covered with two series of large scales or plates and three smaller ones; 

 thirteen or fourteen femoral pores; under side of the tibia covered 

 entirely across by three plates, of which the upper is larger than the 

 other two together; upper side of the wrist with three series of en- 

 larged plates; outer toe extending far beyond the inner (first) toe 

 almost to the claw of the second; tail covered with smooth scales, 

 the scales being oblique with parallel sides, except for the median 

 row which is wedge shaped; about twenty-two scales in the fifteenth 

 ring from the base. 



Coloration: — Above dark brownish olive with seven , distinct 

 greenish white longitudinal lines, the median one somewhat wider 

 than the others and starting from the tip of the tip of the snout, while 

 the others originate in front of the eye, and continue some distance 

 on the tail except for the outer row which terminate in the groin; 

 upper side of limbs also dark olive-brown with very distinct round 

 greenish white spots; under side greenish white darkening on tail. 

 Mr. Wetmore describes the tail of the living animal as varying from 

 brilliant emerald-green to grayish blue according to light, and the under 

 side as dull clay-red." 



Remarks: — The description was taken from the type and only 

 known specimen; it measured forty -seven millimeters from snout to 

 vent. It is probable that the specimen was about half grown. 



Habitat: — An extremely rare and local form known only from 

 Guanica, Porto Rico. 



Ameiva polops Cope.

 prefrontals broadly in contact; frontal in contact with the second,

 are separated posteriorly by a very few small granules) ; five occipitals, 

 the two bordering the median the largest; eight supraciliaries ; four 

 supraoculars; last supraocular separated from the outer occipitals
