Anisolepis iheringii, Bouleng. I. c. p. 86. 



Head small, body elongate. Nostril lateral, near the end of the 

 snout; ear-opening moderately large, oval. Upper head-scales 

 small and smooth, smallest on the supraocular region ; occipital 

 enlarged, suboval, about as large as the tympanum ; upper labials 

 eight, very low. Gular scales granular and keeled medially, larger 

 and smooth anteriorly, gradually larger, rhomboidal, imbricate, and 

 strongly keeled towards the gular fold, which is strong and straight. 

 Median dorsal scales larger, irregular, imbricate, strongly keeled, 

 the largest forming one or two indistinct longitudinal series on each 

 side of the vertebral line ; dorso-lateral scales very small, granular, 

 keeled, unequal, intermixed with irregularly scattered enlarged 

 scales. Ventral scales much larger than dorsals, equal, rhomboidal, 

 imbricate, strongly keeled, the keels forming straight longitudinal 

 series. The adpressed hind limb reaches the axilla or the shoulder. 

 Tail more than twice as long as head and body, covered with equal 

 keeled scales. Olive-brown above, with a series of triangular dark 

 brown spots on each side of the vertebral line, forming a zigzag 

 band ; this is bordered externally with yellowish or reddish ; the 

 triangular spots may send forth narrow dark brown lines obliquely 

 directed posteriorly down the sides ; lower surfaces yellowish or 

 coppery, the throat with a few blackish dots or longitudinal lines ; 

 tail above with a series of rhomboidal, dark, light-edged spots.
