SYSTEMATIC ACCOUNT OF THE SPECIES. 243 
the eye to the ear-opening, not quite twice the diameter of the eye; rostral rather 
large with long median cleft behind; nostril between rostral, first supralabial, a 
single rather large postnasal and a larger supranasal which is separated from its 
fellow of the other side by a single small scale these three bordering the rostral 
above; three large supralabials to the centre of the eye; head above and on the 
sides covered with small, rounded, granular or tubercular scales; those on back 
small, keeled, very slightly imbricate, fourteen equivalent to the distance from 
tip of snout to centre of eye; mental large, longer than rostral; one very large, 
one medium sized and one small infralabial to below the centre of the eye; two 
small chin-shields behind mental followed by a series of five flat smaller scales, 
scales of throat and lower neck uniform in size, flat and polygonal; on chest and 
belly larger, flat and slightly imbricate. Scales of limbs small, elongate, imbri- 
cate and keeled; of tail above whorls of small pointed imbricate slightly keeled 
or flat scales, below with a median series of large hexagonal plates with several 
lateral series of smaller flat scales. 
Colour:— Almost uniform brown above with very faintly indicated chevron 
shaped lighter markings on hind neck and sacral regions. 
Remarks:— This species is evidently one of the medium sized forms, being 
considerably larger than torrei from Cuba, of course far larger than elegans, and 
not reaching to anything like the size of copet from Haiti, anthracinus Andros or 
richardsonit from Jamaica which are the largest species in the genus. In no one 
of the three examples before me is the tail perfect, but the length of the largest 
specimen (PARATYPE Univ. Mich. Mus.) from snout to vent is 30 mm. The 
type is not quite so large, but all the specimens are evidently adult.

Type-locality:— Port Antonio, Jamaica. 
Types:— Not known. 
Distribution:— Jamaica. A woodland species which is found under leaves 
- and decaying trash from sea-level to the summits of the Blue Mountains. It is 
very rare in the dry, semiarid regions such as the plains near Kingston and 
Spanishtown.
