concave and but slightly oblique, the upper lip not flaring out strongly 

 below it. Eye moderate, not particularly prominent, its diameter 

 equal to its distance from nostril; interorbital distance about twice 

 the width of upper eyelid, which is slightly greater than distance 

 between nostrils. Tympanum very distinct, about three-fifths the 

 diameter of eye, separated from eye by a distance nearly equal to 

 two-thirds its own diameter. Fingers with a trace of web at base, 

 fourth finger considerably longer than second, reaching to middle 

 of disk of third, which slightly more than covers the tympanic area; 

 no projecting rudiment of a pollex. Toes about one-half webbed, the 

 web on fourth toe reaching the proximal one-third of the antepenulti- 

 mate phalanx, fifth toe about a disk longer than third, disk of fourth 

 just covering the tympanic area; a distinct oval inner and a smaller 

 but equally distinct rounded outer metatarsal tubercle; no tarsal 

 ridge; no dermal appendage on heel. Body not elongate, in postaxillary 

 region a little broader than greatest width of head; when hind leg is 

 adpressed, heel reaches anterior margin of eye; when limbs are laid 

 along the side, knee and elbow meet; when hind legs are bent at right 

 angles to body, heels overlap greatly. No patagium. Skin of upper 

 parts smooth, a rather narrow, glandular bony ridge passes above
