before and then, on the extreme hxteral margin, a moderately 

 dark brown stripe. Hence we have, on each side of the 

 broad median stripe, five bands of ground colour alternating 

 with five narrow brown stripes of varying intensity, the 

 middle one of the five being the darkest and broadest. The 

 inner margins of the narrow brown stripes are less well 

 defined than the outer and tend to shade off into the ground 

 colour. The horse-shoe-shaped anteiior extremity is dark 

 brown. The ventral surface has also a characteristic pattern 

 (Fig. \h). The ground colour is white. In the middle line 

 there is a moderatel}' broad band of ground colour with no 

 markings, slightly broader around the external apertures 

 (which lie in it) than elsewhere. On either side of this 

 median band, and extending almost to the margin of the 

 ventral surface, is a very broad band of ground colour spotted 

 all over with small flecks of light brown. The brown flecks 

 are pretty evenly distributed except at the outer maigin of 

 the spotted band, where they are closer and run together 

 into an irregular, very narrow stripe. Outside this stripe a 

 narrow band of white, with no flecks, extends to the outer 

 margin of the outermost of the narrow brown dorsal 

 stripes. 



Only two specimens of this very handsome species were 

 obtained.

I have some little hesitation in making this identification. 

 The characters of the species are not at all striking and there 

 w^ere only a few specimens in the collection. When the 

 animal is crawling the body is very long and narrow, 

 strongly convex on the dorsal surface and flattened on the 

 ventral. It scarcely tapers at all to the anterior extremity 

 but tapers gradually posteriorly. One specimen measured 

 60 mm. in length by 17 mm. in gi-eatest breadth when 

 crawling. In spirit "the peripharyngeal aperture is situated 

 in about the middle of the ventral surface and the_ genital 

 aperture about half way between it and the posterior end. 

 The eyes are arranged as usual in the genus, viz., a single 

 pair placed a short way behind the anterior extremity. The
