Snout turned upwards; rostral large, in contact with the anterior 
angle of the frontal; prefrontals trapezoid, broader than long, 
separated by the frontal; latter hexagonal, a little longer than 
broad, followed by a pair of smaller parietals which are broader 
than long; no occipitals; a supraocular, a little smaller than the 
ocular; two temporals, upper largest ; two upper labials, first twice 
as long as second. Mental very small, quadrangular, followed by a 
large chin-shield ; a pair of small lateral chin-shields on each side ; 
two lower labials, first much larger than second. Two hundred 
and seventy-eight annuli on the body and seventeen on the tail ; 
nine or ten large, elongate, narrow pectoral shields on a transverse

Closely allied to the preceding, but differing in the presence of a 
pair of large occipitals and the different pectoral scutellation, which 
consists of numerous, mostly small, shields, of which the median pair 
alone is much elongate. Frontal octagonal, forming an obtuse angle 
anteriorly and posteriorly ; occipitals twice as broad as long; three 
upper labials, the first largest, the third very small. Two hundred 
and thirty-one annuli on the body and thirteen on the tail; an 
annulus of the body contains thirty-two dorsal and twenty-four 
ventral segments. Six anal segments. 
Length to vent 312 millim.; tail 18 millim.

Preemaxillary teeth 3; maxillaries 4—4; mandibulars 5—5, 
Snout more depressed than in L. microcephalum, with sharper rostral 
edge ; rostral large, widely separated from the ocular; frontal much 
longer than broad, narrowed, and in contact with the rostral ante-
