Agrees in every respect with P. cepedianum, but the ventral 

 scales are keeled, though less strongly than in P. lineatum, and 

 the segments of the tail are composed of seven transverse rows of 

 scales above and five or six on the side.

Snout twice as long as the distance between the orbit and the ear- 

 opening, or the diameter of the orbit. Tipper part of rostral with a 

 median cleft. Nostril pierced above the rostral and first labial, the 

 suture between the two plates entering its lower border ; nine or 

 ten upper labials ; eight or nine infralabials ; chin-shields irregular, 

 scarcely distinct from the surrounding scales ; two or three scaleff 

 between the naso-rostrals. Ear-opening small, round, one fourth 

 or one third the diameter of the orbit. Dorsal scales aU granular, 

 perfectly smooth. Ventral scales smooth. Femoral pores twelve 

 to fifteen on each side. Tail not much depressed, narrower than 

 the body ; segments of tail rather indistinctly marked, composed of 

 seven transverse series on the side, of nine above ; lower surface of 

 tail with a median series of transversely dilated scales, two narrower 

 ones alternating with a broader one ; all the caudal scales perfectly 

 smooth. Greenish above, with more or less numerous orange spots, 

 which, however, may be absent ; an orange streak from the ear to 

 the nostril, passing through the eye, and another, /\ -shaped, from 

 eye to eye, are generally present ; lower surfaces whitish, throat not 

 spotted. Siz» and proportions of P. cepedianum.

Snout once and two thirds as long as the distance between the 

 orbit and the ear-opening. Upper part of rostral with a median 

 cleft ; nostril pierced above and between the rostral and the first 

 labial ; eight upper labials ; seven infralabials ; chin -shields, only 

 the inner pair well distinguished from the giilar scales, which are 

 larger than in the other species, equalling the ventral scales in size ; 

 three scales between the naso-rostrals. Ear-opening small, its 

 vertical diameter not half that of the orbit. All the scales on the
