Head small, considerably broader than deep, li to If times as long 

 broad, its length 4 to 4| times in length to vent; snout obtuse. 

 Pileus 2 to 2i times as long as broad. Body feebly depressed. Hind 

 limb reaching the elbow, the axil, or the shoulder ; foot considerably 

 longer than the head ; digits slender, feebly compressed. Tail flattened 

 and widened at the base in males, nearly 2 to 2f times as long as head 

 and body. 



Nasals forming a short suture behind the rostral; frontonasal 

 broader than long, broader than the internarial space ; praefrontals 

 forming a short suture ; frontal as long as or a little longer than its 

 distance from the end of the snout, 1^ to 2 times as long as broad, 

 narrower, behind , than the supraoculars ; f rontoparietals much shorter 

 than the frontal or than their distance from the posterior border of the 

 pileus ; parietals 1^ to 1J times as long as broad, outer border some- 

 times emarginate for the accommodation of the anterior upper 

 temporal; interparietal narrow, 2.! to 4 times as lo l>n>ad; 



occipital very short, sometimes broader than the int.T] ;< i -id;tl. Four 

 supraoculars, first and fourth small, and sometimes divided into two, 

 first extensively in contact with the frontal ; 7 or 8 superciliaries : 

 2 to 7 small scales between the supraoculars and the superciliaries. 

 Two superposed postnasals, rarely one * ; anterior loreal i to f times 

 as long as second ; 4 upper labials anterior to the subocular, which 

 is a little narrower beneath than above ; an elongate anterior upper 

 temporal, often in contact with the fourth supraocular f, followed by 

 1 or 2 smaller shields ; temple covered with small hexagonal or gran- 

 ular scales, which are about as large as the dorsals or smaller ;. tym- 

 panic shield roundish, often small or absent. 



Parietal foramen usually absent. Pterygoid teeth present. 



Grular scales small, juxtaposed, increasing in si/e and imbricate 



* Types of L. taeniolata. Also in a young from Clamvilliam which, in its 

 marking's agrees with the 



f Not in contact in five S| 3 : one of the types of L. taeniolata, two of 



the types of L. livida, male from Deelfontein, and female from Little Namaqua-
