W. Robinson, and recorded by Dr. Stejneger in Proc. U. S. N. M.,

AMEIVA AMEIVA PETERSII (Cope). 
Ameiva pleurotaenia Peters, Monats. Berl. acad., 1871, p. 398, 652. 
Description:— Adult male; M. C. Z., 3023. Teffé, Brazil; 1865; 
L. Agassiz. 
Similar to Ameiva a. ameiva from which it may be distinguished by the 
following characters:— Gulars forming a distinct group of consider- 
ably enlarged scales in the middle of a band of others slightly enlarged; 
three rows of brachials instead of two, the scales of which are larger 
than those of Ameiva ameiva; dorsal surface pale-olive tinged with 
bluish; upper and lateral surfaces of the body sprinkled with black, 
the spots unlike Ameiva ameiva, not being confluent; under part of 
neck and chin similarly spotted; on each flank a series.of whitish spots 
in vertical rows, the spots more or less surrounded with black; below 
the series of white spots and on the outer ventrals numerous irregular 
black blotches; on each side of the body a trace of two broad lateral 
bands of brown. e 
Variation:— A female (same data as above) differs from the male — 
in that the dark spots on the back and head are nearly absent. The — 
lateral dark stripes are more distinct than those of the male. On the 
lower border of these stripes there is on each side a narrow white line © 
bordered with blaek extending the length of the body. A young male 
M.C. Z. 3432 (same data as above) is indistinguishable from the young ~ 
of Ameiva ameiva in color except that the general tonality is darker. 
Remarks:— The description was made of an adult male that meas- 
ured one hundred and sixty-two millimeters from snout to vent. | 
Habitat:— Found along the upper Amazon, probably from the 
Madeira River westward. a
