Ramphastos oscidans. Gould, Proceedings of Zool. Soc., Part III. 
We find in this interesting species of Toucan a union of the peculiar characters of several other species, for 
vs'hich reason I have given it the specific appellative of oscidans. The bill and upper tail-coverts resemble 
those parts of Rampli. culminatiis and Ramph. Cumeri ; the breast is like that of Rarnpli. Vitellinus ; and 
in the narrow scarlet band on the chest, it bears an affinity to Ramph. Sivamsonii. 
The great variety of colouring which ornaments this new species rendei's it one of the most pleasing and 
elegant of the genus : in size it approximates to Ramph. Vitellinus and Ramph. Ariel. 
I am indebted for this fine bird, as also for others, to the treasures of the Vienna collection, which contains 
two specimens, one fully adidt, and another, although in size nearly equal to its companion, evidently a young 
bird, as was most clearly proved by the undeveloped state of the beak. 
The country whence these valuable specimens were brought is stated to be Brazil, but from what particular 
district I was unable to ascertain.
