In the first edition of this Monograph, I remarked, that “ although I have at all times endeavoured to avoid 
imposing a specific title on a new species, which did not convey some idea connected with its form and 
colouring, I have been induced to deviate from this rule in the present instance, from an earnest desire to pay 
a just tribute of respect to a most able naturalist, through whose personal exertions in the Brazilian forests 
for the long period of eighteen years, a vast collection has been transmitted to Vienna, the capital of that 
country by the munificence of whose government he was enabled to prosecute his researches.” Shortly 
after this paragraph was written, myself and every lover of natural history had to lament the loss of this 
ornament to science; I, however, had the satisfaction of knowing that I had perpetuated the name of my 
friend by naming this species after him. At that time the specimens in the Imperial Museum, from which 
my figures were taken, were the only examples in Europe; in the interval which has elapsed, many others 
have come under my notice: I believe M. Natterer’s specimens were collected on the Rio Madeira; Sir 
Robert Schomburgk brought numerous examples from the far interior of British Guiana; and Mr. Wallace 
observed it on the Upper Rio Negro; consequently the forests bordering the tributaries of the Upper 
Amazon, towards the Andes, may be considered the habitat of this fine species. 
At present nothing whatever is known as to its habits and economy. 
The Plate represents the two sexes of the natural size.
