relatively stouter than in other species; but in coloration it is 

 remarkably like G. inornata, which in form of bill and other characters 

 is much Hke typical Clilorcenas. C. rufina is pecuhar in its much less 

 prominent nasal opercuh, shght anterior extension of frontal feather- 

 ing (the extremity of which is practically in vertical hne vnih the 

 point of the malar antia), and, apparently, want of small roundish 

 scales on the planta tarsi.
