Diagnosis: — Nasals broadly in contact with the rostral. Pre- 
frontal region covered by a pair of irregular supranasals; nasals and 
supranasals of each side separated from each other by a single large 
scale. Frontal, frontoparietal, and occipital regions covered by uni- 
formly small scales, irregular in shape and strongly keeled. Supra- 
orbital semicircles not differentiated but the scales of the supraocular 
region smaller than the other supracephalic scutes. Two large, 
vertically arranged canthal scales on each side. Dorsal crest broadly 
interrupted on the shoulders and rump; the neck-crest half a centi- 
meter high, the body-crest only three millimeters high; color above 
brownish gray, with numerous but faint reticulations; head tinged 
with blue, chest with smoky. 
Habitat: — Turks Island, Southern Bahamas. 
Description: — Adult male, M. C. Z. 1252 Turk’s Island, Southern 
Bahama Islands, 1862, A. S. Bickmore. 
Rostral as wide as the mental, broadly in contact with the nasals; 
nasals of medium size, somewhat pentagonal perforated posteriorly 
by a semicircular nostril; each nasal in contact with a large pent- 
angular postnasal and a pair of irregular supranasals; nasals and 
supranasals of each side separated from each other by a single, large 
triangular scale, all the rest of the scales of top of head small and irre- 
gular, no enlarged prefrontal, frontal or parietal scales; a very slight 
indication of a supraocular disk; scales of the supraocular and supra- 
ciliary region as well as the outer parietal region somewhat smaller 
than the rest of the supracephalic scales; scales of the prefrontal, 
frontal, and occipital region irregular and all about the same size, 
while the scales of the supraocular and outer parietal regions are 
uniformly smaller; occipital rather large and located well forward; 
all scales of the top of head strongly keeled but hardly tubercular; 
two large, vertically arranged canthal scales on each side; a well- 
developed series of slightly keeled suboculars carried back a. trifle 
beyond the orbit, ten supralabials to the middle of the eye; a series 
of three or four rows of small scales separating the supralabials from
