The important paper mentioned last year (Zool. Bee. viii. p. 
41). Referring to the account of the characteristics of the island 
in Mr. Wallace's work (Zool. Rec. vi. p. 43) as rendering any 
further observations almost unnecessary, a tabular comparison 
of its genera with those of the Indian and Australian Regions is 
made, to determine the affinities of its avifauna. From thisQt 
appears that 37 Indian and 23 Australian genera occur there ; 
while 18 Celebean genera are common to both Regions ; 9 ge- 
nera are peculiar to the island, which also possesses one genus in 
common with the Philippines, one with Sanghir, and one with 
Ceram ; 48 Celebean genera occur in the Indian and not in the 
Australian Region, and 23 in the Australian Region which are 
not found in the Indian ; so that the Celebean Ornis is rather 
more Indian than Australian, while retaining an individuality 
of its owrij The whole paper deserves careful study ; for not 
only is tlie synonymy of each species mentioned very com- 
pletely treated, but a synopsis of many of the genera is added.
