PERISTERIN^.

This group is distinguished by a longer bill, very 
faintly etnarginate, and by its tarsi, which are mode- 
rately long and nake<l, with the frontal scales divided 
into two series, and the sides and hinder part reticu- 
lated with minute scales. Another group seems in- 
dicated by certain Asiatic species, conspicuous for 
the rich metallic green of their dorsal plumage, simi- 
lar to that of some of the Ptilinopinse. These have 
the tarsi destitute of scales, except a few in<listinct 
ones in front, just above the junction of the toes 
Their bill rather long, and destitute of the notch. 
They live mostly upon the ground, but possess con- 
siderable powers of flight. Of this latter group the 
Columba superciliosis of Wagler may be taken as 
the type.
