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 
briliant 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. Itis probable that the specimen was about half grown.
