Boliophis intestinalis, Blgr. Cat. Snakes, iii. p. 401. 



Of the Malay poisonous snakes this is perhaps the most fre- 

 quently met with. I have come across it both in bright daylight 

 and after dark, crawling slowly about ; it is easily caught. What 

 the effect of its poison on a man would be is, I believe, quite un- 

 known ; but from its small mouth and want of activity it can 

 hardly be looked on as a dangerous species. Cantor found that 

 fowls bitten by this snake died from within an hour and twenty 

 minutes to upwards of three hours. " The serpents, which all had 

 forcibly to be made to inflict the wounds, shortly afterwards 

 expired, apparently from the violence to which they had been sub- 

 jected."

 with a narrow scarlet black-edged vertebral line ; along each side 

 a pale yellow line, above broadly edged with black, below edged 

 with black spots on a somewhat vandyked dark-brown line. Under- 

 neath pale yellow, with black cross-bars generally about half the 

 width of the yellow interspaces. Upper surface of head may be 

 dull vermilion. Labials yellow, spotted with black. Under surface 

 of tail bright coral-red, with three black cross-bars.

Haplopeltura boa, Blgr. Cat. Snakes, iii. p. 439. 



Cantor obtained two individuals from the Penang Hills, and 



recently Mr. A. G. B. van Sommeren found two at the same time in 



holes in the ground on Government Hill, Penang, at 2500 feet 



elevation. The snakes of this family are apparently very rare in 



he Straits Settlements ; with the above exceptions, they are not
