232 REMARKS ON THE ARRANGEMENT. 



should stand as the typical form, are at variance among 

 our ornithologists. Mr. Vigors, in his arrangement, 

 proposes the latter, Mr. Swanson Pavo, which for the 

 present we have adopted. Looking at the forms of 

 both, we find the tarsus and foot of nearly equal pro- 

 portional strength, the hallux articulated above the 

 plane of the foot, but in Pavo proportionably shorter, 

 and the nail short. In this form, also, flight, from the 

 unwieldiness of the plumage, is seldom resorted to, 

 except in extremities ; and the tail cannot be used in 

 directing it. In Phasianus flight is often resorted to, 

 and is powerful, though not capable of being long sus- 

 tained, and the tail is used in directing it : it therefore 

 deviates more from the peculiarities of the order. The 

 other forms are more difficult to fix. We are uncer- 

 tain, whether Euplocomus should not only form a 

 sub -genus of Lophophorus, and of the situation of 

 Tragopan. In both, the attributes of flight and perching 

 are more extensively used. Numida, again, seems to 

 connect the next family, by its alliance to the partridges, 

 in the form of the tail and feet, harsh cry, and general 

 habits. 



The more extensive examination of the whole order, 

 will, we trust, enable us, ere long, to solve all these 

 difficulties ; and we now prefer mentioning them as 

 they have occurred, to leaving them altogether un- 

 noticed.
