452 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. 
V arvation:— The females and young males are very different from 
the adult males in being generally grayer and profusely dappled with 
light blue-gray. One specimen, an adult female (same data as above) 
is generally olivaceous gray above. Two indistinct brown bands run 
the length of the flanks. The sides and upper surface of the body, 
appendages and most of the tail is profusely spotted with light gray, 
while the under surface is bluish except for the gular folds which are 
suffused with black. A young specimen (same data as above) is 
identical with the female. Oddly enough the lateral bands are even 
less distinct than in the adult. 
Remarks:— The description was made of an adult male that meas- 
ured one hundred and thirty-five millimeters from snout to vent. 
This species is a noteworthy exception to the general rule that the 
young tend more to be distinctly striped than the adults. 
We have examined only the ten types of this species the data for 
which is given before the description. In this series of specimens 
there are young and adults of both sexes. 
Habitat:— Apparently confined to the island of Montserrat. The 
Ameiva from the neighboring island of Antigua is unknown, if one © 
still occurs there. : 
AMEIVA ATRATA Garman.
