Rfc^PORT OF NATIONAL MUSEUM, 1898. 



General color black, olivaceous above, with five very narrow and 

 inconspicuous greenish-white dotted stripes; one dorsal (widest) and 

 two lateral on each side. Tail and body beneath dark blue. Chin, 

 throat, and upper labials white. The upper lateral stripe along the 

 middle of the third row of scales from the median line; the lower on 

 the middle of the third from this. Scarcely a trace of the bifurcation 

 of the middle dorsal stripe; the hind legs uniform black. 



The dorsal stripe is on the adjacent edges of two rows of scales. 

 The others each on the middle of one series, thus differing from P. 

 quimpielineatiis, in which they are on adjacent edges. The lateral 

 stripes are not continuous lines, but only a succession of dots, one 

 central on each scale. The median stripe is similarly constituted by 

 dots on the adjacent edges of two rows of scales, and is usually less 

 distinct than the lateral. There is a faint indication that the remainder 



of the white dotted scales is 

 black, leaving a dark olivaceous 

 row on each side the back, each 

 scale in which sometimes has 

 a lighter center. There can 

 scarcely be said to be a bifurca- 

 tion anteriorly of the median 

 stripe. There are four entire 

 rows of scales on the back be- 

 tween the upi^er lateral stripes. 

 This species, remarkable for 

 its diminutive size, has the gen- 

 eral appearance of a very young 

 P. qninqueUneatus, but differs in 

 being darker, in having the light 

 lines very narrow and inconspicuous, not continuous, but formed by a 

 succession of whitish dots, the lateral on the centers of single rows of 

 scales instead of on their adjacent edges. The hind legs are entirely 

 black without a trace of the posterior white line. The cephalic bifurca- 

 tion is wanting. The head is shorter, higher, and more arched- The 

 dorsal is shorter. There are seven labials instead of eight. The legs 

 are much weaker and smaller, the hinder contained three times instead 

 of two and one-half or less in the head and body. The scales are fewer 

 in number. The hinder postnasal is very apt to be the first above to 

 accommodate the brevity of the muzzle. 

 This is also a species of the Central region.
