Description.—A larger and stouter snake than L. zonata. 
Top of head slightly flattened posteriorly, curving down- 
ward to the broad rounded snout. Temporal regions rarely 
if ever swollen. Rostral plate large, little broader than high, 
hollowed below, and bounded behind by internasal, anterior 
nasal, and first labial plates. Plates on top of head are a 
pair of internasals, a pair of prefrontals, a short, broad, 
irregularly wedge-shaped frontal, supraocular of each side, 
and a pair of large parietals. Anterior and posterior nasals 
distinct. A small loreal present, but very rarely united with 
posterior nasal. One preocular and two (rarely one) post- 
oculars. Temporals normally two followed by three, but 
may be 2+2, 2+4, or 3+4. Seven or rarely eight superior 
and nine, rarely eight or 10, inferior labials, fifth and sixth 
superior and fifth or fourth inferior largest, third and fourth 
superior reaching eye, first pair of inferior meeting on 
median line. Genials in two pairs, anterior much larger 
than posterior. Scales smooth, thin, imbricate, in 23 or 
rarely 25 rows. Anal plate not divided. Gastrosteges vary- 
ing in number from 206 to 254. Urosteges in two series 
of from 41 to 62, a few of the first sometimes undivided. 
The snout and sides of the head are yellow or white,
