 the diameter of the orbit ; eye large ; ear-opening small, roundish. 

 Body and limbs moderate. Digits much depressed, with large 

 transverse lamellae inferiorly, about seven under the fourth toe, the 

 middle ones chevron- shaped, the distal one heart-shaped, the basal 

 ones divided into two rounded plates ; the plates under the apex of 

 the digit large, together cordiform. Upper surfaces covered with 

 minute granules, intermixed with few irregularly scattered conical 

 spine-like tubercles, llostral pentagonal, completely divided medi- 

 ally ; nostril pierced between the rostral, the first labial, and three 

 or four nasals ; thirteen to fifteen upper and as many lower 

 labials ; mental small, trapezoid, not larger than the adjacent 

 labials ; no chin-shields. Lower surfaces covered with small juxta- 

 posed granules, largest on the belly. Males with a doubly arched 

 series of eleven to fourteen prseanal pores, and three or four large 

 conical tubercles on each side of the base of tail. Tail short, sub- 

 cylindrical, prehensile, covered with small granules ; on each side of 

 its upper surface a series of long black spines. Upper surfaces 

 olive-grey, speckled with black ; the spinose tubercles black ; some- 

 times a rather indistinct broad zigzag band along the back ; lower
