 Descri/ption of No. 886. — The head is much longer 

 than broad. The rounded snout is longer than the dis- 

 tance between the eye and the ear opening. The lips are 

 very prominent. The ear opening is a narrow slit, about 

 the length of the pupil, and has a slight denticulation pos- 

 teriorly. The scales on the eyelids form a rather con- 

 spicuous comb. The slender digits are covered below 

 with a series of transverse lamellse, terminated by two 

 large plates which are somewhat rounded and wider dis- 

 tally than proximally. The nostril is pierced between 

 the rostral, first labial, and three nasals, the upper of 

 which is in contact with its fellow of the opposite side. 

 There are seven upper and six lower labials ; the last of 

 each, under the pupil, is very small. The two plates be- 

 hind the large pentagonal mental are followed by several 

 about the size of the dorsals, which are in turn' gradually 

 replaced by the small flat gulars. The back and limbs 

 are covered with smooth, flat, rounded, equal sized scales, 

 without tubercles or granules. The muzzle has convex 

 plates, smaller than the dorsals, but larger than those on 

 the occiput, which are also convex. The lower surfaces 

 are covered with smooth flat scales, larger than those on 

 the back. The conical tail is slightly flattened at its base,
