Snout rather short and blunt, the distance from the tip to the eye being less 
than that of the eye from the ear; rostral moderate with a very long median 
cleft behind; nostral between rostral, first supralabial, one postnasal and a very 
small supranasal, which is separated from its fellow on the opposite side by four 
small scales, these six scales bordering the rostral posteriorly; three large and 
one small supralabial to below the centre of the eye; a small spine on the super- 
ciliary margin above the centre of the eye; head above and on sides covered with 
very minute granules, but slightly enlarged upon the snout; scales of back small, 
somewhat elongate, keeled and very slightly imbricate about thirteen in a straight 
series equalling the distance of tip of snout from centre of eye; mental moderate, 
as large as rostral; one very large lower labial followed by a medium and a small 
infralabial to below the centre of the eye; two small squarish chin-shields behind 
1 Boulenger (Cat. lizards Brit. mus., 1885, 1, p. 220) states that the type is without data. 
2 According to Gray this specimen belonged to Leadbeater. Boulenger, however, makes no mention 
of this fact. Until the type can be reéxamined it is uncertain that these Cuban specimens are correctly 
assigned.
