Plate 3. 



Type, an alcoholic skin, M. C. Z., 10534, Ca^onan Islands, probably 

 from Cayman Brae, 1911, W. W. Brown, Jr. 



This species is so closely related to C. viacleayi 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. viacleayi; 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,
