BIEDS FROM NORTH CELEBES RILEY.

Hartert *^ has fixed the type locality of Viellot's Por'pliyr'io calvus as 

 Java, as was previously done by Meyer and Wiglesworth."*^ The 

 latter authors at the place cited also say that individuals of this 

 species differ in the two ends of the island of Celebes, but on this 

 point my lack of material will not allow me to venture an opinion. 

 I am using ■** the oldest name founded upon a Celebes specimen, 

 since it would be unwise to lump it with the Javan bird, especially 

 as Sharpe*® has pointed out that the birds from south Celebes are 

 not the same as those from Java, but this author further says that, 

 some specimens from north Celebes appear to be the same as those 

 from Java, while others from the same end of Celebes he refers t@ 

 Porphyrio smaragdiwus! The truth of the matter seems to be that 

 the genus is badly in need of revision, "with ample material, and 

 that any identifications founded upon our present knowledge of the 

 forms are merely tentative.
