This is a very rare bird in collections, very few specimens 

 havin^ as yet been obtained, but its habits, so far as they are 

 known, appear to be similar to those of its allies. The colora- 

 tion of the under-parts is peculiar, and very different from that 

 of any of the other species of this genus.
