BARBOUR AND NOBLE: LIZARDS OF THE GENUS AMEIVA. 477 
Remarks:— The description was made of an adult male that meas- 
ured seventy-four millimeters from snout to vent. 
Habitat:— Apparently confined to Guatemala, and perhaps only 
found locally; the specimens before us are labeled simply Guatemala. 
AMEIVA EDRACANTHA Bocourt. 
Since it is impossible to examine a specimen of this species we are 
obliged to use this condensed form of the original description (Bocourt, 
Ann. sci. nat., 1874, ser. 9, 19, art. 4). 
Description:— Nostril between the two nasals; frontal proportion- 
ally large; frontoparietals united (perhaps abnormally); three occipi- 
tals; three supraoculars; six supraciliaries; supralabials and infralabials 
each five, the infralabials more attenuated and extending further be- 
hind; gular scales arranged like those of A. ameiva, but larger; on the 
portion between the two throat folds two or three rows of enlarged 
scales; under side of body with eight longitudinal rows of scales; a 
single oval preanal plate surrounded by small scales; on each side of 
this region six or seven spinose plates; on the upper arm a single row 
of brachials; under side of thighs covered with three rows of shields; 
twelve or thirteen femoral pores; on the under side of the tibia two 
rows of scales; caudal scales keeled. 
Coloration:— Ground color olive-green, five yellowish longitudinal 
lines, the median beginning at the occiput and ending before the thighs, 
the second and third on each side running the length of the bodies, 
finally those of the flanks are a little less distinct and often broken; 
back and side with transverse dark brown lines; limbs and tail spotted 
with the same color; ventral surface yellowish.

Rostral forming about a right angle behind; nostril between the 
two nasals; anterior pair of nasals broadly in contact; frontonasal

frontoparietals, which are formed of four or five scales in two longi- 
tudinal rows separated posteriorly from each other by a wedge of four 
scales, and separated from the supraoculars by one or two rows of 
granules; three large occipitals in a transverse row surrounded pos-
