472 Mr. Vigors's Sketches in Ornithology/. 



[Vol. iv. pi. 32. f. 1.], and still retaining his reference io Mr. 

 Edwards's figure. There are evidently two birds included in 

 this last description. For M. Brisson's figure not only differs 

 from that of Mr. Edwards's bird, but the difference is pointed 

 out by the latter bird being also accurately figured and described 

 as a distinct species in the '' Ornithologie," [Vol. iv. p. 416. pi. 31. 

 f. 2.] under the appellation of Tucana Cayennensis gutture albo, 

 Linnaeus, in describing them under one name, probably considered 

 them as the sexes of the same species. 



Of the two birds thus included by Linna?us in his description 

 of JR. tucanus^ the first ought properly to be considered the 

 original type of that species. But as that bird has long been 

 known under the name of R, erythrorhynchus^ Gmel., and as it 

 is a very common species in our collections, much confusion might 

 arise by altering the name under which it has so long been dis- 

 tinguished. The second bird therefore to which Linnaeus refers 

 in his last edition, may be chosen as the representative of the true 

 tucanus of that authour. 



I have never seen an individual that exactly accorded with 

 Linnaeus's specifick characters of this bird, as amended in his last 

 edition. The existence however of the species has been placed 

 beyond doubt by M. Le Vaillant, who obtained two specimens of 

 it at Lisbon, which had been brought from the New World, and 

 which he figured and described in his work * on these birds [pi. 4.] 

 One of these specimens he retained in his own cabinet : the other 

 he transferred to the collection of M. Raye of Amsterdam. His 

 description and figure intimately accord with Linnaeus's descrip- 

 tion of the species : the yellow pectoral band, and the under and 

 upper tail coverts of the same colour, answering to the '^fascia 

 abdominali crisso uropygioque Jlavis " of the " Systema Naturae." 

 The bill also generally corresponds with Linnaeus's description 

 of that member. M. Brisson's figure and description, to which 

 Linnaeus referred, do not so closely accord with the same 



* M. Le Vaillant hesitates in referring his bird to R. tucanus Linn., in 

 consequence of its not agreeing with Mr. Edwards's figure, in his 329th plate. 

 But Linnaeus himself did not refer to that figure for his tucanus : it was Gmelin, 

 as has been before observsd, who erroneously introduced that reference.
