 gular flat granules, intermixed with large trihedral tubercles, forming 

 about fourteen irregular longitudinal series. Abdominal scales 

 rather small, subhexagonal. Males with 7 or 8 prseanal pores, 

 forming a slightly angular series. Tail cylindrical, slightly 

 depressed, verticillate, with rings of keeled tubercles ; no enlarged 

 scales inferiorly. Colour sandy, with darker spots which may
