BARBOUR AND NOBLE: LIZARDS OF THE GENUS AMEIVA. 433 



brachials; on the posterior side near the elbow a small group of en- 

 larged postbrachials; under side of thighs covered with six or seven 

 series of hexagonal plates of which the outer series is somewhat 

 larger than the others; seventeen and eighteen femoral pores; on the 

 under side of the tibia three rows of plates, distally four rows, the third 

 and fourth plate of the outer row considerably enlarged; upper side 

 of the wrist with a regular series of transverse plates covering only the 

 outer region; outer toe extending a little further than the inner; 

 tail covered with straight scales with keels; about forty-five scales in 

 the fifteenth ring from the base. 



Coloration: — Ground color of dorsal surface blue-gray; pattern 

 of coloration like A. vitti punctata but the seven dorsal white lines 

 running the length of the back broken up into a series of indistinct 

 more or less confluent spots; on each side a rather indistinct black 

 band sharply bordered by the broken white lines; ventral surface 

 somewhat like A. crythrocephala in having a pale throat in distinct 

 contrast to a dark chest and abdomen, but the throat is bluish instead 

 of flesh-color, and the gular folds and chest are dark blue-gray suffused 

 laterally by a brighter tone of blue; ventral surface washed posteriorly 

 with straw-color. 



Variation: — Another specimen, a female (M. C. Z. 8631) differs 

 from the male in having the dark lateral bands more distinct and the 

 longitudinal series of spots more nearly fused into lines as in A. 

 vitti punctata. A young specimen (M. C. Z. 8629) is similar to the 

 adult male except that the under parts are uniform blue-gray. 



Remarks: — The description was made of an adult male that meas- 

 ured one hundred and one millimeters from snout to vent. 

 Habitat: — Confined to Haiti where it is still common.
