once and a half in the distance between axilla and groin. Snout 
short, rounded; no canthus rostralis. Lower eyelid scaly. Supra- 
nasals present, in contact behind the rostral; frontonasal much 
broader than long, largely in contact with the frontal; prefrontals 
small ; frontal about as long as frontoparietals and parictals together, 
in contact with the first and second, or first, second, and third 
supraoculars ; five supraoculars, fifth very small; eight or nine 
supraciliaries, first and last largest; frontoparietals and interparietal 
distinct, subequal, or interparietal smallest; parietals not or but 
very slightly in contact behind the interparietal; no nuchals; fifth 
and sixth labials below the eye, fifth largest. Ear-opening mode- 
rately large, oval, smaller than the eye-opening, without lobules. 
32 to 36 scales round the middle of the body, subequal; dorsals 
strongly, laterals feebly tri- or quinquecarinate. Praanals not en- 
larged. The adpressed limbs meet or fail to meet. Digits short, 
compressed ; fourth tve a little longer than third; subdigital lamellae 
feebly unicarinate, 14 to 18 under the fourth toe. Tail thick, 
little longer than head and body. Brownish above, the dorsal

Allied to L. fernandi. Supranasal imperfectly separated from 
the nasal, forming a suture with its fellow behind the rostral; 
frontonasal much broader than long, in contact with the frontal, 
which is long ; four supraoculars ; six or seven supraciliaries ; fronto- 
parietals and interparietal distinct ; fifth upper labial largest, sepa- 
rated from the orbit by a series of small scales. ar-opening small, 
round, with a triangular projecting scale in front. 28 scales round 
the body; dorsals sharply tricarinate, laterals almost smooth. The 
hind limb measures hardly more than three fifths the distance 
between axilla and groin. Yellowish grey above, irregularly dotted
