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

 1902, 24, p. 183. 

 Habitat: — Probably widely distributed throughout Venezuela. 



Ameiva ameiva petersii (Cope). 



Ameiva pleurotaenia Peters, Monats. Berl. acad., 1871, p. 398, 652. 



Description.— Adult male; M. C. Z., 3023. Teffe, 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. 



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 w^iite line 

 bordered with black 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.
