BEPTILES OF BBITISII BlUMA. 5o 



vertical bauds down the body, and, in one specimen, traces of a 

 white collar. Two specimens are in the Museum of the 

 Asiatic Society of Bengal, presented by Major Berdmore, from 

 Teuasserim. 



In the young the hend-shields arc rather irregular. The 

 anterior frontals are yery small. In one specimen the vertical is 

 an equilateral rhomboid. The posterior frontals in some enter 

 the orbit. The superciliaries are large, and enter a notch between 

 the vertical and occipitals. Occipitals extremely large. Seventh 

 upper labial very long. The labials, additional oculars, and 

 peculiar gular shields as in the adult. Anal entire. Subcaudala 

 divided. 



Colour rich reddish brown. Body with somewhat reticulated 

 bars, formed by some of the scales being particoloured, white in 

 front, and deep claret-coloured behind, giving a half banded, half 

 spotted appearance to the snake. A conspicuous white collar on the 

 nape, mottled with claret-red. Belly brown, spotted and mottled. 

 Three young specimens are in the Museum of the Asiatic Society 

 of Bengal, presented by Major Berdmore, from Martaban. 



This is a very singular snake, the young differing so much from 

 the adult as to lead Mr. Blytli to refer these to different genera. 

 As, however, the adult has divided suhcaudals, but one loreal, and 

 fifteen rows of scales, it is certainly not Aplopeltitra boa, Schl., 

 but the adult of P. macularius, Blyth, I think it open to question 

 if all the specimens do not come from the same locality, as it is 

 strange the young and old should come from different localities ; 

 and a mistake is very likely to have occurred, as Major Berdmore 

 collected largely in both localities.
