Head once and one third as long as broad. Nasals scarcely- 

 swollen, in contact with each other, pierced in the middle ; 

 fronto- nasal pentagonal, longer than broad, separating the 

 prefrontals, and forming a suture with the frontal ; frontal 

 heptagonal ; interparietal enclosed between the four parietals ; 

 temporals in three longitudinal rows ; no spines ; four supra- 

 oculars ; three supraciliaries ; a loreal, a prasocular, and two 

 suboculars ; six lower labials and five large chin-shields on 

 each side ; gular scales small, obtusely keeled, gradually in- 

 creasing in size posteriorly. Dorsal scales large, quadrangular, 

 rough, strongly keeled, in ten or twelve longitudinal and 

 twenty-one transverse series (from occiput to base of tail) ; 

 sides of neck with small keeled rhomboidal scales ; lateral 

 scales much smaller than dorsals, rhomboidal, strongly keeled, 

 separated from one another by granules. Ventrals smooth, in 

 twelve or fourteen longitudinal and twenty-six transverse 

 series. Two enlarged posterior praeanal scales. Upper sur- 

 face of limbs with imbricate strongly keeled scales. Six 

 femoral pores on each side. Tail with whorls of large, rugose, 

 strongly keeled, spinose scales ; the keels strong even on the

A single male specimen was obtained by Mr. C. R. Jones 

 in the Murchison Range, Transvaal, and presented by him to 

 the British Museum. Curiously another new species was 

 discovered in the Transvaal only four years ago, and described 

 by Dr. Reichenow as Z. vittifer *.
