Family III. Cotumsipa. PuicEons. 
This family includes all the remaining species of the Order. Of the 
Ground-Pigeons exhibited we may specially mention the Giant Crowned 
Pigeons (Gouwra) (208, 209), the Grey-naped Ground-Pigeon (Otidiphaps 
cervicalis) (210) from New Guinea, held by some to be an ally of. 
Didunculus, the Nicobar Pigeon (Calwnas nicobarica) (243) with its 
remarkable metallic plumage and long neck-hackles, the Wonga-wonga 
(Leucosarcia picata) (214) from East Australia, and the beautiful 
Bartlett’s Blood-breasted Pigeon (Phlogwnas crinigera) (215) from the 
Philippines. In all these it will be noted that the length of the leg is 
very conspicuously greater than in the tree-haunting type of Pigeon. 
Above these will be seen the beautiful Bronze-winged Dove 
(Chalcophaps indica) (227), and the diminutive Long-tailed African Dove 
(Cina capensis) (228), one of the smallest of all the Pigeons. Next come 
the more familiar species belonging to the genera Turtur and Columba. 
Of the former the Turtle-Dove (7. turtur) (281) and the Eastern 
Turtle-Dove (Turtur orientalis) (231 a), which is included in the British 
List, may be specially mentioned, and of the latter the Stock-Dove (287), 
the Rock-Dove (288), and the Wood-Pigeon (289), all common species 
in the British Isles. The Rock-Dove is noteworthy, as from this 
species all the domesticated varieties have been derived. The handsome 
Reinwardt’s Cuckoo-Dove (Reinwardtenas reinwardti) (240) and the 
Passenger Pigeon (Hctopistes migratorius) (241), of Eastern North 
America, complete the more noticeable species in this Case. The latter 
species 1s now extinct, though only a few years ago it was met with in 
such countless flocks that a colony seen by the naturalist Wilson on 
one occasion was estimated to consist of more than 2,230 millions ! 
As late as 1878 a “roost” of these birds, at Petosky in Michigan, 
occupied an area twenty-eight miles long by three or four broad. During 
the nesting-season millions of birds are said to have been slaughtered 
without producing any appreciable reduction in their numbers. 
Resplendent colours are characteristic of the Fruit-Pigeons, though 
green may be said to be the predominant tone. Some, such as the 
Chatham Island form (Hemiphaga chathamensis) (249), exhibited on the 
floor of this Case, are of large size, and a curious crested species, 
Lopholemus antarcticus (248) from New South Wales, will be found 
near it. ‘The Nutmeg-Pigeon (Myristicivora bicolor) (250) from the 
Malay Archipelago is a striking form, being pure white with the flight- 
feathers and tip of the tail black. Among the more brilliantly coloured 
forms are the Orange Fruit-Pigeon (Chrysenas victor) (262) from the 
Fiji Islands, and the Jambu Fruit-Pigeon (Ptilopus jambu) (271) from 
Borneo. The Red-crowned Pigeon (Alectrenas puleherrima) (261) 
from the Seychelles represents a remarkable little group, one of which,
