Nostril in the anterior nasal ; five occipitals ; supraoculars three ; 

 supraciliaries five, second longest. Plates of the mesoptychium 

 numerous. One series of brachial plates, two of antebrachial, 

 scarcely continuous ; postbrachials small. Four series of large 

 femoral plates, bounded by smaller ones anteriorly and posteriorly ; 

 three tibial rows, two upon the inferior face of the limb, the external 

 composed of seven plates, the third very large. Femoral pores 

 fifteen. Abdominal plates in eight longitudinal series. Two trans- 

 verse marginal and three longitudinal median praeanal plates. 

 Lateral caudal plates smooth, superior keeled. Above brown ; a 

 narrow yellowish line extends from the supraciliary margin to a 

 nearer or more distant point upon the tail ; this is bordered above 

 by a black band, three times its wid th, which is sometimes faintly 

 margined above with yellowish ; sides black as far as a yellowish 

 line which extends from the superior border of the ear to the groin, 

 and thence with increased width for some distance upon the tail ;
