Cochinchina,’ Lond. 1828, 4to.) observes, pp. 434, 435, that Tor- 
toises and Crocodiles are not so frequent in the Menam as in the 
Ganges, that Lizards and Snakes are very numerous: “some were 
obtained even in the court-yard of our dwelling ; among those we 
found no poisonous ones. The Hooded-snake, Coluber naja, is known 
to exist; also a Python 12-13 feet long.” 
From notices made by Sir J. Bowring in ‘The Kingdom and 
People of Siam,’ Lond. 1857, 8vo., vol. i., it is evident that there is 
yet a wide field for the Herpetologist in Siam. P. 228, “‘ The reptiles 
of Siam are multitudinous; Crocodiles live in the rivers from their 
mouths to their shallows.”’ P.230, ‘There are many species of lizards; 
the largest is the Tackuet, the tongue of which is divided in two ; 
the noisy Tookay, destroying vermin ; Chameleons, Flying-lizards ; 
Serpents from the most gigantic to the smallest species.”” P. 231, “a 
snake called ‘Sun-beam’ from its very brilliant colours, inert, the 
bite of which is said to be mortal ; an immense frog sings, especially 
during rain.” 
We see from the notes quoted that we can add to the above list 
some other reptiles: those specifically determined are Naja tripu- 
dians and Crocodilus galeatus, those generically, Chameleo and Draco, 
the Tortoises being mentioned in too general terms to admit of any 
further suggestion.
