and fourth small, the three anterior in contact with the frontal, the second 
and third equal ; 6 superciliaries, separated from the supraoculars by a 
complete series of granules. Lower eyelid opaque, with vertically enlarged 
scales in the middle. Eostral not entering the nostril ; 2 superposed post- 
nasals ; anterior loreal ^ the length of the second ; 5 upper labials anterior 
to the subocular, which is narrower beneath than above ; temporal scales 
granular ; a very narrow tympanic shield. 
Four pairs of chin- shields, and a very small fifth, first three in contact 
in the middle ; 25 gular scales between the symphysis of the chin-shields 
and the median collar-plate, increasing in size and imbricate towards the 
collar ; no gular fold ; collar with strongly serrated edge, composed of 10 
plates. 
Scales strongly keeled, granular on the nape, rhombic and feebly 
imbricate on the body ; the keels distinct on the lateral scales down to the 
ventrals ; 42 scales across the middle of the body, 32 in a transverse series 
between the hind limbs. Ventral plates in 8 longitudinal series, the outer 
plate small, and 26 transverse series. Preanal plates small, forming pairs 
in the middle. 
A series of 7 large transverse plates under the forearm. Scales on 
upper surface of tibia keeled, much smaller than dorsals. 13-14 femoral

This species is very closely allied to L. johnstonii, Blgr., from Nyassaland, 
altitude 2000 metres, which differs chiefly in the narrower head, the longer 
parietal shields with concave outer border, and more numerous scales (50 to 
52 across middle of body). L. johnstonii wsis the southernmost species of 
the genus, the range of which extends - to the Soudan, Arabia, Asia Minor, 
and Mesopotamia.
