This fine and rare species was discovered by Mr. Natterer, 

 and sent to Mr. Loddiges, in which collection it is still. It 

 was described by Bourcier, and dedicated to Mr. Schreibers, 

 Director of the Vienna Museum of Natural History, at that 

 time. It was a male specimen, not quite adult, without the 

 metallic feathers of the forehead. 



Many years after, Mr. Lawrence, of New York, received 

 some fine adult males, so different from the type, that he 

 described it again as I. frontalis^ but I am quite certain that 

 they all belong to one species. 



I have in my collection some very adult males, females, and 

 young, exactly like the type of /. schreibersi.

Habitat. — Peru. 



Mate. — Very closely allied to the preceding species. I 

 have examined Gould's types, one male adult and one male 

 junior, now in the British Museum, and the only difference 

 which I have been able to see between the two are the 

 following: — The lower part of the throat is not so purple, and 

 it has no golden-green band beneath it, that part is black. I 

 am not certain about the validity of this species. 



It was collected in Peru, by Mr. H. Whitely.
