16 ON •WEST INDIAN REPTILES. 



ear-opening, separated from the snpraorbital series by one 

 to three rows of small scales ; rostral canthus sharp, of 

 four or five scales ; loreal rows four to five ; six or seven 

 labials to below the centre of the eye. Ear opening mod- 

 erate, vertical diameter elongate. Gular appendage large 

 in the male, with smooth scales. A low dorso-nuchal fold 

 bearing a couple of rows of larger, blunt keeled scales which 

 increase in size toward the middle of the body. Body 

 slightly compressed. Dorsal scales small, obtusely keeled, 

 larirer than those on the flanks, much smaller than the 

 (smooth or faintly keeled) ventrals. The adpressed hind 

 limb reaches the eye ; digital expansions moderate, twenty- 

 five lamellae under phalanges ii and iii of the fourth toe. 

 Tail somewhat compressed, not twice the length of head 

 and body, with unequal-sized scales, which mark the seg- 

 ments ; crest low in female, higher in male. All of our 

 specimens are adult, but none bear the fin-like expansion 

 of JiLi'phositnis. Enlarged post-anal scales on the male. 



Light grayish or yellowish brown profusely spotted 

 with large spots of black, separated b}' spaces of equal 

 width, often confluent on the back and behind the head ; 

 the three series, or lines, on each side of the head, the 

 median from the eye, converge toward the back of the 

 neck. On the flanks there are three to four rows of spots, 

 arranged in ten or a dozen transverse series, the upper of 

 which are frequently confluent, forming transverse bands. 

 The top and sides of the head are yellowish, and spotted 

 with large black spots. The ventral surface is whitish. 

 On a female the ground color is a little darker and the 

 spots less distinct and more elongate. 



Eggs supposed to belong to this species — sent with a 

 lot made up entirely of males — have a leathery envelope 

 and measure in length al)out Ave-, and in width about 

 three-tenths of an inch.
