1899.] REPTILES OP THE MALAY PENINSULA AND SlAAl. 665 



Dr. Haase's Bangkok specimens of "iy.jara" that I have examined 

 are undoubtedly L. aulicus.

123. Ltcodon subcinctus Boie. 



Lycodon platurinus. Cantor, p, 96. 



Lycodon subcinctus, Blgr. Cat. Snakes, i. p. 359. 



B-ecorded from Penang Hill (Cantor) and Singapore (Brit. Mus. 

 Cat., Hanitsch, Flower). In December 1896 I obtained another 

 specimen in Singapore, 710 mm. in total length. In September 

 1897 Dr. Wilson gave me a specimen caught in Johore Bahru. 

 And in April 1898 I got two males in the Larut Hills, Perak, at 

 an elevation of 4400 feet (each of which had a recently swallowed 

 lizard, Lygosoma sp. incert., in its stomach), one 753 mm. and the 

 other 756 mm. in length. 



Colour (in life). Above purplish black, with double white cross- 

 bands. Skin between scales whitish. Below, buff and purplish 

 black ; anteriorly the two colours fortn alternate broad but ill- 

 defined cross-bauds, posteriorly they are irregularly mottled. 



The similarity in colouring between this harmless snake and one 

 variety of the poisonous Bungarus candidus is worthy of notice.
