Desceiption. — The principal characters have already been 

 given in describing the genus. The head is contained 

 seven times in the length of the trunk ; the scales of the 

 temples are imbricated, and differ but little from those of 

 the neck; the ear-oj)ening is small and oval, placed di- 

 rectly behind the angle of the gape ; the scales on the 

 sides of the neck are small, smooth, rounded behind, and 

 much imbricated ; the lateral furrows are deep, clothed 

 with small lozenge-shaped scales. Across the body, 

 from the head to the origin of the tail, are 100 bands 

 of scales, forming sixteen longitudinal rows, the two outer 

 of which on each side are concealed by the lateral fold ; 

 beneath the body, from the throat to the vent, are 115 

 transverse rows, forming ten longitudinal rows of scales ; 

 round the tail are 240 rings of scales ; all the scales of the 

 upper parts become bony with age ; their shape on the 

 neck, back, and sides is subrhomboid, beneath it is hex- 

 agonal ; they are wider than long, and shghtly notched on 

 their hinder edges ; the scales of the tail are keeled at 

 every age, as are those of the whole body (except the 

 throat) in the young. In the adult animal, the head and 

 fore-part of the neck is greenish ash ; the upper surface 

 of the body in general is reddish chestnut, each scale being 

 dotted with black, parts beneath yellowish brown. 



The coloiuing of the young is very different, being
