Wliile doubtful whether the bird whose characters are given above is the true 

 S. iodura, which, judging from the colored figures on which the name is based and 

 descriptions by authors, seems more like S. viridigaster, I nevertheless feel sure that 

 it can not represent an extreme variation of the latter, being much too different in 

 coloration of the tail. I have seen but one specimen, a "Bogota" skin, in the collec- 

 tion of the U. S. National Museum.
