the fourth vow and adjacent edges of the 3d and 5th. It is not 



entirely yellow, but has a light reddish stripe through its centre. 



There are faint indications of a repetition of these marks of similar 



character farther behind, but the specimens do not show them 



distinctly.

Owing to the mutilation of the head of the single specimen in our 

 possession, it is impossible to describe this with any degree of accu- 

 racy ; in its general relations, however, it has the plates much as in 

 the preceding species. 



A longitudinal dorsal band, sis and two half-scales wide, olive- 

 brown, each scale with a rather deeper spot in the centre; the four 

 and a half scales on each side of this band yellow, each row with 

 a narrow brown stripe through its centre, fading out in the tail. 

 There are thus five dark stripes on each side, the fifth above margin- 

 ing the dorsal band. Of these stripes, the 1st and 3d are narrow, 

 each showing a stripe of yellow of the same size on each side of it ; 

 the 2d and 3d are closer to each other and broader. Beneath yel- 

 lowish, with a distinct dark stripe on each side, just within the external 

 row of dorsal scales. The scutellte otherwise immaculated, except a 

 few scattered dots towards the head, exhibiting a tendency to ar- 

 rangement in two rows. Extreme bases of all the scales black.
