PLATE XXXIV. 



Trochilus latipennis, Broad-shafted Humming-bird, Swainson^ 

 Zoological Illustrations^ first series, plate cvii. Oiseau-mouche 

 latipenne, (Campylopterus latipennis, Sw.) Lesson, Histoire 

 Naturelle des Oiseatuc-mouches, pi. xxxv. p. 124. 



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.
