 conotus), is common in the interior and much prized as a cage 

 bird both for plumage and song."

In this genus the wing and tail are almost equal in length. 

 The velvet-like feathers at the base of the forehead are present. 

 The bill is proportionately short and sharply pointed ; its width 

 and depth at the base are equal to about half the length of the 

 exposed culmen. The wing is rounded, the third and fourth 

 primaries longest, the second about equal to the fifth, and the 

 first intermediate in length between the seventh and eighth. 

 The tail is rounded at the tip, the outer feather on each side 

 is nearly one-third shorter than the middle ones. The tarsus 

 exceeds the length of the exposed culmen by about one-third. 

 Coloration : male and female alike.
