united all the several forms, formerly described, into one spe- 

 cies, divided into a great many varieties of coloration; his 

 list of varieties may find a place here. 



A. A white labial band, extending along the side of the body. 



1. The band very narrow and bordering the lower lip only. 



Var. A. The sides of the head between the labial white line and a more 

 or less distinct narrow line from the tip of the snout along the 

 canthus rostralis and above the eye to the nape, dark brown; 

 the belly darker towards the narrow lateral white band, which 

 is edged inferiorly by a fine brown line; the rest of the body 

 uniform, with minute dark dots. 21 series of scales. 



Var. B. As in the preceding, but the white lateral line edged above with 

 a darker band of the same tint as the belly, which band is 

 again edged with a rather indistinct lighter band ; belly scarcely 

 darker than the back, with white dots or shafts. 21 series of scales. 



2. The white labial band is broad and occupies both the upper and the 

 lower lip, entering the eye. 



Var. C. In all other respects like Var. A. 21 series of scales. 



Var. D. Light grey, the lateral band passing through the eye and the 

 lower surface of the head dark brown; the white lateral band 

 soon splits up into several bands, separated by darker ones ; belly 

 with darker longitudinal bands and whitish dots. 21 series of scales. 



Var. E. Five or seven regular longitudinal dark bands on the body, the 

 ventral one dividing into two on the nape, uniting again on 

 the tip of the snout. 19 or 21 series of scales. 



B. No white labial band. 



Var. F. Pale grey, abdomen a little darker; throat dark brown, whitish- 

 spotted on the sides; lips with small dark vertical bars; back 

 with several rather indistinct darker longitudinal bands; belly 

 white-spotted. 21 series of scales. 



Var. G. Like Var. E., but with spotted lips as in var. F. 19 series of scales. 



Var. H. No longitudinal bands, but generally a series of small distant 

 black spots along each side of the back; lips spotted as in F. 

 and G. ; belly white-spotted. 19 or 21 series of scales. 



Var. I. Uniformly light-coloured, with a few small dark dots above and 

 below. 19 or 21 series of scales.
