REPTILIA. 289 



but distinct median ridge. Occipital about lialf tlie size of the ear opening 

 and separated from the supraocular semicircle by two or three rows of scales. 

 Supraocular disc composed of eight polygonal keeled scales, separated from the 

 semicircle by a single row of very small granular, polygonal or elongate scales. 

 Canthus rostralis composed of few scales, one extremely elongated in the middle 

 and flanked by others less elongate on either side. Superciliary ridge consisting 

 of one very long anterior shield, followed by a number of much smaller scales. 

 Loreal rows five; subocular semicircle strongly keeled; supralabials six, suture 

 between fourth and fifth being about under the centre of the eye. Temporal 

 scales small and granular, bordered above by a rather irregular zone of enlarged 

 scales, which extends from the posterior border of the orbit to a point some dis- 

 tance abo^'e the ear opening. Dorsals small, flat, smooth, showing no tendency 

 to imbricate, a median zone consisting of from three to four series of enlarged 

 more or less distinctly keeled scales. This zone commences at about the region 

 of the fore limbs. Ventrals much larger than dorsals, imbricate and distinctly 

 but not strongly keeled. Fore limbs above with rows of very strongly keeled and 

 enlarged scales, similar scales being also present on the anterior aspect of the 

 thigh. Subdigital expansions feebly developed, consisting of about eighteen 

 transverse lamellae under phalanges II and III of fourth toe. Tail strongly 

 compressed with about fifteen evident verticils along its proximal region. Each 

 of these is separated by about seven vertical rows of keeled scales. Upper edge 

 feebly serrated, each section with four small spines. Dewlap very large and 

 capable of great dilation, extending along the mid\'entral line to a point consid- 

 erably posterior to the line of the axillae. A very few feebly enlarged postanal 

 scales. No dorsal fold. 



Color of living animal, grayish and reddish brown, \-ariously marbled with 

 spots, blotches and wavy bands of dark brown or black. Belly pale ashy or 

 greenish. Dewlap fine rich lustrous maroon (blackish in alcohol). 



A single specimen only found resting upon the thatched roof of a nati\-e 

 house. I was told that it was a species which was only rarely found. A most 

 observant young Cuban, Lucio Alfonso, who was with me at the time, said that 

 it was a lizard, very partial to thatched roofs. In general habit it resembles /I. 

 sagrei, but head, body, and limbs are much more slender. 



Named for my friend. Dr. John Lewis Bremer, of the Harvard INIcdical 

 School, who has often most kindly aided me while upon collecting trips.
