This species is so closely related to C. macleayi from Cuba that a 
detailed description is superfluous. The distinguishing characters of 
the species are adequately presented in the following diagnosis. 
Diagnosis:— Scales covering the upper surface of the snout some- 
what similar to those of C. macleayi; enlarged frontal shield separated 
from the prefrontals by five irregular rows of small scales instead of 
two rows of large ones as in C. macleayi. Scales of the frontoparietal 
region much smaller and more numerous than those of C. macleayi. 
Supraorbital semicircles not differentiated from the frontoparietal 
scales. Canthus rostralis consisting of three short, rather oblong 
scales, all about the same size. Dorsal crest not interrupted on either 
shoulders or rump, not reduced at all on the shoulders, considerably 
reduced on the rump; forty-four scales in the dorsal crest from 
shoulders to rump, all spines of this section very low, scarcely over 
2 mm. high; spines of the neck and tail-crest about twice as high as 
these on an average. Limiting row of each verticil formed of scales 
several times as large as the other verticil scales, the row preceding 
the limiting row somewhat wider than the other rows. Coloration 
like C. macleayi but very much paler and grayer; an indication of 
regular pale yellow blotches along the median line of the back; no 
stripes or markings on the sides. 
Habitat:— Cayman Brae and Little Cayman.
