96 Mammals of Eastern Asia 
Most of the foregoing Bats are colored gray-brown or ashy- 
brown. The large malayana is the peninsular representative of 
K. papulosa of Java. It has been recorded from Tonkin and 
probably occurs in the intervening territories. The bright 
orange-brown body fur, and wings variegated with gray and 
orange, makes picta, found from Moluccas to Malaya and Siam, 
and its close relative bellissima of Hainan the most conspicuous 
Bat of the genus. 
The great student of Bats, Mr. G. E. Dobson, believed that 
the peculiar color patterns of the wings of K. picta and of the 
myotine subgenus Chrysopteron were explained by "protective 
mimicry/' their resemblance to brightly colored decaying leaves 
affording them concealment. 
THE MASTIFF OR BULLDOG BATS (FAMILY MOLbSSID^E) 
In many ways this is one of the most peculiar of the families 
of Bats. The common name implies a fancied resemblance to 
bulldogs. The head is broad, short, and rounded; and in some 
genera the ears are large, thick, ribbed or folded, and lie almost 
in a plane with the animal's direction of flight. In all but one 
genus the ears are united by a fleshy band across the forehead, 
but in ChcBromeles they are small, thickish, simple, and widely 
separated. The tails of the Molossid Bats are unique in that 
the terminal half extends free beyond the inter femoral mem- 
brane and this latter can be slid by muscles freely along the 
length of the tail to increase or decrease its area. The feet also 
are exceptional, being provided with thick, fleshy toes and stiff, 
fringing, spoon-shaped hairs. The wings are narrow, the wing- 
beat rapid. The species are apparently all insectivorous. The 
family inhabits the tropical parts of both hemispheres. 
The few eastern Asiatic members of the Molossidse include 
the large, extraordinarily ugly, almost naked Cheiromeles in 
which the ears are widely separate, and two or three weakly
