THE GENUS PIONUS. 9 



Nor, SO far as I am aware, have any specimens been more recently obtained 

 until Mr. Buckley's expedition into Bolivia in 1875, when, along with many 

 other new and interesting birds *, several new examples of this species were 

 procured. From one of these, now in my collection, the accompanying figure 

 has been prepared by Mr. Smit. A glance at it will be sufficient to show 

 how distinct P. tumidtuosus is from every other known species of the genus. 

 It belongs to the green- winged section of the group, and may be most conve- 

 niently placed next to P. seniloides ; but it is immediately distinguishable 

 from this and every other known species of the genus by its rosy-red head. 

 This colour pervades also the sides of the face and throat, but is there varied 

 by purplish margins to many of the feathers. As regards size there is 

 apparently little difference between the two species.
