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 iufralabial 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 pomted 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 fighter 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 coiu:se far larger than elegans, and 

 not reaching to anything like the size of copei from Haiti, anthracinus Andros or 

 richardsonii 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.

 and decaying trash from sea-level to the summits of the Blue Mountains. It is

 Spanishtown.
