8 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 92 



heavily keeled, imbricate, about ii equalling the standard distance 

 from snout to center of eye ; no middorsal differentiated zone ; laterals 

 like the dorsals, ii in the standard distance; mental moderately large, 

 followed by two enlarged postmentals ; scales of gular region small, 

 smooth, not imbricate anteriorly, but becoming imbricate and decidedly 

 keeled on the throat ; scales of chest and belly smooth, rounded, im- 

 bricate, about 9 ventral scales to the standard distance, not perfectly 

 regular in size ; scales of limbs anteriorly and below like those of the 

 belly, much smaller and granular posteriorly; lO smooth lamellae 

 under the fourth toe ; scales of proximal part of tail above keeled, 

 regular and obtusely pointed, on reproduced part smooth, irregular and 

 rounded ; below on the proximal part with a larger median and two 

 smaller bordering rows of enlarged hexagonal scales, on the reproduced 

 part with a median series of transversely enlarged plates, rather 

 irregularly arranged. 



Dimctisions. — Head and body, 26 mm; tail (reproduced) 20 mm; 

 width of head, 5 mm ; tip of snout to ear, 7 mm ; fore leg, 7 mm ; hind 

 leg, 9 mm. 



Coloration in alcohol. — Female : body color above pinkish buff ; 

 head with a lateral sepia stripe beginning at the nostril, passing through 

 the eye, widening behind the eye and passing upward to meet its fellow 

 in a pair of diamond-shaped spots on the occiput; a dark median 

 stripe beginning on the rostral, narrowing between the eyes, widening 

 again and ending in a diamond-shaped spot on the posterior part of the 

 head ; traces of a dark stripe leading from the corner of the mouth onto 

 the sides of the neck and then dorsally ; back with numerous wide, 

 dark, wavy crossbands which tend to break up posteriorly into very 

 irregular transversely arranged spots ; tail with a continuation of the 

 posterior dorsal coloration ; a wide, dark, light-edged stripe beginning 

 on the flanks just anterior to the groin and continued onto the tail 

 where there are traces of a dark line bordering it below ; ventral 

 surfaces pale olive-gray, suffused with very minute gray punctulations 

 which are especially numerous on the posterior part of the belly and 

 beneath the legs and tail ; upper surfaces of limbs with alternating 

 light and dark crossbars. The coloration of the male is not known. 



Paratypc. — A single paratype, U.S.N.M. no. 81447, also a female, 

 was taken on Long Cay, oft' South Caicos, on the same day as the type. 

 It is essentially the same in scalation, having 1 1 dorsals to the standard 

 distance. Only the lateral scales of the throat of the paratype appear 

 to be keeled ; the central ones are smooth, like the gulars which precede 

 them. There are nine lamellae on the fourth toe. The color pattern 

 on the head is very similar to that of the type ; the body however, is
