Order IV. COLUMBiE * 
is composed of those birds only which are well known under the denomination of Pigeons, and, as it 
embraces but one family, the characters will be given under it. 
The Family 
COLUMBIDjE, or Pigeons, 
have the Bill short, straight, compressed, with the apical half of the mandibles more or less vaulted and 
strong, and the base more or less weak, and covered by a soft fleshy membrane, in which are placed the 
Nostrils ; the Wings moderate ; the Tarsi more or less long and robust ; and the Toes lengthened, 
divided, and padded beneath. 
The first Subfamily, 
TRERONINjE, or Tree Pigeons, 
have the Bill short, with the ends of both mandibles vaulted, and of nearly equal thickness ; the Tarsi 
very short, and more or less feathered ; the Toes divided at the base, the inner much shorter than the 
outer 5 and the claws short and curved. 
Ptilonopus Swains .f 
Bill short, slender, with the tips of both mandibles of nearly equal thickness ; and the nostrils linear 
and lateral. ’ Wings moderate, with the first quill shorter than the second, the end generally narrowed 
for some distance from the tips, and the third the longest. Tail moderate and even. Tarsi short, and 
feathered to the toes. Toes free at their base, and padded beneath ; the inner toe shorter than the outer ; 
the claws short and much curved. 
These showy birds are found principally in Malacca, Celebes, the north-west coast of Australia, and the islands of 
the Pacific Ocean. Their habits are peculiarly arboreal and solitary, living entirely in the deep forests, where they 
are only discovered by their incessant and loud cooing. The fruits of various trees form their food, especially that of 
the banyan, &c.
