BARBOUR AND NOBLE: LIZARDS OF THE GENUS AMEIVA. 453 
nal and thirty-five transverse rows of plates; preanal plates in a 
marginal row, the two median largest and in a pair of large median 
plates just anterior to these; on the lower arm one row of wide and 
two of very narrow antebrachials, grading into four or five rows of 
smaller scales near the elbow joint; on the upper arm two or three 
rows of brachials scarcely larger and grading into the granules of the 
arm; on the posterior side near the elbow a small group of slightly 
enlarged postbrachials; under side of the thighs covered distally with 
four rows of plates, outer row much the wider, breaking up proxi- 
mally into ten or twelve smaller rows; femoral pores twenty-nine and 
thirty; on the under side of tibia four rows of plates those of the outer 
being very much enlarged; upper side of the wrist covered with gran- 
ules; outer toe extending a little further than the inner, tail covered 
with straight, keeled scales; about thirty-nine scales in the fifteenth 
ring from the base. 
Coloration:— Upper and lateral surfaces uniform dark brown tinged 
with olive-green anteriorly with bluish gray posteriorly; ventral 
surface dark blue-gray spotted laterally with turquoise-blue of low 
intensity. 
Remarks:— The description was made of an adult female that 
measured one hundred and four millimeters from snout to vent. 
The type is the only recorded specimen of this species. It is interest- 
ing to note the almost melanotic coloration of the Ameivas from the 
small islands of Sombrero and Redonda, which parallels that of the 
wall lizards (Lacerta) of Filfola and other rocky islets of the Mediter- 
ranean. 
Habitat:— Confined to the small island of Redonda.

Rostral forming slightly more than a right angle behind; nostril

rostral; frontonasal longer than wide in contact with the loreal; 
frontal in contact with part of the first two supraoculars; a pair of
