Synopsis of the Species. 



A. Nostril between 3 or 4 (rarely 2) shields, the rostral not entering its border j 



subdigital lamellse 16 to 2'S ; dorsal scales elliptic, rhombic or hexagonal, 

 strongly keeled ; '62 to 52 scales across the middle of the Vjody ; ventral 

 plates in 6 or 8 longitudinal series ; tail never twice the length of head 

 and body. 



Granules between the supraoculars and the superciliaries 

 usually absent ; iisually two large vipper temporals ; fronto- 

 nasal rarely broader than internarial space, usually between 

 6 shields; foot not longer than head . . .1. L. anilis, L., p. 39. 



A series of granules between the supraoculars and the super- 

 ciliaries (rarely reduced to 2 or 3) ; a single large upper 

 temporal ; frontonasal broader than the internarial space, 

 between 8 shields ; foot longer than head . 2. L. parva, Blgr., p. (50. 



B. Nostril between 5 or 6 (rarely 4) shields, the rostral nearly always entering 



its border; subdigital lamellse 21 to 31; iisually two large upper tem- 

 porals, the first in contact with the fourth supraocular ; tail 1^ to 21 

 times the length of head and body. 



Dorsal scales hexagonal or rhombic, rarely oval or roundish, 

 strongly keeled ; 38 to 58 scales across middle of body ; 

 ventral plates in G or 8 longitudinal series . 3. L. viridis, Laur., p. 64. 



Dorsal scales rhombic and subimbricate, strongly keeled, much 

 larger than the laterals ; 34 to 37 scales across middle of 

 body ; ventral plates in 10 longitudinal series. 



4. L. princeps, Blanf., p. 95. 



Dorsal scales granular, smooth or feebly keeled ; 63 to 100 scales 

 across middle of body ; ventral plates in 6 to 10 longitudinal 

 series . . . . . . 5. L. ocellata, Daud., p. 97-
