Localities. This Green Viper is the poisonous snake most often 

 seen about Bangkok, where it is fairly numerous ; about ten indi- 

 viduals were caught in my garden alone in about twelve months. 

 The British Museum Catalogue mentions specimens obtained at 

 Pachebone and in the Laos Mountains by M. Mouhot. It is ap- 

 parently the commonest Lachesis in Penang (Cantor, Stoliczka, 

 Van Sommeren, and S. S. P. [at 2000 ft. elevation]) and Proviuce 

 Wellesley (Stoliczka and S. S. P.), but at Siugapore (from which 

 place it is recorded by Cantor, Blanford, and Hanitseh) it is rare, 

 its place being taken by L. ivagleri.
