gradually diminishing in depth towards the angle of the mouth. The 

 lower labials are twelve in number, anteriorly more developed than 

 the upper ones, and likewise diminishing in size posteriorly : none of 

 them extending as far as the angle or the commissure of the mouth, 

 which, from beneath the pupil, is arched upwards, and bordered with 

 small scales, not distinguishable from those covering the rest of the 

 head. The symphyseal is much smaller than the rostral, and hardly 

 larger than the first lower labial. There is one pair of mental shields 

 of moderate development ; between each of which, and the labials, 

 may be seen four or five small plates, diminishing in size backwards. 

 The scales under the throat are reduced to minute granules. 



The eye is large, and the orbit subcircular, bordered by a double 

 row of small subconical scales. The auricular aperture is of moderate 

 development, and distant from the angle of the mouth about one 

 ocular diameter. 



The legs are stout and short, the extremities of the toes hardly 

 meeting one another when the posterior ones are bent forwards along 

 the side of the abdomen. The inner toe is clawless ; they are all 

 broad, subelliptical, bordered with a series of narrow and elongated 

 scales, minutely granular on their upper surface, and plated beneath, 

 each plate being gently undulated. 



The ground color above is blackish-brown, with cloudlike patches 

 of black and greenish-white ; the sides of the abdomen, legs, and tail 

 exhibit conspicuous white spots, and a few black dots. Beneath, the 

 hue is of a greyish-olive. The toes themselves appear to be entirely 

 olivaceous. The labial plates being yellowish-olive. 



The young are brown above, transversely and irregularly barred 

 with black ; beneath of a soiled white.
