THE MAMMALS AT PRESENT KNOWN TO INHABIT SIAM. 173 
Very little is known at the present time about the distribu- 
tion and occurrence of Schomburgk’s Deer in Siam. Probably found in 
Central Siam on the great swampy plains around Paknam Po and_pos- 
sibly in Muang Petchabun.

Hyelaphus annamiticus, Heude. Mém. Hist. Nat. Emp. Chinois IT, 
1888. p. 50. (Annan). 
Hog-Deer are said to be quite common on the grassy plains in 
the Province of Chantaboon, South-eastern Siam. Also observed by the 
present author at Nong Bea in North-western Siam, but whether the 
northern specimens belong to this or an allied race is still unknown, as 
no specimens have been collected and properly examined. 
295. CAPRICORNIS SUMATRENSIS MILNE-EDWARDSI David. 
Capricernis milne-edwardsi’, David. Areh. Mus. Paris. V. 1869. p, 10. 
(Moupin, Szechuan, China). 
Fairly rare though occurring among the mountain regions of Nor- 
thern and probably South-western and Western Siam. As no Siamese 
specimens have been properly examined up to the present time it seems 
impossible to ascertain if the Goat Antelopes found in Siam are identi- 
eal with the Chinese form or not. 
296. CAPRICORNIS SUMATRENSIS SWETTENHAMEI (Butler). 
Nemorhoedus swettenhamei, Butler. P. Z, S. 1900. p. 675. (Larut Hills, 
Perak, S. Malay Peninsula). 
Even of this form very little is known at the present time, but it 
probably inhabits Peninsular and possibly South-western Siam.  Re- 
corded from Jalor and Patani by Bonhote. The specimens obtained at 
Koh Lak probably belong to this form. 
297. Bos BUBALIS Linn. 
Bos bubalis, Linnaeus. Syst, Nat, Ed, 10. 1758. p. 72, (India). 
Some herds of semi-domesticated Water Buffaloes occur in 
Siam, where they have been recorded from Muang Pimai in Eastern, 
from Pailin in South-eastern, from Sam Roi Yot in South-western, and 
from the neighbourhood of Raheng in Central, Siam, but really wild 
Water Buffaloes do not occur in the country.
