 developed, smaller than the inner metatarsal tubercle; a rather 

 weak tarsal ridge, which fades out halfway to heel. Body rather 

 elongate, in postaxillary region narrower than greatest width of 

 head. When hind leg is adpressed, heel reaches far beyond tip of

 considerably; when hind legs are bent at right angles to body, heels 

 overlap greatly. Skin of upper parts minutely granular; a row of small 

 glands between the eyes, and two other rows of glands from above 

 the tympanum diagonally to center of back; a heavy glandular ridge 

 from posterior corner of eye, above and behind tympanum, ending 

 at shoulder. Venter smooth, except for a few granulations around 

 anus. Ventral disk rather indistinct. No external vocal sac.

 hour-glass-shaped longitudinal sepia marking extending from inter-

 covering tubercles above the shoulder (on some specimens, only the 

 upper one is distinct) ; a heavy black line bordering the supratympanic 

 glandular fold; top of femur with seven or eight alternately narrower 

 and wider dark crossbars, the wider ones continuing less distinctly 

 on upper tibia and foot; similar but fewer crossbars on forearm; 

 venter cream color, with numerous sepia spots on chin and throat; two 

 larger dark spots on each side of breast below shoulder, and several 

 widely scattered dots on anterior half of belly; side of body cinnamon,

 some very small, indistinct, darker spots below anus and along latero- 

 ventral border; sometimes a dark distinct posterior anal patch; sides 

 of head ecru drab, the loreal region and tympanum dark cinnamon;
