Adult morhology Vomerine teeth in two small, round, distinct, well-separated patches between the choanae; tongue a little more than two-thirds the width of mouth opening, very broadly cordiform, slightly indented on its posterior border which is only narrowly free; snout short, bluntly rounded when seen from above, slanting forwards in profile, the upper jaw projecting slightly beyond the lower; nostrils more superior than lateral, projecting, their distance from end of snout about one-third that to eye, separated from each other by an interval a trifle less than their distance from eye. Canthus rostralis curving, fairly distinct because of the flat sloping loreal region, below which the upper lip bulges out, leaving a diagonal furrow from eye to nostril below the loreal region; diameter of eye equal to its distance from end of snout; interorbital diameter 1 1/4 times the width of the upper eyelid, greater than interval between the nostrils. Tympanum distinct, equal to one-half the diameter of eye, separated from eye by a distance equal to half its own diameter. Fingers quite long, webbed at the base, fourth much longer than second and reaching nearly to disk of third which covers one-half the tympanic area; a minute but sharp spine at base of first finger; toes one-half webbed, fifth slightly longer than third, disk of fourth covering about one-third the tympanum; a small inner but no outer metatarsal tubercle; a definite inner tarsal ridge; a similar ridge across heel but no true dermal appendage on heel. Body elongate, in postaxillary region narrower than greatest head width; when hind leg is adpressed, heel reaches to between eye and nostril; when hind limbs are laid along the sides, knee and elbow touch; when hind legs are bent at right angles to body, heels overlap. Skin of upper parts smooth; a slight glandular ridge beginning on canthus rostralis, continuing behind the eye over the tympanum and down the sides nearly to the groin; a transverse glandular line in front of anus; a very faint glandular line along outside of forearm and tibia; skin of throat and chest very coarsely granular, that of belly and lower femur heavily but more finely granular; no apparent skinfold across the chest. A heavy external vocal sac across entire throat appearing as )(-shaped skinfolds almost at the commissures of the lower jaws. Color in life. Variable. Some specimens On top, light saturated enamel green, uniform except for a wavy interrupted line which shines golden at night and is paler by day but always has a metallic sheen. It does not quite reach the groin and continues from the fold over the tympanum; lines similar to this found on forearm and on foreleg. This line is the only break in the uniform green dorsal ground. Tympanum light brown. Iris golden, broad. Pupil horizontally elongate. Edge of mouth with metallic sheen. Throat citrine with darker network. Abdomen and lower side of limbs adjacent to body white. Both abdomen and these parts with a fine lavender network. Outside of thigh spotted in weak orange and light brown spots. Some specimens became grayish tan where it was green; the metallic wavy line persisted. Sometimes darker, sometimes lighter, sometimes motherof-pearl, but is never silver. Underside granular with yellow pigment on the gula. Sometimes there is a little brown on the lower part of the wavy line, but mixed with it and not straight.
