glands behind the angle of the mouth; 

 lower parts smooth, except the hinder half of the thighs which is 

 covered with flat granules, some of which show a more or less distinct 

 large central pore or pit. 



Grayish brown to dark olive brown above (sometimes brick, and 

 according to Miss Dickerson), usually with a dark cross-band between 

 the eyes, numerous small darker spots on the body and more or less 

 distinct dark cross-bands on the limbs; upper surface of snout some- 

 times paler than the rest of the head; often an oblique light streak 

 below the eye; hinder side of thighs yellow, spotted or marbled with 

 black; web between the toes yellow. Lower parts white in front and
