The Two-horned Rhinoceros occurs in Siam but is rather rare, 
though found in suitable localities throughout South-western, and 
Northern Siam and Laos.

Rhinoceros sumatrensis, Cuvier, Regne Animal 1, 1817, p. 240 
(Sumatra). 
The One-horned Rhinoceros also inhabits Siam where it is 
sparingly found along the Western frontier, but its distribution is still 
very imperfectly known like that of the former species. It seems, how- 
ever, to be more common in the southern districts than in the north.

Tupirus indicus, Desmarest, Nouy. Diet. Hist, Nat. XXXL 1819, 
p. 408 (Malay Peninsula). 
The distribution of the Tapir in Siam is very imperfectly known, 
but it seems to occur in Peninsular and South-western Siam, at 
least north to the Province of Ratburi. According to Pousarges 
it also inhabit South-eastern Siam. Said to be fairly common in Patani, 
and recorded from Hat Sanuk and Hue Sai near the Siam-Tenasserim 
frontier.

The Malayan Maned Pig, which is very common in the Malay 
Peninsula, and especially in the southern parts, also seems to occur in 
Siam, but as very few specimens have been collected, its distribution 
towards the north is quite uncertain. It seems, however, to be fairly 
common in Peninsular and South-western Siam. Wild Pigs also occur 
in the northern districts, bat whether they belong to this or another 
allied race is unknown. Also recorded frum the Island of Koh Chang.
