1871.] VISCOUNT WALDEN ON THE BIRDS OF CELEBES. 333 



One genus is restricted to Celebes and the Sanghir islands, 



Cittura ; 

 one to Celebes and the Philippines, 



Prioniturus ; 

 and one to Celebes and Ceram, 



Basilornis. 



" Of these twelve genera, Meropogon, Strepticitta, and Basilornis 

 belong to the non-Australian families ; Gazzola to the almost uni- 

 versal Corvince ; Monachalcyon, Ceycopsis, and Cittura are isolated 

 genera of a family in which the Australian region is pre-eminently 

 rich ; Enodes and Scissirostrum have affinities with genera common 

 to the Indian and Australian regions ; Megacephalon is strictly 

 Australian. The affinities of Prioniturus seem to be with Australian 

 genera. 



" The total number of Celebean genera also found within the 

 Indian region, but not in the Australian, is forty-eight*. 



" The total number of Celebean genera also occurring in the Aus- 

 tralian region, but not in the Indian, is twenty-three. If we compare 

 these numbers, we find that Celebes contains twenty-five more Indian 

 than Australian genera. 



" If we make the same comparison by orders, the following results 



are obtained : — 



Indian region. Australian region. 



Psittaci 1 3 



Rapaces 10 2 



PicaricB 11 3 



Passeres 20 5 



Columbce 2 8 



Gallince 1 1 



Grallce 2 1 



Anseres 1 



Total 48 23 



" So while the Celebean Rapaces and Passeres contain a large 

 majority of Indian genera, in the Psittaci and Columbce Australian 

 genera preponderate. Loricuhis is classed as an Indian genus ; yet 

 until the zoogeographical positions of the Philippines and of Celebes 

 are determined the zoogeographical characters of Loriculus cannot 

 be established. Within the limits of the Philippine and Celebean 

 areas, seven out of the thirteen known species occur. Another, L. 

 amabilis, a representative form of the Celebean L. stigmatus, occurs 

 in the Sanghir Islands, and is also Papuan, being found at Gilolo and 

 Batchian. The remaining five, one of which (L.Jloscidus) is the Flores 

 representative of the Javan L. pusillus, are peculiar to the Indian 

 region. If, then, we cease to regard Loriculus as having an Indian 



* It is true that Buceros, Alcedo, Biulytcs, and Pratincola occur in some of 

 the Papuan and Molucca n islands ; but they cannot be considered as genera be- 

 longing to the Australian region.
