176 ON THE BIRDS OF CELEBES. [1872. 



and-white Streptocitta ; for the Prince would never have identified a true Graitcahis with either 

 a Pica or a Corcus, and he made Gazzola the connecting link between the Garrulidic and the 

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

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

 white Conns in the Paris Museum labelled " C. daurieiis de la Nouvelle Caledonie," — only one 

 of the three species being a New-Caledonian bird. Three years later Bonaparte partly cleared 

 up the confusion. He (Notes Ornith. /. 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 " *, 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. 12-10). 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. et Mag. Zool. 1860, p. 432) included Gazzola typica, 

 Bp., in their list of New-Caledoniun 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 

 Tr.Z.S.viii. and where he obtained his Pie de la Nouvelle Caledonie, Mr. Sclater's explanation (i'. c.) of the 

 p. 70. probable cause of the error is most likely correct. Yet it must be borne in mind that 

 Labillardiere never set foot on the island of Celebes proper ; nor does Entrecasteaux's expedition 

 appear to have had any direct communication with that island on either of the occasions of its 

 presence in the Moluccas. On its vay from Bouru to Sourabaya, in October 1793, the 

 expedition, after failing in its attempt to pass the Straits of Tioro, occupied several days in 

 passing tho.se of Boeton, and remained a day at the town of Boeton itself. During this period 

 the French naturalist made several excursions on shore, and, as he particularly mentions, in the 

 island of Pangasane, and one, of two hours' duration, in the neighbourhood of the tovra of 

 Boeton. It is most probable therefoi'e that this form of Streptocitta was obtained either on the 

 island of Pangasane or of Boeton ; for the expedition did not touch the mainland of Celebes, 

 nor at the island of Saleyer when passing the straits of that name. 



* 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 iiuotcd or misquoted.
