BARBOUR AND NOBLE: LIZARDS OF THE GENUS AMEIVA. 435 
W. M. Mann) shows the extreme of variation in the juvenile stages. 
The whole dorsal and lateral surfaces are jet black. Eleven, narrow 
whitish or milky stripes run longitudinally on the back and sides, the 
median one starting just behind the shoulders, the two adjacent ones 
coming to an apex about mid-way between the shoulders. The 
remaining eight stripes are nearly parallel, four arising on each side 
from the supraoculars, the supraciliaries, the upper and lower corners 
of the eye, respectively. The ventral surface is pale straw-color, 
suffused with deep blue on the tail. A slight wash of smoky covers 
the abdomen. The dorsal surface of the legs are spotted with white. 
Remarks:— The specimen from which the description was taken 
was an adult male that measured eighty-six millimeters from snout 
to vent. 
A careful examination of a series of twelve specimens of this species 
makes it clear that A. taeniura is the adult of A. lineolata. The 
specimens have a wide range of variation both in color and scutation. 
According to Cope (Proc. Acad. nat. sci. Phila., 1862, p. 64) the dis- 
tinguishing characters of A. taeniwra are mainly of color and tail 
scutation. One, however, of the specimens before us has the typical 
nine white bands, and keelless caudal plates of A. lineolata. Another 
specimen shows the extreme variation in this direction by having 
eleven dorsal bands and keelless caudal scales. Representing the 
other extreme are six specimens having the characteristic lateral bands 
and keeled scales of the tail of A. taencuwra. The remaining individuals 
have the coloration of A. lineolata but the keeled caudal scales of 
A. taeniura. These characters grade into one another and all the 
intermediate steps are present. Garman (Bull. Essex. inst., 1887, 19, 
p. 11) noticed the variation in the tail scutation, but pointed out 
the larger preanals, and the smaller mesotychium scales as character- 
izing A. taeniura. The larger series of specimens shows that these 
characters are not at all constant, and among the specimens there 
are many variations. 
Dumeril et Bibron (Erpet gen., 1839, 5, p. 119) in describing A. 
lineolata possessed but a single young specimen as shown by their 
measurements and by Bocourt’s figures of the type (Miss. sci. Mex. 
Rept., pl. xxa, fig. 5). In our specimens, also, it is always the smaller 
individuals that have the typical A. lineolata characters. 
Habitat:— Confined to Haiti where it is widely spread throughout 
both the republics.
