SYSTEMATIC ACCOUNT OF THE SPECIES. 249 
Unfortunately this description does not allow us even to surmise what may 
be the affinities of buergeri but if one may hazard a guess it is far from improbable 
that the difference from molei which are assumed may be due to the difference in 
the methods of observing by Boettger and Werner; for I strongly suspect that 
both had the same species.

Type-locality:— Jamaica. ‘‘Common in houses, in corners, and crevices.” 
Types:— British Museum. A series of specimens. P. H. Gosse. 
Distribution:— Found very abundantly throughout the lowland regions of 
Jamaica. It occurs at Mandeville but was not found in the highlands of eastern 
Jamaica by the writer in 1909. It is very abundant in houses as well as in 
suitable situations about cultivated and wild areas. 
Diagnosis:— Medium size, with small, keeled, slightly imbricate scales, 
about ten or eleven equalling distance from tip of snout to centre of eye; about 
fourteen small scales between the orbits; a colouration of many distinct minute 
ocellated spots. 
Description:— M. C. Z. 13,593. Jamaica: Constant Springs near Kingston, 
1909. One ofa large series (M. C. Z. 7,345). Thomas Barbour. 
Snout rounded, short; eye slightly nearer tip of snout than ear; rostral 
small with median groove, and a crescentic groove on each half of the rostral as 
well; nostril between rostral, a large supranasal and three small scales which 
almost always occlude it from the first supralabial; suture of fourth and fifth 
supralabial below the centre of the eye; superciliary spine present; head above 
and on sides covered with small homogeneous granules, distinctly enlarged on 
snout; dorsals small, keeled, slightly imbricating; about eleven equal the dis- 
tance from tip of snout to centre of eye; mental larger than rostral; followed by 
a few enlarged postmentals; gular scales small flat, roundish; ventrals over- 
lapping, larger than dorsals, perfectly smooth; limbs partly covered with small 
granules and partly with small, round, imbricate, smooth scales; scales of tail 
rounded, smooth, strongly imbricate, not forming whorls; large plates present 
on lower surface. 
Colour:— Reddish or brownish with fine light spots on back and sides; on
