elongate, narrow, twice as long as broad, separated on the mesial line by 

 the interparietal and, in cases, by a small scale behind it. In front of the 

 interparietal there is a pair of small shields, and in front of them one or 

 more small ones. The number of plates between the supraoculars and 

 interparietal varies from three to five. Two pairs of the supraorbitals are 

 in contact across the forehead behind the frontal. Three cross-rows of 

 plates behind the internasals. Frontal medium, hexangular. A pair of 

 larger prefrontals, in front of which there is a second pair of smaller 

 ones, the two pairs being sometimes separated at their inner angles by a 

 small lozenge-shaped plate. Internasals elongate, narrow, with the acute 

 posterior extremity directed obliquely outward. Auricular scales two to 

 three, broad, upper largest. Scales in front of ear moderately large, 

 smooth. On the sides of the neck the skin is strongly folded, covered 

 with keeled small scales. Dorsal crest low. Dorsal scales mucronate, 

 the keels obliquely turned toward the vertebral line. The scales of the 

 flank are smaller and rather abruptlj^ turned upward. The ventrals are 

 about as large as the dorsals, smooth, broader than long, and rounded on 

 posterior margin. There are forty- one to forty-three rows of scales, count- 

 ing around the middle of the body. The adpressed hind limb does not 

 reach the eye. Tail feebly compressed, more than one and one-half times 

 as long as the body, with a crest a little stronger than that of the back. 



Olive brown, with a metallic lustre, clouded with dark brown, which in 

 earlier stages was apparently arranged in transverse bands. Faint indica- 

 tions of a light band on the upper edge of each flank. Olivaceous beneath, 

 lighter backward and sprinkled or clouded with mauj- small spots of 

 white. 1 ail ringed with brown, about seventeen rings. Chin and throat 

 clouded or reticulated with olive and white. A light band from the hinder 

 angle of the eye to the angle of the mouth. Lighter scales sprinkled over 

 the body and limbs, both above and beneath. 



This species is allied to L. eremitus Cope from Navassa, and with it to 

 L. carinnfus of Cuba and the Bahamas, more than to the others. The 

 distinguishing characters appear in the scales of the head, in the relative 

 sizes of those of the body, and in the coloration.

Half-grown examples are grayish-brown to brownish-gray, white be- 

 neath. Tlie top of the head is nearly uniform brown. From each nos- 

 tril through the eye to the shoulder there is a lighter edged brown band ; 

 these bands converge in approaching the shoulders. From the shoulders 

 backward there are brownish darker edged blotches, each of which pre- 

 sents an angle toward the vertebra', thus enclosing lozenge-shaped lighter 

 spots on the median line. On the sides of the tail these lateral blotches 

 alternate, or, meeting, form transverse bands of brown. Labials brown, 

 with or without whitish spots. Chin mottled with brownish. The color
