BARBOUR AND NOBLE: LIZARDS OF THE GENUS AMEIvVA. 443 
area between the two throat folds several rows of scales considerably 
enlarged; under side of body with ten longitudinal and thirty-two 
transverse rows of plates; preanal plates irregular, in pairs, the posterior 
pair largest and with a small median scale wedged between; a row 
of large brachials hardly continuous with a row of large antebrachials; 
a few large postbrachials; four series of femoral plates; two series of 
tibials inner small; (details of plates on arms and legs fide Boulenger, 
as the photographs do not show these characters distinctly); eighteen 
femoral pores; upper scales of tail oblique, scales of sides smooth, 
others indistinctly keeled. 
Coloration: — Dorsal region olive-gray; on each side three longi- 
tudinal white lines, the upper faint; the interspace between the two 
upper white lines brown-black; between the two lower lines dusky; 
limbs gray flecked and lined with darker; lower surfaces greenish 
white; according to Boulenger, a white black-edged line along the 
hinder side of the femur and tibia and the anterior side of the latter. 
Remarks:— The type is in good preservation; ‘it measures 2;3” 
from snout to vent and the tail is 574” long. 
The species is confined to the Isle of St. Croix (Santa Cruz), where 
it is either extremely rare or perhaps quite extinct. Recent collectors 
have been unable to secure specimens.

Haiti, but undoubtedly one of the types from Sombrero. 
Rostral forming an acute angle behind; nostril on posterior border 
of anterior nasal; anterior pair of nasals just in contact behind rostral; 
frontonasal longer than wide in contact with the loreal; prefrontals 
broadly in contact; frontal in contact posteriorly with the first 
supraocular, for nearly its entire length with the second; a pair of 
frontoparietals separated from the third supraocular by a single row 
of granules; eight occipitals in a transverse row of three pairs plus 
a single terminal scale on each side; seven supraciliaries; four supra- 
oculars, the first separated from the loreal; three posterior supraocu- 
lars separated from the supraciliaries by a single, partly double row of 
granules;~ last supraocular separated from the outer occipitals by 
three rows of small scales; seven large supralabials; five or six infra- 
labialss between infralabials and chin-shields a wedge of a single 
row of granules extending anteriorly to the first chin-shield; chin and 
throat covered with minute granules, an indistinct band of very slightly 
larger ones extending across the middle, the median ones forming an
