I FIRST became acquainted with this Jacamar in 1854, from examples contained in the collection 

 of the late Professor Behn, of Kiel, which had been obtained by that naturalist during his 

 travels in the Brazilian province of Goyaz, and described it shortly in my " Remarks on the 

 Jacamars " published in the Zoological Society's ' Proceedings ' for 1855. At the same time I 

 remarked that I had seen in the Museum of the Jardin des Plantes at Paris a specimen brought 

 by d'Orbigny from Guarayos, in Bolivia, which I was also inclined to refer to the same species, 

 although I had previously alluded to it as a variety of Brachygalha lugubris. 



Since 1865 I have had further opportunities of examining the above-mentioned specimen of 

 d'Orbigny, and have convinced myself that it really belongs to the present species. There is 

 also in the same collection the typical example of " Galhula albiventris, Cuv.," as described by 

 Lesson in his 'Traite d'Ornithologie.' This bird, I find, which was obtained by Auguste 

 St.-Hilaire in the Brazilian province of Goyaz, also belongs undoubtedly to Brachygalha melano- 

 sterna. But the name albiventris, although given before melanosterna, cannot be used for the 

 present species, as it was originally applied by Cuvier not to the specimen described under that 

 name by Lesson, but to Levaillant's '•^Jacamar a ventre blanc," i. e. to Galhula leucogastra. 



Besides d'Orbigny and St.-Hilaire, a third well-known South-American explorer has met
