Description. 



Fourth quill longest ; third and fifth about equal ; second between fifth and sixth ; 

 first nearly equal to the eighth; entirely glossy black, witli violet reflections. 



In this species, the feathers of the head above and body are compact and blended ; 

 those of the back of the neck are very smooth and even, but do not show the out- 

 lines of each separately as elsewhere; on the chin and throat, the feathers are 

 elongated and lanceolate, each one more or less pendent or free, with the outlines 

 distinct to near the base; the bill is very long (three inches), and considerably 

 curved, the upper mandible extending considerably over the upper at the end.
