162 THE HERPETOLOGY OF CUBA. 



ciliaries and the supraorbital semicircles bounding the area of the supraorbital 

 granules anteriorly; canthus rostralis sharp, consisting of five or six elongate 

 shields which are continuous with the superciliaries ; loreal rows five or six; 

 subocular semicircles in contact with supralabials ; supralabials six, the suture 

 between the fifth and sixth under the centre of the eye; temporals excessively 

 minute, granular, no enlarged series forming a supratemporal fine; dorsal and 

 lateral scales nainute, granular, none on the middorsal hne enlarged; ventral 

 scales medimn in size, flat, imbricate, without trace of keel; scales of throat 

 and chest also smooth; fore limbs above with small, imbricate, very feebly 

 keeled scales, smaller than the ventrals; femur and tibia with similar but 

 sMghtly larger and smooth or very feebly keeled scales; fingers and toes above 

 not distinctly carinate; digital expansion narrow, above fifteen lamellae under 

 phalanges II and III of fourth toe; tail (broken in tjrpe) ; long in U. S. N. M. 

 26,731, compressed, without a "fin," divided into irregular segments of about 

 five keeled scales each, the hmiting row of each segment slightly enlarged) ; 

 in type, dewlap rather large, with smooth scales, anterior edge slightly thick- 

 ened; postanal scales not enlarged. 



Colour (in Ufe) : — Mottled gray-brown, of more or less a "salt and pepper" 

 appearance. Dewlap white, with a large rich red-brown spot at its base, sur- 

 rounded by the white; the scales of the brown area white Uke the rest, the skin 

 only coloured. Belly whitish but throat with longitudinal dark Unes. 



There is marked variation in the degree of carination of the head-shields; 

 U. S. N. M. 26,931 has them almost smooth, yet we do not beUeve that this 

 specimen represents a different species. The species seems to be one which is 

 found almost wholly along the edges of woods on the trunks of trees and in 

 shrubbery. It was observed frequently in March 1915 in the Valley of Luis 

 Lazo (Barbour) though a few only were secured, a circmnstance undoubtedly 

 due to a necessarily hasty ending of a collecting trip owing to the illness of 

 Mr. W. S. Brooks. 



We recognized the species at once in Ufe as one completely unknown to 

 us and one which we have not seen elsewhere during many journeys throughout 

 Cuba. We do not beUeve that this species is rare but it is probably one which 

 is usually mistaken for A. sagrei. It should be looked for among any of the 

 limestone ranges of Pinar del Rio Province.
