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. 



Ameiva cineracea, sp. nov. 



Description: — Adult male; Type M. C. Z. 10577. Grand Isle 

 off Petit Bourg on the coast of Guadeloupe, F. W. I.; August 24, 

 1914; G. K. Noble.

 frontal in contact with part of the first two supraoculars; a pair of 

 frontoparietals in contact with the second supraocular posteriorly, the 

 third anteriorly, separated from the posterior part of the third supra-
