the female being baiTcd with I'utbus. The (iuans [OrtuVis) (53-55), of 

 vvliich three species arc slio\yUj ai'c very similar birds to the two former, 

 but tlierc is a thin band of featliers down the middle of the naked 

 throat, and no wattle. The remaining three genera, Pipile (56), 

 Alinrria (57), and CltaiiHepL'tts (58, 59), are remarkable in having the 

 inner web of tlie first two or three Hight-feathcrs deeply excised. 



Suborder II. A l k i t o k (j r o d k s. Tkue Game-Bikds. 



This grou[) includes the Pheasants, Partridges, and Grouse, whicli 

 normally nest on the ground. They arc characterised by having the 

 hind toe {hallux) raised above the level of the other toes, and by having 

 the inner notch of the breast-bone istcnimn) more than half the length 

 of the entire stci'uum. 



Family I. Piiasianid.e. Pheasants, Partridges, and Quails. 



The large number of Ganic-Birds comprising this family are 

 distinguished from the Grouse by the following characters. The 

 nostrils are never hidden by feathers, and the legs are either feathered 

 partially as in the Snow-Partridges (Lenra) ( 1 64) or wholly naked and often 

 armed with one or more pairs of spurs. The toes are always devoid of 

 feathers and never pectinate along tiie sides, the horny comb-like 

 appendages so characteristic of the Bare-toed Grouse being invariably 

 absent. 



This great family has been divided into the subfamilies Odonto- 

 phorliiu', Pfiuxianiiue, and Perdicniie, the first containing the American 

 Partridges and Uuails, the second the Pheasants and Peacocks with 

 their allies tlie Turkeys and Gruinca-Fowls, and the third the Old- 

 VVorlcl Partridge like forms. 



Subfamily I. Odoiitoplioruuc American Partridges and Quails. 



The American Partridges (Odonto/jfiorhire) are distinguished by [Case 0.1 

 Laving the cutting-edge of the lower mandible serrated or provided 

 with a tooth-like process, well marked in the great majority of species, 

 but in some instances less distinct. 



The Scaly Partridge [Callipepla sijuamata) (60) is a native of the high 

 barren plateaus of ^Mexico and the States immediately to the north. 

 In both sexes the black edges to the feathers give the phimage a scaled 

 appearance. 



Of the Crested Quails {Eupsychortyx) eight small species arc known 

 to inhabit Central America and the north-east of South America. An 

 example of this groui) may be seen in the While-faced Crcstcd-Quiiil 

 {E. Ieucopo(joii) (62).
