SCHMIDT, THE HERPETOLOGY OF PORTO RICO

The most frequent coloration is a grayish brown of varying shade, 

 sometimes reddish, sometimes nearly black, which may be uniform or 

 mottled. In the lighter specimens there is nearly always a dark inter- 

 orbital mark, and in a few the snout is white in front of this, either with 

 a broad transverse Avhite band or completely light to the tip of the snout. 

 There is usually also a dark subcanthal mark, interrupted by the eye, 

 and continued over the ear for a short distance. In a few cases the 

 dorsum is spotted irregularly with vivid white spots. Of one hundred 

 and ninety-four examined, eighteen have a light line beginning at the

snout and passing over the edge of the eyelid to the ear, continuing as a 

 broader light dorsolateral band to the thigh. In nineteen specimens 

 there is a sharp median white stripe (compare Fowler. 1918, Fig. 2). 

 Five have a broad median light band, about four times as broad as the 

 more common narrow line. The hind legs are occasionally distinctly 

 barred, more usually indistinctly barred or uniform. The concealed sur- 

 faces of the thighs are often bright pink or red. The venter is usually 

 light and unspotted, occasionally spotted with groups of dark-brown 

 punctuations. In no specimen were the concealed surfaces of the thighs 

 reticulated with the fine or coarse dark network of K. antillensis.
