 bricate, towards the collar ; latter angular, attached in the middle ; 

 sides of neck folded. Back covered with small flat roundish sub- 

 triangular feebly keeled tubercles forming regular longitudinal and 

 transverse series separated by minute granules ; the tubercles 

 becoming smaller and passing into the granules on the flanks ; a 

 lateral fold. Yeutral scales large, quadrangular, broader than long, 

 juxtaposed, forming twelve or fourteen longitudinal and thirty-three 

 or thirty-four transverse series. Pra^anal scales rather irregular, 

 generally a posterior pair enlarged. Limbs above with imbricate 

 strongly keeled scales, interiorly with smooth or granular scales. 

 Femoral pores in two or three rows in the males, the inferior row 

 composed of six to ten pores. Caudal scales smooth or feebly keeled 

 inforiorly, strongly keeled above, and spinose on the sides ; on the
