4 ON THE WEST INDIAN TEIID^J 



is another band of smaller ones ; mesoptychials nearly as 

 large as gulars, in six to eight series, reaching across the 

 lower surface. Dorsal granules small, smooth. Ven- 

 trals in fourteen rows, outer small, transverse series thirty- 

 one to thirty-three. Anteriorly on the chest there is no 

 intrusion of granules between the median series of plates. 

 Preanals most often in transverse series, two to six of the 

 median plates enlarged ; sometimes with three larger 

 shields arranged in a triangle. Brachials moderate, in 

 three or four rows, second row largest ; antebrachials in 

 three rows, outer broad ; postbrachials small. Ten or 

 eleven rows of femoral plates, and four or five of tibials. 

 Femoral pores eighteen to twenty-two. Digits serrated ; 

 fifth toe shorter than inner. Caudals keeled. 



Four of the specimens from Grenada have the frontal 

 divided transversely, near its posterior extremity ; the 

 other four from the same locality are normal and agree 

 with those from St. Vincent, thirty-nine in number, none 

 of which possess the divided frontal shield. 



Adults are brown on the back and more or less mottled 

 with black. The flanks are darker in the upper half, 

 more olive in the lower, marked with four to six longitu- 

 dinal rows of small, rounded, dark edged spots of white. 

 Beneath olivaceous, clouded or marked with lighter, and 

 at the edges of the flanks marked with black. In front 

 and beneath, the thighs are blotched with black and yel- 

 low. The white spots also form vertical or transverse 

 series in many cases. 



Young with a series of about seventeen transverse bands 

 of brown, separated by spaces of equal width and bisected 

 by a narrow line of lighter color along the vertebrae from 

 the back of the neck. From the eye to the base of the 

 tail a dark band runs along the upper edge of the flank ; 

 posteriorly it is broken into spots ; along the body its
