We are indebted to Mr Swainson for permission 
to copy his beautiful plate of this singular bird ; and 
since the figure was completed, we have fortunately, 
by the attention of Mr Kirk, received two perfect 
specimens of the bird itself from the island of Tobago, 
which have served for the following description. We 
may remark, that Mr Swainson’s specimen was pur- 
chased at Bullock’s sale, and that he considered the 
specimen unique; and when Lesson published his 
Monograph, in 1829, no specimen existed in the 
Paris collections. 
The Tobago specimens are about five inches and 
a quarter in length. On the throat is a patch of the 
clearest violet-blue, shading off to steel-blue on the 
This plate is slightly reduced from the original.
