Family II]. Cotumpipa. PiGeons. 
This family includes all the remaining species of the Order. Of the 
Ground Pigeons exhibited we may specially mention the Giant Crowned 
Pigeons (Goura) (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 (Calenas nicobarica) (213) 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 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 
(Chaleophaps indica) (221), and the diminutive Long-tailed African Dove 
(ina 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. turtwr) (231) may be specially 
meutioned, and of the latter the Stock- Dove (237), the Rock-Dove (238), 
and the Wood-Pigeon (239), 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 ( Ectopistes 
migratorius) (241), of Eastern North America, complete the more 
noticeable species in this Case. The latter species is now almost 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 
*voost ” 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, 
Lopholenus 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 (Pti/opus jambu) (271) from 
Borneo. The Red-crowned Pigeon (Alectrwnas pulcherrima) (261) 
from the Seychelles represents a remarkable little group, one of which,
