AN examination of the Prince of Massena’s collection at Paris in 1843 afforded me an opportunity of giving
a description of a species of Toucan I had never before seen. The only information I could obtain respect-
ing this new bird, of which His Highness possessed a male and a female, was that it had been received in
a collection from Santa Fé de Bogota in Columbia. In the interval that has since elapsed, the Prince’s fine
collection has been transported to North America, and now finds a resting-place in the extensive Museum
of the Academy of Sciences at Philadelphia. Being desirous of instituting a more rigid examination of the
species, and a more careful comparison of it with the allied members of the family than I was enabled to
do when it first came under my notice, I applied to T. B. Wilson, Esq. of Philadelphia for another sight
of it, and he has, with the utmost liberality, allowed it again to cross the Atlantic for this purpose. Ou
re-inspecting it, I find that the conclusion I originally came to, as to its being a distinct species, is quite
correct. It belongs to that section of the family, members of which are distinguished by broad culmenal
marks, a feature more conspicuous in this than in any other species, the greenish yellow colour not being
confined to the culmen alone, but occupying a considerable portion of the sides of the upper mandible also :
the lower part of the breast is fine sulphur-yellow, passing into white on the throat and sides of the neck ;
the rump is fine sulphur-yellow, instead of passing into orange, as in R. Cuvieri, R. CUTE aia, and R. oscu-
lans ; the bill is thick and swollen, as in the latter ; but it is shorter, and on comparison will be found to

present a different aspect.
The figures are of the natural size.
