PERISTERIN/E 193 



This group is distinguished by a longer bill, very 

 faintly emarginate, and by its tarsi, which are mode- 

 rately long and naked, 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 indistinct 

 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 super ciliosis of Wagler may be taken as 

 the type.
