LAMPORNIS. 3g 



median rectrices bronze-green, lateral ones steel-blue, glossed with green on the 

 outer webs, and tipped with white. 



Ohs. I have examined Mr. Gould's type of L. iridescens, and in my opinion the 

 difference in color that it exhibits is too slight and unimportant to entitle it to a 

 separate rank.
