VISCOUNT WALDEN ON THE BIEDS OE CELEBES. 75 



Ornithologicus' Corvus caledonicus. Thus there became a Corvus caledonicus, Gm., and 

 a Corvus caledonicus, Lath., the first being a Graucalus, the last a Streptocitta, the first 

 being a really New-Caledonian species, the last being only found in Celebes. In 

 1850 Bonaparte founded his genus Gazzola, making C. caledonicus, Gm., the type, and 

 associating with it the correct synonyms of true C. caledonicus, Gm. Still it is evident 

 that Bonaparte was confounding the then unique specimen in the Paris Museum of 

 the Celebean black-and-white Crow (which was labelled " Corvus dauricus de la Nou- 

 velle Cale"donie") with Corvus caledonicus, Lath., the black-and-white Streptoritta; for 

 the Prince would never have identified a true Graucalus with either a Pica or a Corvus, 

 and he made Gazzola the connecting link between the Garrulidee and the Corvidse. 

 Thus the elements of confusion were these : — one Corvus caledonicus, Gm. ; two species 

 under that title in Latham, one of them being described as black and white ; a black- 

 and-white Corvus in the Paris Museum labelled " C. dauricus de la Nouvelle Caledonie," — 

 only one of the three species being a New-Caledonian bird. Three years later Bona- 

 parte partly cleared up the confusion. He (Notes Ornith. I. c.) changed the title from 

 Gazzola caledonica (Gm.) to that of Gazzola typica, Bp., on the ground that the type of 

 his genus Gazzola was neither of the " deux C. caledonicus, de Latham," 1 nor that of 

 Labillardiere, nor that of Gmelin. The question now arises whether Corvus caledonicus, 

 Gm., ought to be considered the type of the genus Gazzola. It has been so treated by 

 Mr. G. R. Gray (Hand-list, no. 1246). But as the Prince has described the species he 

 founded the genus on, I have thought it best to retain Gazzola for that species, which 

 is the same as Corvus advena, Schlegel. 



MM. Verreaux and O. des Murs (Rev. & Mag. Zool. 1860, p. 432) included Gazzola 

 typica, Bp., in their list of New-Caledonian birds, trusting, in all probability, to the 

 erroneous locality on the label of the Paris-Museum specimen.

Although Labillardiere (I. c.) tells us, very circumstantially, the date and the occasion 

 when and where he obtained his Pie de la Nouvelle Caledonie, Mr. Sclater's explanation 



1 This is a good illustration of the confusion that may be created by not quoting the names of the original 

 authors, or by replacing them with the names of subsequent authors, who may have quoted or misquoted.
