26 VISCOUNT WALDEN ON THE BIRDS OF CELEBES. 



Demiegretta. *Querquedula. Onychoprion. Phalacrocorax. 



Ardeola. Mareca. Pelecanopus. Dysporus. 



Nycticorax. Dendrocygna. Plotus. Podiceps. 



Butorides. Hydrochelidon. 



The following nine genera are peculiar to the island of Celebes: — Meropogon, 

 Monachalcyon, Ceycopsis, Artamides, Gazzola, Streptocitta, Unodes, Scissirostrum, Mega- 

 cephalon. One genus is restricted to Celebes and the Sanghir Islands, Cittttra ; one to 

 Celebes and Philippines, Prioniturus ; and one to Celebes and Ceram, Basilornis. 



Of these twelve genera, Meropogon, Streptocitta, and Basilorms belong to the non- 

 Australian families ; Gazzola to the almost universal Corvinae ; 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 Australian 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 



Picarise 11 3 



Passeres 20 5 



ColumbiB 2 8 



Gallinae 1 1 



GraUse 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. Loriculus 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. amabiJis, a representative form of the Celebean L. stigmatus, 

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



' It is true that Buceros, Alcedo, Budi/tes, and Pratincola occur in some of the Papuan and Moluccan islands ; 

 but they cannot be regarded as genera belonging to the Australian region.
