same transverse line as the other three; nine supraciliaries; four 
supraoculars, first separated from the loreal; three posterior supra- 
_ oculars separated from the supraciliaries by two or three rows of 
granules becoming fused into a single row anteriorly; last supraocular 
separated from the outer occipitals by three or four rows of granules; 
six supralabials; six and seven infralabials; between the infralabials 
and chin-shields a wedge of one to three rows of granules and scales 
extending anteriorly to the first chin-shield; chin and throat covered 
with minute granules a scarcely differentiated band of larger ones 
extending across the throat of which the median group of scutes’ and 
two groups anterior to it and on either side of it are composed of the 
largest granules; on the area between the two throat folds a transverse 
series of scales, about a dozen of the median scales, in a group, some- 
what enlarged; under side of the body with eighteen longitudinal and 
thirty-eight transverse rows of plates; preanal plates small, almost 
granular, in a transverse row of seven or eight scales and in a median 
row of two or three; on the lower arm three short rows of scales, the 
outer scales being much divided, all of the scales decrease rapidly in 
size from the mid-region to the elbow; on the upper arm a series of 
oblique rows each formed of four scales; on the posterior side near the 
elbow joint a small group of postbrachials scarcely differentiated in 
size from the granules of the arm; under side of thighs covered with 
seven or eight rows distally, with twenty-five or more proximately; 
thirty-one femoral pores; on the under side of the tibia five rows of 
scales, the two proximal ones of the outer row considerably larger 
than the others, the second the larger of the two; upper side of the 
wrist with a regular series of plates covering the outer edge only; 
outer toe extending about as far as the inner; tail covered with straight, 
keeled scales; about forty scales in the fifteenth ring from the base. 
Coloration: — Dorsal surface ashy gray, more bluish on the flanks, 
slightly more olivaceous on the head and tail; a trace of three indis- 
tinct stripes of a slightly darker tone of gray running the length of the 
body along the back; a suggestion of another dark stripe on each side; 
in places all five of these bands are indistinguishable from the ground 
tone; ventral surface straw-color or milky encroached upon laterally — 
by the blue of flanks and of the side of head. 
Variation: — Neither of the two females before us show any varia- 
tion of color from that of the adult male described. In this respect 
this species is rather peculiar. 
Remarks:— The description was made of an adult that measured 
one hundred and fifty millimeters from snout to vent. 
Three adult specimens, 1c and 2 9 9 of this species were exam- 
ined. Their numbers are M. C. Z. 10575-10577. 
Habitat:— Apparently confined to a small low island, known locally —
