74 VISCOUNT "WALDEN ON THE BIRDS OP CELEBES. 



Were it not that Mr. Blyth had already remarked the imbrowned colouring of the head 

 and neck in examples from Celebes, contained in the Leyden Museum, I should have 

 felt less confidence in considerLag these Macassar individuals distinct from M. rvhro- 

 nigra, Hodgs.

The species inhabiting Celebes has not been satisfactorily identified. By Professor 

 Schlegel it is considered the same as that found in Java, while true C. validus, Temm., 

 Bp. (Consp. i. p. 385), is from Sumatra, and does not occur in Java.

Hob. Macassar {Wallace). 



This species has hitherto been found only in the Macassar district. Mr. Wallace {I. c.) 

 alludes to it as rare. It is an anomalous form, hardly exceeding a Lycos in size, but 

 with a bill equal to that of Corvus corone, and of much the same character. The 

 arrangement of the quills is peculiar. The fourth much exceeds the others; and the 

 first is very short. Prince Bonaparte separated it generically, but placed it next to 

 Corvus {Physocorax) moneduloides (Less.), another unique and aberrant Corvine form, 

 with which it has nothing in common beyond its general family relations. 



This species has partly been the subject of some of the most curious mistakes in 

 ornithological literature; and the position of the generic title Gazzola, Bp., whether 

 among the Campephagidse or the Corvidse, depends on a correct history and explanation 

 of how the confusion arose. In the thirteenth edition of the ' Systema,' Gmelin gave 

 the title of Corvus caledonicus to Latham's " New-Caledonian Crow," a species described 

 by Latham (General Syn. i. p. 377) from a drawing belonging to Sir Joseph Banks. 

 This is a true New-Caledonian Graucalus. In the second supplement to the ' SjTJopsis,' 

 Latham inserted a distinct bird (Labillardiere's "Pie de la NouveUe Caledonie") 

 under the title of " Caledonian Crow," and called it in the supplement to the ' Index
