Sphaerodactylus elegantulus Barbour, Proc. Biol. soe. Wash., 1917, 30, p. 163. 
Type-locality:— Antigua. 
Type:— M. C. Z. 12,084, a very young and therefore misleading specimen. 
Dr. D. W. Griswold. 
Distribution:— Antigua. 
Diagnosis:— Medium sized, with rather large keeled, imbricate dorsals of 
which twelve or thirteen equal the distance from tip of snout to centre of eye; a 
middorsal zone of scales of decidedly lesser size; only three large supralabials 
and the anterior pair of these bordered by only five large scales in the basal 
loreal row. 
Description of type:— Snout rather short but acute, the distance from tip of 
snout to eye being about equal to distance of eye from ear-opening, and more 
than twice the diameter of the eye, which is rather small; rostral rather large 
with a median cleft behind; nostril between rostral, first supralabial, one or two 
small postnasals and a decidedly enlarged supranasal which is separated from its 
fellow on the opposite side by a single scale, slightly smaller than one of the 
supranasals; these three scales border the rostral posteriorly ; three large supra- 
labials to below the centre of the eye; above the centre of the eye the usual spime- 
like scale is present; top of head covered with tiny granules increasing in size 
upon the neck; back covered with larger keeled slightly imbricating scales and 
with a very narrow ill-defined median dorsal zone of scales of much reduced size, 
these characters evident in adult; in the young type 13 scales or in the adults 9 
scales, counting in a straight line on the middorsal region are equal to the distance 
from the tip of the snout to the middle of the eye; scales of chest and belly round, 
smooth, and slightly imbricating, scales of throat granular, of limbs granular 
in young type, swollen, keeled, but nonimbricating, in adults; scales of tail in 
whorls, squarish, flat, not imbricating in young type, slightly imbricating in 
adult, a subcaudal series of enlarged scales, mental large, as large as rostral, 
followed by a very large, a medium sized and a very small infralabial; two small 
squarish postmentals slightly enlarged. 
Colour:— Rich mahogany-brown, the head lighter than the body; very 
narrow pure white cross-bands arranged as follows, one on nape, one just ante- 
rior to and another just behind fore limbs, two across midbody, one just before
