An obscure species if really distinct from P. iolata. Mr. Elliot 

 possessed a second specimen precisely like the type, which he found 

 in a large trade collection sent from Bogota. He also obtained 

 another specimen of Petasophora with a fiery patch ou the throat, 

 but differing from P. coruscans. He described it as P. ruhrigularis 

 as follows : — 



" Upper and under surface shining grass-green, with a faint tinge 

 of blue in the centre of the abdomen. Line under the eye and ear- 

 coverts deep blue ; chin greenish blue ; throat metallic pink. Under 

 tail-coverts bright buff. Wings purplish brown. Tail light bronze- 

 green, with a subterminal blackish-brown bar. Bill and feet black. 

 Total length 4^ in. ; wing 2| in. ; tail 2 in. ; culmen | in."
