 diameter equal to three-fourths its distance from end of snout; inter- 

 orbital diameter about two-thirds the width of upper eyelid, equal to 

 distance between nostrils. Tympaaum large, distinct, one-half the 

 width of eye, separated from eye by an interval equal to one-half its 

 own diameter. Fingers free, without perceptible lateral ridges, 

 fourth a little longer then second, reaching to base of penultimate

 when hind leg is adpressed, heel reaches between eye and nostril; 

 when limbs are laid along the sides, Imee and elbow touch; when hind 

 legs are bent at right angles to body, heels overlap. Skin of upper 

 parts smooth except for a few pustules posteriorly; a pair of narrow 

 glandular dorsolateral folds and two fainter folds near the middle of

 following the row of glands, bordered above and below by brown lines ; 

 a less apparent light line on center of posterior femur paralleling the 

 glandular white^line; a light brown stripe on anterior and posterior
