The British Miiseutn possesses a single specimen of A. pmeiatm 
from Rio Janeiro, which shows tlie slight differences from A. nadcm 
indicated in the descriptions of Dumeril and Bibron, Of this latter 
Sf^eeies there are also four examples, all males, wiiile the other is a 
female. I cannot resist the conctuston indicated in the above revised 
synonymy, in which, of course, the older name of Daudin takes 
precedence,] 
The fine specimen in Mr. Buckley's collection which I formerly 
named A, nasicus (P. Z. S. 1880, p. 491) does not really belong to 
that species, only superficially resembling it, and is apparently an 
undescribed one, which I have pleasure in naming after my friend 
M. Boulenger;— 
18, Anolis boulengeri, sp. n, (Plate XXIV. fig, 1.) 
Uead elongate ; muzzle raised j prefrontal space concave ; anterior 
upper portions of head covered with rounded or polygonal scales, 
moderate-sized, slightly convex on the rauzztCj flat on the frontal 
region. Orbital semicircles of very large scales, separated on the 
vertex by the interorbitals, which have dwindled to one or two very 
Bmall scales in a single aeries, A central group of large supra- 
orbitals surrounded by small rounded or polygonal ones, A single 
long anterior supraocular continuous with the long canthnl acalfs. 
Occipital plate large, rounded, very little longer than wide, larger 
than the ear-opening. Six series of frenala. Seven snpralfibinls ; 
eight infralabials, with large scales in several rows beneath. Scales 
of the entire upper surface and sides nniform, minute, granular ; 
those of the ventral surface very small, rounded, and diijttnctty 
carinate. Toes with broad dilatations. Tail long. 
Bright green, with round pearl-like white spots in transverse rows 
on the back and sides. Lower parts yellowish.

From Caneloa, Tliis species shows a remarkable analogy to A, 
punciatm in the shape of the head, projiortiona of the body and 
coloration, the white spots being very similar. It is, distinguished, 
however, by the keeled ventral scales, those of A. punctatut being 
flat and smooth. A peculiarity which 1 have remarked in all the
