the front margin of the eye and the nasal shield, the bottom 

 of wbich chiefly consists of the elongate concave loreal shield 

 and, on a narrow rand at the eye, of the narrow lower prseo- 

 cular. The upper margin of the pit is formed by the elon- 

 gate superior preeocular, which is bent över the opening, 

 partl}^ covering it, and by the prsefrontal; below the pit is 

 bordered by the second and third upper labials. The eye half 

 the length of its distance to the snout, with a round pupil. 

 Rostral just visible from above, much broader than deep. Two 

 internasals broader than long, considerably smaller than the 

 large prsefrontals, which also are broader than long. Nostril 

 in a semidivided nasal. Loreal elongate and concave; two 

 prseoculars, the lower vertical, high, and narrow, the upper 

 horizontal, elongate, and narrow, together forming a right 

 ängel at the upper posterior corner of the loreal pit. Fron- 

 tal hexagonal, contracted behind, 1^/4 as long as broad. 

 Supraoculars as broad as the middle of the frontal. Post- 

 oculars two; temporals 1 + 2; upper labials 7, third, fourth, 

 and fifth entering the eye. Lower labials 7 — 8; three or four 

 of them in contact with the anterior chinshields, which are 

 short and broad in conformity with the posterior. Body 

 stout, cylindrical. Scales smooth, in 17 rows, without apical 

 pits, the vertebral row not enlarged. Ventral shields 135 — 

 141; anal entire. The tail short, conical, with 31 — 33 pairs 

 of subcaudals. 



Above brownish black, a little lighter on the sides; each 

 scale with numerous small white döts. The head is a little 

 more brownish than the body, each shield with small white 

 döts. On some of the upper and lower labials there is a 

 distinct white ocellar spöt. The ventrals and the subcaudals 

 paler brownish with dark edges and white oblong spöts, each 

 of these not occupying more than a single ventral or sub- 

 caudal shield. On the specimen N:o 2066 the white ventral 

 spöts are very distinct and numerous, on the other two they 

 are distinct on the sides of the shields but disappear on 

 the middle parts.
