8 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 60 



modification of the middle under tail coverts in the two genera, 

 present in both sexes and in the immature plumage appears to indi- 

 cate a close relationship. Unfortunately the only specimens of the 

 present species are two slightly immature males and an adult female, 

 so it is impossible to determine whether the outer primary of the 

 fully adult male is or is not modified near the tip. Goldman collected 

 the type of this new genus and species at Cana at an altitude of 2,000 

 feet in March, and during the same month and in May collected two 

 others on Mount Pirri at 4,500 and 5,000 feet altitude.
