apical grooves ; eight upper labials, the fourth and fifth enter 

 the orbit, and of the third the upper hinder angle is detached and 

 forms a small lower anteocular ; uniform olive above, pale yellowish 

 below and on the upper labials ; some of the ventrals partially black- 

 ish near their bases, as recorded by Gr ii n t h e r. 



b. and c. — These are two young specimens, measuring respectively 

 16f (of which tail 3£) and 14 J (of which tail 2£) inches; in both 

 the ventrals are 244, and the subcaudals 85 and 89 respectively. 

 The scales are smooth, only in some parts on the posterior body 

 scarcely perceptibly keeled, all with minute apical grooves. In h the 

 shields of the head are perfectly regular, as described by G ii n- 

 t h e r, three upper labials enter the orbit ; in c, the posterior por- 

 tion of the third upper labial is detached forming, as in the old 

 specimen, a small lower anteocular, and moreover the large anteocu- 

 lar extends so far to the top of the head that it touches the vertical. 

 The colour of both young specimens above is a pale olive grey 

 with a dark blotch on the top of the head, extending over the 

 vertical and the occipitals ; the middle of the back is marked 

 with numerous, rather wide blackish cross bands separated by in- 

 terspaces of equal width, they become gradually obsolete on the tail ; 

 sides of the body densely reticulated with black ; all ventrals more 

 or less distinctly edged with dark, the larger basal spots being very 

 conspicuous throughout ; subcaudals uniform yellowish white.

Not common about Moulmein and to the south of it. One specimen 

 measured 23£ inches of which the tail was only 1*4 inches; the black 

 spots are at the neck in 5, round the middle of the body in 6 

 longitudinal series. 



On the Andamans the species is also very common and attains a 

 length of 40 inches, the tail being sometimes more than one third, in 

 other specimens, however, scarcely more than one fourth of the total
