In 1910 when discussin<]i: the relationship of the Formosan reptilian 

 fauna to that of the Philippine archipelago''^ I stated that there 

 ^Yere only two species common to Formosa and the Philippines which 

 had not 3^et been collected in Chinese territory, namely Dasia smarag- 

 dina^ a skink of wide distribution and likely to have been introduced 

 into Formosa by human agency, the other being the snake here under 

 consideration. With regard to P. jmlverulentus I then remarked 

 that its discovery within the limits of China would not cause sur- 

 prise as its known distribution includes Assam, Sikkim, and the 

 Shan states. This prophecy was fulfilled within four years, for in 

 1914 Mr. Stanley recorded specimens both from north and south 

 Fukien, and from Hainan. 



Further confirmation is had through a specimen (No. 65394) col- 

 lected by Mr. Sowerby near Yenpingfu, Fukien.

A specimen with a badly mutilated head, (no. 67815) was col- 

 lected by Mr. Graham 50 miles northwest of Kuanshien, Szechwan, 

 on the road to Sungpan, 1924. The scale formula is as follows'; 

 sc. 15; V. 176; a. 1; subc. 74. The head is so badly crushed that 

 the separate shields can not always be made out with certainty.
