BARBOUR AND NOBLE: LIZARDS OF THE GENUS AMEIVA. 4031 
very slightly larger ones extending across the middle; on the portion 
between the two throat folds several rows of large hexagonal scales; 
under side of the body with ten longitudinal and thirty-five transverse 
rows of plates; preanal plates in a subtriangular group of large scales 
irregularly arranged, but having four scales on the base and being 
three scales in height; on the lower arm a double row of small ante- 
brachials and a single row of large ones, all gradually diminishing in 
size toward the elbow joint; on the upper arm a single row of brachials 
almost continuous with the antebrachials; on the posterior side near 
the elbow a single row uf enlarged postbrachials; under side of thigh 
covered with six or seven series of hexagonal plates of which the outer 
series is considerably larger than the others; fourteen femoral pores; 
on the under side of the tibia two rows of plates, those of the outer 
being enormously enlarged; upper side of the wrist with a regular 
series of transverse plates corresponding to the inner and outer meta- 
tarsals; fifth toe extending approximately as far as the inner; tail 
covered with straight scales with keels; about thirty-five scales in the 
fifteenth ring from the base. 
Coloration: — Ground color of dorsal surface olive-brown with 
traces of blue-gray posteriorly; on each side a rather wide black 
stripe becoming narrow anteriorly, extending posteriorly half the 
length of the tail; the black stripe on each side set off by two marginal 
stripes of pale blue; lower flanks and ventral surface turquoise-blue 
of low intensity; most of the throat, chest, and abdomen washed with 
black, darkest in the gular fold region; chin-shields, palms, lower 
surfaces of feet, lower side of tail washed with yellow. 
Variation: — The female and young are very similar to the adult 
males except that the colors are brighter and the pattern more dis- 
tinct. The pale margin of the lateral black bands become whitish 
anteriorly. There is often added a median stripe of pale blue-gray 
running the length of the back. Young specimens sometimes have no 
black throat, then the whole ventral surface is pale blue. 
Remarks:— The description was made of an adult male that meas- 
ured one hundred and eleven millimeters from snout to vent. 
Habitat:— Common throughout its limited range which includes 
the Bahaman Islands of New Providence, Eleuthera, and Andros. It 
has been reported from Great Abaco but was not found there by 
the Harvard Bahama Expedition of 1904.
