14. GERRHONOTUS 449 



sal series on body 16 (rarely 14 or 14 2/2). Number of 

 transverse series between interoccipital plate and backs of 

 thighs varying from 52 to 56. A band of granules along 

 each side from the large ear-opening to the anus, usually 

 hidden by a strong fold. Ventral plates about size of dor- 

 sals, smooth, imbricate, and arranged in 12 longitudinal ser- 

 ies. Number of scales between symphyseal plate and anus 

 varying at least from 63 to 65. 



The ground color above in adults is olive, brown, red- 

 dish, or grayish olive, usually paler (but sometimes black) 

 on the sides, and crossed on the neck and body by from 12 

 to 14 continuous, irregular black or dark brown bands. 

 These bands usually are of about the width of one trans- 

 verse row of scales, but are undulate and sometimes more 

 or less diffused on the back. The lateral scales which these 

 bands occupy are tipped with white. The caudal markings 

 are similar to those on the body, but usually less definite. 

 The head and limbs may be unicolor or irregularly spotted 

 or mottled with darker brown. The lower surfaces are yel- 

 lowish or grayish white, with dark lines along the middle of 

 each longitudinal row of scales. The dorsal markings are 

 absent in a very young individual.
