Head 3| to 4 times in length to vent, sometimes as deep as broad, 

 sometimes a little broader, the cheeks often swollen in the males, 

 Pileus usually twice as long as broad. The hind limb reaches the 

 wrist or the elbow, rarely the axil * or just overlaps the fore limb t ; 

 foot as long as or slightly longer or slightly shorter than the head. 



Lepidosis as in the typical form, but suture between the praef rentals 

 sometimes longer, frontal sometimes nearly twice as long as broad, 

 interparietal often broader (2 to 3 times as long as broad), first supra- 

 ocular often extensively in contact with the fi-ontal, the fourth some- 

 times separated from the anterior upper temporal + ; 2 to 6 small 

 scales between the supraoculars and the superciliaries, of which there 

 may be 7 ; anterior loreal sometimes more than half as long as 

 second ; tympanic sometimes very small, rarely absent. 25 to 33 

 gular scales in a longitudinal series ; collar composed of 7 to 14 plates. 

 44 to 60 scales across the middle of the body. Ventral plates in 27 to 

 34 transverse series. A large praeaual bordered by 4 or 6 smaller 

 shields, or 2 large praeanals, one in front of the other, or 3 

 forming a triangle bordered by a semicircle of small plates. 11 to 20 

 femoral pores on each side. 20 to 26 lamellar scales under the fourth 

 toe. 



* Male and young from Bulawayo. 



t Female from Lake Nyassa. 



J Males from Vredefort Road and Eustenburg, females from Lydenburg and 

 Kimberley. The upper temporal is then entirely on the temple. Bedriaga 

 observes, a propos of his L. cameranoi, that the upper temporals are on the 

 upper surface, forming part of the pileus, in the South African species (my 

 Nucras). The series of specimens here referred to N. intertexta shows this 

 character to be by no means a constant one, as these shields may be lateral 

 and perpendicular to the parietals. There is thus in Nucras the same amount 

 of variation with respect to this feature as in L. muralis, in which Mehely has 

 used it for the distinction of his Archaeolacertae and Neolacertae.
