like, or scrub-covered lowlands of Cambodia and Cochin-China 
bordering the lower course of the Mekong River; the barren 
Korat Plateau of Eastern Siam drained through the Nam Si 
River to the Mekong River; central Siam, watered by the 
Menam Chao Praya; peninsular Siam together with Tenas- 
serim, forming the upper part of the Malay Peninsula ; the lower 
Malay Peninsula (excluding the hill country of Perak) ; the 
rainy Salween and Irrawaddy delta country; and finally the 
"dry zone" of central Burma. 
Characteristic mammals of the Malayan tropics include the 
Moonrat (E chinos or ex), some White-toothed Shrews (Suncus 
and Crocidura) , most of the Fruit Bats, and among insectiv- 
orous Bats many Pipistrellus, Disk- footed Bats, and other 
Vespertilionid Bats of the genera Hesperoptenus, Eptesicus, 
Scotophilus, and Kerivoula; most of the Free-tailed Bats and 
many species of Rhinolophus and Hipposideros, also the Hairy- 
faced Horseshoe Bats Coelops. Other representative mammals 
are Pangolins, Flying Lemur, Langur Monkeys, Macaques and 
Gibbons, tropical Weasels and Otters, Malay Bear, Banded Lin- 
sang, most of the species of Civets and Mongooses, several Cats, 
certain Hares, the Giant Squirrels, many groups of Tree Squir- 
rels, the Sunda Long-nosed Squirrel, the Black Flying Squirrel, 
and several Dwarf Flying Squirrels. In addition, there are 
several genera of Mice with the great toes of the hind feet 
opposable, a wealth of the species groups of Rattiis, Long-tailed 
Porcupines, the Elephant, the Crested, Banded, and Bearded 
Pigs, Mouse Deer, Wild Cattle, Muntjaks, Hog Deer, Sambar 
Deer, Eld's and Schomburgk's Deer, Tapir, and Rhinoceros. 
An Ancient East Asian Faunal Area. There is, further, 
a pattern of distribution in southeastern Asia that disregards 
and transgresses many of the faunal areas just described. No 
less than sixty-seven thoroughly distinct species groups of the 
mammals dealt with in this work have distribution patterns that 
run to a greater or less extent from the general Burma- South
