BARBOUR AND NOBLE: LIZARDS OF THE GENUS AMEIVA. 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^^" 

 from snout to vent and the tail is Sjg" 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. 



Ameiva corvina Cope. 



Description: — Adult male; Type M. C. Z. 3616. Labeled Jeremie, 

 Haiti, but undoubtedly one of the types from Sombrero.

 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- 

 labials; 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
