Description of tgpe.—Body slender and dorso-ventrally depressed; head scarcely longer than broad, depressed; slightly projecting beyond the mouth, and longer than the length of the eye; canthus rostralis obtuse; loreal region oblique, concave; nostril nearer to the tip of the snout than to the anterior border of the eye; interorbital space as broad as the space between the nostrils ans greater than the width of the upper eyelid; tympanum hidden;jaws rather weak; no vomerine teeth; novocal sacs in the male. Fingers long and rather slender (fig.21,B),the first as long as the second,with light-colored nuptial pads on the inner dorsal sides; the fourth finger longer than the first and second but much more slender; the third the longest and alsoslender; subarticular tubercles indistinct; palmar tubercles developed but very flat; tips of fingers lighter in color.' Hind limb short and weak, its length 125 per cent of the body length, thetibio-tarsal articulation reaching the base of the arm, the heels mot meeting when placed at right angles to the body; tibia 38 per cent of the body length; toes (fig.21,C) slightly fringed, their tips rounded and slightly dilated,the two inner toes about one-thitd webbed at base; subarticular tubercles present but indistinct; u\inner metatarsal tubercle elongated, with a free edge, outer metatarsaltubercle wanting, Skin rough,with many large large and small pitted warts, more or less evenly distributed on the back; smaller warts on the exposed parts of the limbs; a string glandular fold from the posterior cormer of each upper eyelid, descending obliquely to the forelimb; large warts near the anai region; numerous warts varying in size on the posterior aspect of the thigh. Belly with numerous smooth warts,with smaller ones scattered on the inner and ventral sides of the arms. Two pairs of large glands on the thoracic region (fig.21,A); the chest glands, the unner pair,slightly longer than beoad, rounded anteriorly, the posterior margin squarish, with indentatins; the outer pair, the axillary glands, oval, the anterior, two-thirds of the inner margin in contact the posterior lateral margin of the chest gland; both pairs smooth and eithout black asperities or spines; light-colored nuptial pads developed on the inner dorsal sides of the first two fingers.
