scales very small, longer than broad, smooth or feebly keeled; 62 to 

 84 plates and scales across the middle of the body. " Ventral' plates 

 quadrangular, the transverse series with rectilinear border in 

 6 longitudinal and 25 to 31 transverse series. A moderatelv I'aro-e 

 preanal plate, bordered by a semicircle of smaller plates, the mediln 

 of which is sometimes transversely enlarged. 



A series of transversely enlarged plates on tlie upper surface of 

 the fore limb ; upper surface of hind limb with small granular scales. 

 16 to 24 femoral pores on each side, the two series sometimes meetiuo- 

 in the middle. 16 to 20 lamella? under the fourth toe. 



Nearly the whole of the tail occupied bv a double series of laro-e 

 transverse plates, above and below, usually longer and shorter 

 alternately, the lateral edge with large triangular curved scales 

 forming a strong serration ; on the basal part of the tail, a series 

 of small scales intervenes between the large plate and the scales 

 forming the lateral serration.* 



Black above, the head with three yellowish longitudinal streaks, 

 the median extending from the rostral to the occipital or a little 

 prolonged on the nape and expanded on the frontal, the lateral 

 narrower, originating on the first supraocular and extending on the 

 parietal, converging towards its fellow to approximate it on the nape 

 and continued on the body ; 6 yellowish or bluish-green streaks on the 

 body, the median pair Ijroadest, nearly as broad as or much narrower 

 than the space between them, and uniting on the tail ; the two other 

 streaks on each side starting from behind the eye and from the upper 

 lip respectively, then sometimes extending on the fore limb. In the 

 specimen from Usambara (subsp. Ixvis, Werner), and in the one 

 from Zomba, there is only one light lateral streak, proceeding from 

 the upper lip, quite as broad as the dorsal. Hind limbs greenish 

 above, sometimes spotted with black, and with black base iu front. 

 Tail blue above and l)eueatli, with black bars or cross-lines, above 

 with two black longitudinal streaks. Lower parts greenish blue, blue,
