Suout broadly rounded ; rostral small, just visible from above ; 

 froutal louger than broad; supraocular much larger thau the eye, 

 louger thau the prsefroutals ; temporal two thirds or three fifths the 

 length of the parietals. Diameter of body 37 to 50 times in the 

 total length. 15 scales round the middle of the bodv, 17 behind 

 the head. Ventrals nearly twice as broad as the coutiguous scales, 

 163-175; subcaudals 8-16. Caudal scales smooth or a few of 

 the terminal ones inconspicuously hi- or tricarinate ; terminal scute 

 with a trausverse ridge which is hardly distinct in the female. 

 Adult reddish brown or brick-red above, with three continuous or 

 interrupted black longitudinal lines ; young (P. bilineatus, Bedd.) 

 dark brown or black above, with two yellowish dorsal bauds ; 

 yellowish below, each scale with a brown dot. 



Total length IG inches.

Very closely allied to the preceding, but head-shields rather 

 shorter and supraocular not longer than the prsefroutals. Dia-
