96 DISTRIBUTION OF ANIMALS. [PART 1. 
The Psittaci or parrot tribe are still in a very unsettled state 
of classification ; that recently proposed by Professor Garrod 
differing widely from the arrangement adopted in Dr. Finsch’s 
monograph of the order. Taking advantage of the researches 
of these and other authors, the following families are adopted as 
the most convenient in the present state of our knowledge: 
76. Cacatuide ... ... The Cockatoos. 
77. Platycercidze ... The Broad-tailed Paroquets of Australia. 
78. Palzornithide ... The Oriental Parrots and Paroquets. 
79. Trichoglosside .... The Brush-tongued Paroquets and Lories. 
80. Conuride ... ... The Macaws and their allies. 
81. Psittacide ... ... The African and South American Parrots. 
82. Nestoride ... ... The Nestors of New Zealand. 
83. Stringopidee .... The Owl-parrots of New Zealand. 
The Columb, or pigeons, are also in a very unsatisfactory 
state as regards a natural classification. The families, sub- 
families, and genera proposed by various authors are very 
numerous, and often quite irreconcilable. I therefore adopt 
only two families; and generally follow Mr. G. R. Gray’s hand- 
list for the genera, except where trustworthy authorities exist 
for a different arrangement. The families are : 
84. Columbide ... Pigeons and Doves. 
85..Didide ..... ... The extinct Dodo and allies. 
The Galline, or game-birds, may be divided into seven 
families : 
Fam. Sub-fam. 
86. Pteroclide  ... = mee ... Sand-grouse. 
87. Tetraonide ... Sie eae ... Partridges and Grouse. 
Pavonine ... .-. Peafowl. 
Lophophorinz ... Tragopans, &c. 
Phasianine ... ... Pheasants. 
88. Phasianide ... | Euplocamine .... Fire-backed Pheasants, &c, 
Galline _... ... Jungle-fowl. 
Meleagrine... .-- Turkeys. 
Numidine ... ... Guinea-fowl. 
89. Turnicide A ee aot ... Hemipodes. 
90. Megapodiide ... ; aa ... Mound-makers. 
Cracine .... ... Curassows. 
91. Cracide —...+ Penelopine... ... Guans. 
Oreophasinz .... Mountain-pheasant. 
92. Tinamide nae ie. Pre .... Tinamous.
