Ornithologists of the present day are induced to consider the bird here figured as referrible to the 
Ramphastos dicolorus of Linnaeus; and without venturing to question the accuracy of this opinion, it must 
nevertheless be observed that the specific term is somewhat inapplicable to a bird possessing three decided 
and conspicuous colours. This species has been illustrated by Sir W. Jardine and Mr. Selby, in their valuable 
‘Tllustrations of Ornithology,” as a typical example of the true Toucans; in which publication will also be 
found a somewhat lengthened description, as well as an account of the general habits and manners, of the 
species comprising this family. 
The Ramphastos dicolorus may be readily distinguished from all other species by several prominent characters. 
It is the smallest of the genus, and in the colour and development of the bill much variety exists. 
To the want of opportunity of examining a series of specimens at one time may be attributed the confusion 
in the nomenclature with respect to this bird. I am fully persuaded, however, that these changes are entirely 
attendant on age, sex, or season. The females have always the shorter bill and rather less brilliant colouring, 
offering also in stature the same disproportion, independent of which no other external differences are to be 
discovered, and these even are so trifling as scarcely to indicate the female without actual dissection. 
The young bird, which is represented in the lower figure, is barely arrived at that period at which it is 
capable of providing for its own wants; the bill at this age is extremely delicate in texture, and is so soft and 
yielding as to require food of the most pulpy and nutritious nature, in all probability fruits, larvie of insects, &c. 
Even at this youthful stage the plumage has assumed its perfect colouring, and the tints are scarcely less 
brilliant than those of the adult: in this particular the family of Ramphastidce closely resemble tlie Fissirostral 
birds, and like them lay white eggs, and incubate in holes or dark recesses. 
The present species is extensively spread over the Brazils. It has been received from Rio de Janeiro, 
Bahia, and Paraguay.
